Title: Hair straightener

Description:
TECHNICAL FIELD 
     This disclosure relates generally to consumer products. More particularly, the disclosure made herein relates to a hair straightener, a hair designer, a hair styler, or hair curler. 
     BACKGROUND 
     Unless otherwise indicated herein, the details in this section are not prior art to the claims in this application and are not admitted to be prior art by inclusion in this section. 
     Hair straighteners are sometimes used to straighten hair, lengthen the perceived length of hair, reduce volume of hair, and/or for other purposes. Hair straighteners have been used for scores of years for these and other purposes. The first known hair straightener was used in 1872 by Marcel Grateau, who used heated rods to style hair. The general idea of hair styling evolved over the next thirty to forty years. 
     In 1909, the first dual iron version of the hair straightener was patented by Isaac K. Shero. The dual iron hair straightener relies upon two heated irons, which are put together with the hair located between the irons. The heat from the heated irons can be used to tease or straighten the hair. Since the invention of the dual iron straightener, however, there have not been extensive changes to the general function and/or structure of the hair straightener.

     DETAILED DESCRIPTION 
     The following detailed description is directed to a hair straightener. In some embodiments a hair straightener can be formed from a plastic or other material. The hair straightener can include a top portion and a bottom portion. The top portion can be joined to the bottom portion by a hinge or other assembly mechanism. In some other embodiments, the top portion and the bottom portion can be formed from one or more pieces of material, and a spring mechanism can be formed between the top portion and the bottom portion. In some embodiments, a user grips the hair straightener by inserting one or more fingers into a top portion of the hair straightener and by inserting a thumb into a bottom portion of the hair straightener. The user can pinch his or her fingers together and/or spread his or her fingers apart to create a gap between two heating plates, one of which can be located on each of the top portion and the bottom portion. 
     In some embodiments, a spring mechanism can be located between the top portion and the bottom portion. The spring mechanism can urge the top portion away from the bottom portion, thereby creating a gap between the heating plates. A user may apply a pressure to the top portion and the bottom portion by way of pinching his or her fingers to urge the heating plates into contact with hair and/or each other. 
     In some other embodiments, the spring mechanism can draw the top portion toward the bottom portion, thereby closing a gap formed between the heating plates. A user may apply a pressure to the top portion and the bottom portion by way of opening a pinch of his or her fingers, thereby creating a gap between the heating plates. Pressure can be released to allow the heating plates to come into contact with each other and/or the hair. These and other aspects of the concepts and technologies described herein for a hair straightener will be illustrated and described in more detail herein. 
     In the following detailed description, references are made to the accompanying drawings that form a part hereof, and in which are shown by way of illustration specific embodiments or examples. It must be understood that the disclosed embodiments are merely illustrative of the concepts and technologies disclosed herein. The concepts and technologies disclosed herein may be embodied in various and alternative forms, and/or in various combinations of the embodiments disclosed herein. The word “illustrative,” as used in the specification, is used expansively to refer to embodiments that serve as an illustration, specimen, model or pattern. 
     Additionally, it should be understood that the drawings are not necessarily to scale, and that some features may be exaggerated or minimized to show details of particular components. In other instances, well-known components, systems, materials or methods have not been described in detail in order to avoid obscuring the present disclosure. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present disclosure. Referring now to the drawings, in which like numerals represent like elements throughout the several figures, aspects of hair straighteners will be presented. 
     Referring first to  FIG. 1 , aspects of a hair straightener  100  according to various embodiments of the concepts and technologies described herein will be described in detail. In particular,  FIG. 1  illustrates one illustrative embodiment of a hair straightener  100 . It should be understood that the illustrated and described illustrative embodiment of the hair straightener  100  shown in  FIG. 1  is one illustrative embodiment of the concepts and technologies described herein, and therefore should not be construed as being limiting in any way of the concepts and technologies described herein. 
     In some embodiments, as shown in  FIG. 1 , a hair straightener  100  can include a hair straightener finger engagement portion (“top portion”)  102  and a hair straightener thumb engagement portion (“bottom portion”)  104 . It should be understood that in some embodiments, the top portion  102  and the bottom portion  104  can be interchanged and/or reversed by users, resulting in the thumb engaging the top portion  102  and/or one or more fingers engaging the bottom portion  104 . As such, it should be understood that the use of the terms “top” and “bottom” are used for convenience of description, and not to limit in any way the scope of the disclosure and/or the appended claims. 
     The top portion  102  can be formed with a hollow end (not visible in  FIG. 1 ) through which one or more fingers of a user can be inserted. According to some embodiments of the hair straightener  100 , the hollow end formed in the top portion  102  can accept one finger of the user. According to some other embodiments of the hair straightener  100 , a hollow end formed in the top portion  102  can accept two fingers of the user. According to yet other embodiments of the hair straightener  100 , the hollow end can accept three fingers of the user. According to still other embodiments of the hair straightener  100 , a hollow end formed in the top portion  102  can accept four fingers of the user. For purposes of illustrating and describing the embodiments of the hair straightener  100  herein, the FIGURES illustrate embodiments in which a hollow end formed in the top portion  102  is configured to accept two or three fingers. In light of the various modifications and/or embodiments mentioned above, it should be understood that the illustrated examples are illustrative and therefore should not be construed as being limiting in any way. 
     According to some embodiments of the hair straightener  100 , the top portion  102  can be formed as a single piece of material and can include one of various configurations. In some other embodiments of the hair straightener  100 , the top portion  102  can be formed by two or more components or portions that can be joined together in various manners. For example, two or more components or portions can be welded together, stitched or sewn together, connected using an adhesive, connected using a thermoforming process such as melting, joined using mechanical fasteners, combinations thereof, or the like. 
     In some embodiments of the hair straightener  100 , the top portion  102  and/or the bottom portion  104  can include a rigid or semi-rigid structure such as acrylic, hard plastics, metal, resins, or the like. In some other embodiments of the hair straightener  100 , the top portion  102  and/or the bottom portion  104  can include a soft structure such as soft plastics, rubber, synthetic rubbers, cloth, combinations thereof, or the like. Various embodiments of the hair straightener  100  will be illustrated and described hereinbelow. 
     The hair straightener  100  can include a cord, in some embodiments, which can connect the hair straightener  100  to an external power source. In some contemplated embodiments, the hair straightener  100  can include an electrical cord, which can be used to electrically connect one or more heating plates (not visible in  FIG. 1 ) of the hair straightener  100  to an external power source (not visible in  FIG. 1 ) such as an outlet, a universal serial bus (“USB”) port, a power adaptor, battery power, or the like. According to some other embodiments, the hair straightener  100  can include an internal power source, which may be disposable, rechargeable, and/or renewable, according to various implementations. Because connecting electrical devices to power sources generally is understood, the various possible configurations of electrical cords or the like are not described further herein for the sake of brevity. 
     The bottom portion  104  also can be formed with a hollow end (not visible in  FIG. 1 ) through which a thumb of a user can be inserted. According to some embodiments of the hair straightener  100 , the hollow end formed in the bottom portion  104  can accept one or more fingers of the user instead of, or in addition to, receiving the thumb of the user. For purposes of illustrating and describing the concepts and technologies described herein, the illustrated embodiments of the bottom portion  104  are shown as including a hollow end that is configured to receive a thumb of a user. In light of the various modifications and/or embodiments mentioned herein, it should be understood that the illustrated examples are illustrative and therefore should not be construed as being limiting in any way. 
     According to various embodiments of the hair straightener  100 , a user of the hair straightener  100  can hold the hair straightener  100  using one or more fingers inserted into the hollow end of the top portion  102  and a thumb inserted into a hollow end of the bottom portion  104 . It should not be construed as being limiting in any way that because of the various configurations of the top portion  102  and/or the bottom portion  104  illustrated and described herein, the hollow end may be omitted in some embodiments. In particular, one or more of the top portion  102  and the bottom portion  104  can include one or more fingertip inserts or sleeves for the fingers and/or thumb. Using the inserts or sleeves, a user may hold the hair straightener  100  without the fingers and/or thumb being enclosed or inserted into hollow ends. 
     Thus, it can be appreciated that straps or other mechanisms also can be used to hold the hair straightener  100  to the fingers and/or thumb. Although these embodiments are contemplated, the appended claims include only embodiments in which the fingers and/or thumb are inserted into hollow ends formed in the top portion  102  and/or the bottom portion  104  unless the claims recite a “top portion without a hollow end” or a “bottom portion without a hollow end.” Thus, the top portion  102  and the bottom portion  104  as used herein and/or recited in the claims, are directed to embodiments in which during use at least a majority of the fingers and/or thumb used to hold the hair straightener  100  are located within the hollow ends during use. 
     As mentioned briefly above, components of the hair straightener  100  can be formed from various materials. According to various embodiments, the top portion  102  of the hair straightener  100 , the bottom portion  104  of the hair straightener  100 , and/or components of the top portion  102  and/or bottom portion  104  can be formed from one or more plastics, one or more thermoplastics, one or more acrylics, one or more resins, one or more polymers or copolymers, other (non-plastic and non-polymer) materials, and/or combinations thereof. According to some embodiments, the top portion  102 , the bottom portion  104 , and/or other components of the hair straightener  100  illustrated and described herein can be formed using various manufacturing processes such as injection molding processes, three dimensional printing processes, machining processes, forging processes, combinations thereof, or the like. Because other materials and/or processes can be used to form the top portion  102 , the bottom portion  104 , and/or other components of the hair straightener  100 , it should be understood that these examples are illustrative and therefore should not be construed as being limiting in any way. 
     The hair straightener  100  shown in  FIG. 1  has been described as including one top portion  102  and one bottom portion  104 . It should be understood, however, that some embodiments of the hair straightener  100  can include zero, one, or more than one top portion  102  and zero, one, or more than bottom portion  104 . Thus, some embodiments of the hair straightener  100  can include two top portions  102 , two bottom portions  104 , and/or other structures instead of, or in addition to, the top portion  102  and/or the bottom portion  104 . It therefore should be understood that the example embodiment shown in  FIG. 1  is illustrative of the concepts and technologies described herein and therefore should not be construed as being limiting in any way. 
     Turning to  FIG. 2 , one example operating environment of the hair straightener  100  is shown. As can be seen in  FIG. 2 , various embodiments of the hair straightener  100  can be held by a single hand  200  of a user. Thus, the hair straightener  100  may be operated (e.g., opened and/or closed) by a user by opening and/or pinching fingers of his or her hand  200 . According to various embodiments, the configuration of the hair straightener  100 , the ability of a user to wield the hair straightener  100  in one hand  200 , and the ability of a user to open and close the hair straightener  100  by way of a natural pinching movement or of the like, can result in ease of use of the hair straightener  100 , prevention of hand and/or arm fatigue of the user, and an ability to use the hair straightener  100  in a natural manner. It should be understood that this example is illustrative and therefore should not be construed as being limiting in any way. 
     In some embodiments of the hair straightener  100 , a scalp side  202  of the hair straightener  100  can be formed with a configuration that may differ from a configuration of a knuckle side  204  of the hair straightener  100 . Thus, some embodiments of the hair straightener  100  can include various mechanisms for joining the top portion  102  to the bottom portion  104 , wherein the various mechanisms may be located on the knuckle side  204  of the hair straightener  100  so that the scalp side  202  can be brought into close proximity with the scalp and/or hair. In other words, if the mechanisms that join the top portion  102  to the bottom portion  104  are bulky, these mechanisms can be located at the knuckle side  204 , in some embodiments, to allow easier access to the scalp and/or hair of a user. It should be understood that this example is illustrative and therefore should not be construed as being limiting in any way. 
     Turning now to  FIGS. 3A-3B , additional aspects of the concepts and technologies described herein for a hair straightener will be described in detail. In particular,  FIG. 3A  is a perspective view of a hair straightener  100 , according to another illustrative embodiment. As shown in  FIG. 3A , the hair straightener  100  can include various decorative structures, surfaces, coatings, or the like. In  FIG. 3A , the top portion  102  of the hair straightener  100  can include a top portion decorative molding (“top decorative molding”)  300 , and the bottom portion  104  of the hair straightener  100  can include a bottom portion decorative molding (“bottom decorative molding”)  302 . One or more of the top decorative molding  300  and the bottom decorative molding  302  can be included merely for decoration, in some embodiments. 
     In some other embodiments, one or more of the top decorative molding  300  and the bottom decorative molding  302  can be included to provide functionality to the hair straightener  100 . For example, in some embodiments one or more of the top decorative molding  300  and the bottom decorative molding  302  can be included to reinforce ends of the top portion  102  and/or the bottom portion  104 . For example, one or more of the top portion  102  and the bottom portion  104  may be formed from a soft fabric, silicone, or other material that may be reinforced by a hard plastic, metal, or other material used to form one or more of the top decorative molding  300  and the bottom decorative molding  302 . In some other embodiments, the one or more of the top decorative molding  300  and the bottom decorative molding  302  can be included to provide a polished and/or smooth surface to reduce or eliminate snagging of a user&#39;s hair while using the hair straightener  100 . 
     In still other embodiments, one or more of the top decorative molding  300  and the bottom decorative molding  302  can be included to protect a seam or stitching that may be included on the top portion  102  and/or the bottom portion  104  to enhance the durability of the hair straightener  100 . Because one or more of the top decorative molding  300  and the bottom decorative molding  302  can be included for additional or alternative reasons, and because one or more of the top decorative molding  300  and the bottom decorative molding  302  can be omitted in some embodiments, it should be understood that these examples are illustrative and therefore should not be construed as being limiting in any way. 
     As shown in  FIG. 3A , the hair straightener  100  also can include a hinge  304 . The hinge  304  can be included in the hair straightener  100  to provide an axis of rotation about which the top portion  102  and/or the bottom portion  104  rotate. It can be appreciated with reference to  FIG. 3A , that a hand  200  or a portion thereof of a user may engage an outside surface of the hinge  304 , in some embodiments. In some other embodiments, the hinge  304  can be covered by other surfaces, structures, paddings, or the like, and/or the hinge  304  may be configured such that a hand  200  or a portion thereof of a user may not engage the hinge  304 . Additional details of the hinge  304  are illustrated and described below. 
     Referring now to  FIG. 3B , additional aspects of the concepts and technologies described herein for a hair straightener  100  are illustrated and described in detail. In particular,  FIG. 3B  is a side elevation view of the hair straightener  100  shown in  FIG. 3A , according to one example embodiment of the concepts and technologies described herein. As can be seen in  FIG. 3B , a top lining  306  can extend over the hinge  304  and/or a portion thereof. Thus, as mentioned above with reference to  FIG. 3A , a hand  200  of a user may engage the top lining  306  instead of, or in addition to, engaging an outer surface of the hinge  304 . It should be understood that this example is illustrative and therefore should not be construed as being limiting in any way. 
     The top lining  306  can include various materials and/or combinations of materials. In some embodiments of the concepts and technologies described herein, the top lining  306  can be provided by a foam or other insert as a substrate (not visible in  FIG. 3B ), which can be covered by a fabric, rubber, cloth, or other material. Thus, the top lining  306  can be a padded insert that can provide a soft surface to engage fingers or a thumb of a hand  200  of a user. It should be understood that this example is illustrative and therefore should not be construed as being limiting in any way. 
     Similarly, a bottom lining  308  can extend over the hinge  304  and/or a portion thereof. Thus, the hand  200  of a user may engage the bottom lining  308  instead of, or in addition to, engaging an outer surface of the hinge  304 . According to various embodiments, the bottom lining  308  can be formed in a manner similar or even identical to a manner used to form the top lining  306 . Furthermore, the bottom lining also can include various materials and/or combinations thereof. Thus, the bottom lining  308  can be a padded insert that can provide a soft surface to engage fingers or a thumb of a hand  200  of a user. 
     It therefore can be appreciated that in some embodiments, the hand  200  of a user may engage the top lining  306  and the bottom lining  308  instead of the hinge  304 . In some other embodiments, the hand  200  of the user may engage the top lining  306 , the bottom lining  308 , and the hinge  304  and/or a portion thereof. It should be understood that these examples are illustrative and therefore should not be construed as being limiting in any way. 
     As is visible in  FIG. 3B , the hair straightener  100  also can include a top portion heating plate (“top heating plate”)  310  and a bottom portion heating plate (“bottom heating plate”)  312 . In some embodiments, one or more of the top heating plate  310  and the bottom heating plate  312  can be formed as an assembly of two or more components, as will be illustrated and described herein with reference to  FIGS. 5-6 . In some other embodiments, one or more of the top heating plate  310  and the bottom heating plate  312  can be provided by a unitary structure (e.g., a heated plate). Because one or more of the top heating plate  310  and the bottom heating plate  312  can be provided by various structures including, but not limited to, those illustrated and described herein, it should be understood that the illustrated embodiments are illustrative and should not be construed as being limiting in any way. 
     The top heating plate  310  and the bottom heating plate  312  can be attached to the top portion  102  and the bottom portion  104 , respectively. The top heating plate  310  and the bottom heating plate  312  can be configured such that the hair of user can be located or disposed between the top heating plate  310  and the bottom heating plate  312  to straighten the hair of a user. Thus, it can be appreciated that in the embodiment shown in  FIGS. 3A-3B , the top heating plate  310  and the bottom heating plate  312  can be rotated about an axis of the hinge  304 , and therefore can be rotated into and out of a hair-engagement configuration by pinching or opening a grip of a user. 
     As is shown in  FIG. 3B , the top portion  102  also can include a top portion hollow end (“top hollow end”)  314  into which one or more fingers of a hand  200  of a user can be inserted. Similarly, the bottom portion  104  can include a bottom portion hollow end (“bottom hollow end”)  316  into which a thumb or finger of a hand  200  of a user can be inserted. Additional features of some embodiments of the top hollow end  314  and the bottom hollow end  316  are illustrated and described herein, particularly with reference to  FIGS. 15-24 . 
     In practice, a user may grip the hair straightener  100  in his or her hand  200 . The user may open his or grip, thereby moving the top portion  102  away from the bottom portion  104 . As a result of this movement, the top heating plate  310  and the bottom heating plate  312  also can be moved away from one another, thereby creating a gap between the top heating plate  310  and the bottom heating plate  312 . 
     The user can locate his or her hair into the gap formed by opening his or her hand  200 . When a desired portion of the hair is located within the gap, the user can pinch or otherwise close his or her hand, thereby moving the top portion  102  toward the bottom portion  104  until the top heating plate  310  and the bottom heating plate  312  contact the hair and/or each other. The hair straightener  100  can be held in this orientation for a particular period of time during which the hair can be straightened, flattened, or the like. In some embodiments, one or more of the top heating plate  310  and the bottom heating plate  312  can be configured with surface structures such as ridges, or the like, to allow a user to apply waves or the like to his or her hair. Similarly, one or more of the top heating plate  310  and the bottom heating plate  312  can have a curved surface to allow a user to apply curls to his or her hair. Thus, the various embodiments of the hair straightener  100  illustrated and described herein should be understood as being applicable to other hair devices such as hair curlers, hair designers, hair stylers, combinations thereof, or the like. 
     Thus, embodiments of the concepts and technologies described herein can be used to provide an easy to use and ergonomic hair straightener  100  that may be used by a user using natural hand movements (pinching the fingers, opening the fingers, or the like). It should be understood that this example is illustrative and therefore should not be construed as being limiting in any way. 
     Turning now to  FIG. 4 , additional aspects of the concepts and technologies described herein for a hair straightener  100  will be described in detail. In particular,  FIG. 4  is a top or bottom elevation view of the hair straightener  100  in an opened configuration. It should be understood that the top portion  102  and the bottom portion  104  illustrated in  FIG. 4  may not be connected to one another in the illustrated configuration. In particular, a hinge  304 , the top lining  306  and/or the bottom lining  308 , or other components of the hair straightener  100  may limit rotation of the top portion  102  and/or the bottom portion  104  such that the illustrated configuration may not be possible once the hair straightener  100  is assembled. As such, it should be understood that the illustrated configuration is provided for the purpose of illustrating and describing the concepts and technologies described herein and therefore should not be construed as being limiting in any way. 
     As shown in  FIG. 4  the top portion  102  can include a top portion heating plate insulator  400 . The top portion heating plate insulator  400  can be located between the top heating plate  310  and a bottom surface of the top portion  102 . Thus, it can be appreciated that the top portion heating plate insulator  400  can be provided to insulate heat from the top heating plate  310  and/or the bottom heating plate  312  from the top portion  102 , structures and/or components thereof, and/or fingers of a hand  200  of a user inserted into the top portion  102 . 
     As shown in  FIG. 4  the bottom portion  104  can include a bottom portion heating plate insulator  402 . The bottom portion heating plate insulator  402  can be located between the bottom heating plate  312  and a top surface of the bottom portion  104 . Thus, it can be appreciated that the bottom portion heating plate insulator  402  can be provided to insulate heat from the bottom heating plate  312  and/or the top heating plate  310  from the bottom portion  104 , structures and/or components thereof, and/or a thumb of a hand  200  of a user inserted into the bottom portion  104 . 
     One or more of the top portion heating plate insulator  400  and the bottom portion heating plate insulator  402  can be formed from various insulating materials such as, for example, foils, silicon, thinsulate or other synthetic fiber insulation, rubber, various polymers, TEFLON brand materials, glass-filled and/or ceramic-filled NYLONs or other materials, epoxies, or the like. According to various embodiments, one or more of the top portion heating plate insulator  400  and the bottom portion heating plate insulator  402  can be formed as rigid, semi-rigid, semi-flexible, and/or flexible surfaces. As such, it should be understood that various insulating materials can be used for one or more of top portion heating plate insulator  400  and the bottom portion heating plate insulator  402  without departing from the scope of the concepts and technologies described herein. 
     Turning now to  FIG. 5 , additional aspects of the concepts and technologies described herein for a hair straightener  100  will be described in detail. In particular,  FIG. 5  is a side elevation view of part of the top portion  102 , according to one example embodiment of the concepts and technologies described herein. It should be understood that illustrated embodiment is illustrative of one contemplated embodiment and therefore should not be construed as being limiting in any way. 
     As shown in  FIG. 5 , the top heating plate  310  can include one or more components. In the illustrated embodiment, the top heating plate  310  can include a heating element housing  500 . The heating element housing  500  can be configured to receive, secure, and/or otherwise house a heating element  502 . The heating element housing  500  can be made from ceramics; metals or alloys such as aluminum, steel, brass, or the like; or other materials. As can be seen in  FIG. 5 , the heating element housing  500  can include a sleeve, holster, or hollow (“sleeve”)  504  in which the heating element  502  can be disposed or located. 
     In some embodiments of the heating element housing  500 , the heating element  502  can be permanently mounted in the sleeve  504 . For example, the heating element  502  can be attached to the heating element housing  500  using one or more of adhesive, a mechanical fastener, a chemical bonding process, or the like. Additionally, or alternatively, the heating element  502  may be thermally bonded or welded to the heating element housing  500 , in some embodiments. It should be understood that these examples are illustrative and therefore should not be construed as being limiting in any way. 
     In some other embodiments, the heating element  502  can be semi-permanently located or disposed within the sleeve  504 . For example, the heating element  502  can be attached to the heating element housing  500  using a releasable bond or adhesive. In some other embodiments, the heating element  502  can be joined or attached to the heating element housing  500  using a bond, adhesive, or fastener that may require a process, solvent, or machining to remove and as such, may be considered semi-permanently bonded. It should be understood that these examples are illustrative and therefore should not be construed as being limiting in any way. 
     In yet other embodiments, the heating element  502  may be removable located or disposed within the heating element housing  500 . For example, the heating element  502  may be attached to the heating element housing  500  using a removable mechanical fastener such as a screw, pin, clamp, or the like. In yet other embodiments, an access to the sleeve  504  can be exposed when the heating element  502  is inserted into the sleeve  504  and blocked after assembly. Thus, for example, a pocket, passageway, or the like can be provided within one or more portions of the hair straightener  100 , and the heating element  502  can be passed through the pocket, passageway, or the like into the sleeve  504 , after which the pocket, passageway, or the like can be sealed. It should be understood that these examples are illustrative and therefore should not be construed as being limiting in any way. 
     Although  FIG. 5  is illustrated and described with respect to the top portion  102  and the various components thereof (e.g., the top heating plate  310 , the top portion heating plate insulator  400 , etc.), it should be understood that the bottom portion  104  and/or the bottom heating plate  312  can be similarly configured, though this is not necessarily the case. Thus, it should be understood that the bottom heating plate  312  of the bottom portion  104  can be configured in a manner that is similar or even identical to the configuration of the top heating plate  310  of the top portion  102 . It should be understood that this example is illustrative and therefore should not be construed as being limiting in any way. 
     Turning now to  FIG. 6 , additional aspects of the concepts and technologies described herein for a hair straightener  100  will be described in detail. In particular,  FIG. 6  illustrates a heating element  502 , according to some example embodiments of the concepts and technologies described herein. It should be understood that the example heating element  502  shown in  FIG. 6  is illustrative and therefore should not be construed as being limiting in any way. 
     As shown in  FIG. 6 , the heating plate can be formed in some embodiments from a substrate  600 . The substrate  600  can be formed from one or more metals or alloys; glasses, ceramics, porcelains, or the like; plastics, thermoplastics, other polymers, or the like; and/or combinations thereof. In some embodiments, the substrate  600  can be formed from a material that may conduct heat efficiently such as copper, aluminum, steel, ceramic, other metals, other alloys, other glasses, plastics, combinations thereof, or the like. The material used to form the substrate  600  can be rigid, semi-rigid, semi-flexible, or flexible. 
     The heating element  502  also can include a conductive coil  602 . It can be appreciated that the conductive coil  602  can be attached to the substrate  600 , formed in the substrate  600 , and/or otherwise located at the substrate  600 . In some embodiments, for example, the substrate  600  can be formed from a metal or alloy, and the conductive coil  602  can be attached to the substrate  600  using an adhesive and/or other mechanical, chemical, or other bonding processes. In some other embodiments, the substrate  600  can be formed from a ceramic, and the conductive coil  602  can be formed inside of the substrate  600 . In yet other embodiments, a recess can be formed in the substrate  600  and the conductive coil  602  can be disposed within the recess. Because there are various approaches that may be used to locate the conductive coil  602  at the substrate  600 , it should be understood that these examples are illustrative and therefore should not be construed as being limiting in any way. 
     As shown in  FIG. 6 , the heating element  502  also can include a positive electrical connector  604  and a negative electrical connector  606 . Thus, a current can be applied across the conductive coil  602  and the conductive coil  602  can be heated by resistance. As such, it can be appreciated that the conductive coil  602  can be formed by a conductive, yet resistive material such as steel, tungsten, aluminum, copper, other materials, or the like. Furthermore, it should be understood that the conductive coil  602  can be printed on the substrate  600 , in some embodiments, so it should be understood that the conductive coil  602  can be formed from a conductive ink. It should be understood that these examples are illustrative and therefore should not be construed as being limiting in any way. 
     According to various embodiments, a current can be applied to the conductive coil  602  via the positive electrical connector  604  and a negative electrical connector  606  by a power source  608 . Various embodiments of the concepts and technologies described herein can include various types of power sources  608 . For example, the power source  608  can include an electrical outlet, and as such the power may be supplied by a utility company, an on-site generator, a vehicle, or the like. As such, it should be understood that the hair straightener  100  can be joined to the power source  608  by an electrical cord (not shown in the FIGURES). It should be understood that this example is illustrative and therefore should not be construed as being limiting in any way. 
     In some other embodiments, the power source  608  can be internal to the hair straightener  100 . As such, it should be understood that the power source  608  can include one or more battery. The one or more battery can include a disposable battery, a rechargeable battery, a renewable battery, combinations thereof, or the like. It should be understood that in some embodiments a battery may be inefficient for purposes of heating a conductive coil  602  as illustrated and described herein. As such, some embodiments of the hair straightener  100  can include an internal power source  608 , an external power source  608 , and/or an electrical bypass switch. The electrical bypass switch can be used to bypass the internal power source  608  when the external power source  608  is in use and/or to bypass power to a charging mechanism to charge the internal power source  608  when the hair straightener  100  is not in use and/or when the hair straightener  100  is in use. It should be understood that these examples are illustrative and therefore should not be construed as being limiting in any way. 
     Regardless of how the power source  608  is configured, and regardless of whether the power source  608  is configured as an alternating current or direct current device, the power source  608  can include a positive power source lead  610  and a negative power source lead  612 . The positive power source lead  610  can be connected to the positive electrical connector  604  of the heating element  502 , and the negative power source lead  612  can be connected to the negative electrical connector  606  of the heating element  502 . The connection between the positive power source lead  610  and the positive electrical connector  604  can be provided by an electrical cable, wiring, conductive traces or the like. Similarly, the connection between the negative power source lead  612  and the negative electrical connector  606  can be provided by an electrical cable, wiring, conductive traces or the like. It should be understood that these examples are illustrative and therefore should not be construed as being limiting in any way. 
     Turning now to  FIG. 7 , additional aspects of the hair straightener  100  according to various embodiments of the concepts and technologies described herein will be described in detail. In particular,  FIG. 7  illustrates an assembly drawing of a hair straightener  100  according to another embodiment. It should be understood that the illustrated and described illustrative embodiment of the hair straightener  100  is one illustrative embodiment of the concepts and technologies described herein, and therefore should not be construed as being limiting in any way of the concepts and technologies described herein. 
     In some embodiments, as mentioned above and as shown in  FIG. 7 , the hair straightener  100  can include an assembly formed by joining together the top portion  102  and the bottom portion  104 . The top portion  102  can be configured to be engaged, attached to, connected to, mated to, joined to, and/or otherwise assembled with the bottom portion  104 . In some other embodiments, the top portion  102  and the bottom portion  104  can be formed as a solid and/or unitary structure, though this embodiment is not shown in  FIG. 7 . 
     As shown in  FIG. 7 , the top portion  102  and the bottom portion  104  can be assembled together using an assembly mechanism  700 . The assembly mechanism  700  can include, for example, a pin, a bolt, a rivet, a screw, a latch, and/or other mechanisms. In one contemplated embodiment, the assembly mechanism  700  includes a pin that can be inserted through one or more assembly mechanism passageways  702 A- 702 C. It therefore can be appreciated that the assembly mechanism  700  and the assembly mechanism passageways  702 A- 702 C can collective provide the functionality associated with the hinge  304  illustrated and described above. It should be understood that this example is illustrative and therefore should not be construed as being limiting in any way. 
     According to various embodiments of the concepts and technologies described herein, the assembly mechanism  700  can be removable and/or can be removed from the hair straightener  100 . The one or more assembly mechanism passageways  702 A- 702 C can cooperatively form a single assembly passageway, though this is not necessarily the case. In particular some embodiments of the concepts and technologies described herein include omitting portions of one or more of the assembly mechanism passageways  702 A- 702 C, omitting one or more of the assembly mechanism passageways  702 A- 702 C, combining one or more of the assembly mechanism passageways  702 A- 702 C, or the like. As such, the illustrated embodiment should be understood as one example embodiment and should not be construed as being limiting in any way. 
     In some embodiments, the assembly mechanism  700  can be inserted through the one or more assembly mechanism passageways  702 A- 702 C (and/or the assembly passageway), and a securing mechanism such as a lynchpin, nut, or the like can be attached to the assembly mechanism  700  to hold the assembly mechanism in position. Additionally, or alternatively, if a permanent or semi-permanent fastener is used as the assembly mechanism  700 , the assembly mechanism  700  can be inserted into the assembly mechanism passageways  702 A- 702 C (and/or the assembly passageway), and the assembly mechanism  700  can be deformed, welded, and/or otherwise permanently or semi-permanently locked into position. According to various embodiments, the assembly mechanism  700  and one or more of the assembly mechanism passageways  702 A- 702 C can be formed from a polymer, and as such one or more the assembly mechanism and the assembly mechanism passageways  702 A- 702 C can be thermoformed to permanently and/or semi-permanently join the top portion  102  to the bottom portion  104 . It should be understood that this example is illustrative and therefore should not be construed as being limiting in any way. Because various types of fasteners that can be used as the assembly mechanism  700  are generally understood, the assembly mechanism  700  will not be described in further detail. 
     Although not visible in  FIG. 7 , it should be understood that a spring or spring mechanism can be located between the top portion  102  and the bottom portion  104  in some embodiments. In some other embodiments, the top portion  102  and the bottom portion  104  can be formed as a single part and can be formed such that a spring force is applied to the top portion  102  and the bottom portion  104  without adding separate springs. This will be more clearly understood with reference to  FIG. 8A  below. 
     As mentioned above, the hair straightener  100  and/or the components of the hair straightener  100  (e.g., the top portion  102 , the bottom portion  104 , and/or the assembly mechanism  700 ) can be formed from various materials. According to various embodiments of the concepts and technologies described herein, the hair straightener  100 , or portions or components thereof, can be formed from metals and/or metal alloys such as steel, aluminum, titanium, brass, copper, magnesium alloys, aluminum alloys, other metals or alloys, combinations thereof, or the like. 
     In some embodiments, one or more components of the hair straightener  100  can be formed from non-metal and/or non-metal-alloy materials such as resins, polymers, and/or other materials. In some embodiments, for example, the hair straightener  100 , or a portion thereof, can be formed from resins such as epoxy resins, or the like. In some embodiments, for example, the hair straightener  100 , or a portion thereof, can be formed from one or more polymers such as various thermoplastics, polypropylene, polycarbonates, aerogel, graphite filled NYLON, phenolics, polyimides, and/or other polymers, combinations thereof, or the like. Because the hair straightener  100  can be formed from additional and/or alternative materials, it should be understood that these examples are illustrative and therefore should not be construed as being limiting in any way. 
     In some embodiments, one or more surfaces of the hair straightener  100  and/or the components of the hair straightener  100  (e.g., the top portion  102 , the bottom portion  104 , and/or the assembly mechanism  700 ) can be painted, dyed, coated, or otherwise treated for decorative and/or functional purposes. According to various embodiments of the concepts and technologies described herein, the hair straightener  100  and/or the components of the hair straightener  100  (e.g., the top portion  102 , the bottom portion  104 , and/or the assembly mechanism  700 ) can be polished, sandblasted, painted, coated, or otherwise treated to provide a color, and/or to provide a tactile finish to the surface. Thus, for example, the surface can be smooth, semi-smooth, and/or unsmooth to provide various surface appearances and/or to make the surfaces easier to grip by a user. Because additional and/or alternative treatment processes are possible and are contemplated, it should be understood that these examples are illustrative and therefore should not be construed as being limiting in any way. 
     Referring now to  FIGS. 8A-8B , additional aspects of the concepts and technologies described herein for a hair straightener  100  will be described in detail. In particular,  FIG. 8A  illustrates a side elevation view of a spring mechanism  800  that can be used in various embodiments of the concepts and technologies described herein. As can be seen in  FIG. 8A , the spring mechanism  800  can be located within the hair straightener  100 . According to some embodiments, the spring mechanism  800  can provide the functionality of the hinge  304  as well as a spring. 
     In particular, the spring mechanism  800  can be formed from a single piece of material such as steel, nickel, or the like, and can provide a springing force that can push the top portion  102  away from the bottom portion  104 , or pull the top portion  102  toward the bottom portion  104 . Thus, some embodiments of the hair straightener  100  illustrated and described herein can include the spring mechanism  800  shown in  FIG. 8A  and can be operated by a user by either applying a force to separate the top portion  102  from the bottom portion  104  (and thereby create a gap between the top heating plate  310  and the bottom heating plate  312 ), or by applying a force to move the top portion  102  toward the bottom portion  104  (and thereby closing a gap between the top heating plate  310  and the bottom heating plate  312 ). It should be understood that these examples are illustrative and therefore should not be construed as being limiting in any way. 
     Only the top portion  102  is shown in  FIG. 8A  so as not to obscure the view of the spring mechanism  800 . It should be understood that the bottom portion  104  can be located in an arrangement that may be similar to the arrangement in which the top portion  102  is located, albeit in a mirror-image arrangement. It should be understood that this example is illustrative and therefore should not be construed as being limiting in any way. 
     Turning now to  FIG. 8B , another embodiment of a spring mechanism  800  that can be used in accordance with various embodiments of the concepts and technologies described herein for a hair straightener  100  is shown. As can be seen in  FIG. 8B , the spring mechanism  800  can be provided by a spring. The spring mechanism  800  shown in  FIG. 8B  can be located within a hinge such as the hinge  304 , in some embodiments. In some other embodiments, the spring mechanism  800  shown in  FIG. 8B  can be disposed between the top portion  102  and the bottom portion  104 . 
     Regardless of where the spring mechanism  800  is located, the spring mechanism  800  shown in  FIG. 8B  may, as described above with regard to the spring mechanism  800  shown in  FIG. 8A , provide a springing force that can push the top portion  102  away from the bottom portion  104  or pull the top portion  102  toward the bottom portion  104 . Thus, some embodiments of the hair straightener  100  illustrated and described herein can include the spring mechanism  800  shown in  FIG. 8B  and can be operated by a user by either applying a force to separate the top portion  102  from the bottom portion  104  (and thereby create a gap between the top heating plate  310  and the bottom heating plate  312 ), or by applying a force to move the top portion  102  toward the bottom portion  104  (and thereby closing a gap between the top heating plate  310  and the bottom heating plate  312 ). It should be understood that these examples are illustrative and therefore should not be construed as being limiting in any way. 
     Turning now to  FIGS. 9-24 , additional aspects of the concepts and technologies described herein for a hair straightener  100  will be described in detail. Turning first to  FIG. 9 , a perspective view of a hair straightener  100  is shown, according to some illustrative embodiments. As shown in  FIG. 9 , the top portion  102  and/or the bottom portion  104  of the hair straightener  100  can be formed from soft silicone or other materials. In the illustrated embodiment, soft silicone is used, and the top portion  102  and the bottom portion  104  are formed from a single piece of silicone. Other components of the hair straightener  100  can be formed from various materials including rigid, semi-rigid, semi-flexible, and/or flexible materials. In some embodiments, the soft silicone may be a preferred material because the soft silicone may be waterproof. 
     Also shown in  FIG. 9  is one embodiment of the power source illustrated and described herein. In particular,  FIG. 9  illustrates an illustrative power cord  900 . As generally is understood, the power cord  900  can be of various lengths and/or configurations, and can include a plug  902  or other structures for coupling the hair straightener  100  to a source of power such as a battery source, a power outlet, or the like. While the illustrated plug  902  includes only two prongs, it should be understood that any number of prongs may be included to accommodate grounded and/or multi-phase power sources. As such, it should be understood that the illustrated example is illustrative and therefore should not be construed as being limiting in any way. 
     Turning now to  FIG. 10 , a perspective view of a hair straightener  100  is shown, according to some illustrative embodiments. As shown in  FIG. 10 , the top portion  102  and/or the bottom portion  104  of the hair straightener  100  can be formed from a fabric, leather, synthetic leather, and/or other materials that may be stitched together. In the illustrated embodiment, the materials can be stitched together using one or more decorative stitches  1000 . Other components of the hair straightener  100  can be formed from various materials including rigid, semi-rigid, semi-flexible, and/or flexible materials. It should be understood that this example is illustrative and therefore should not be construed as being limiting in any way. 
     Turning now to  FIG. 11 , a perspective view of a hair straightener  100  is shown, according to some illustrative embodiments. As shown in  FIG. 11 , the top portion  102  and/or the bottom portion  104  of the hair straightener  100  can be formed from soft silicone, fabric, hard plastic, leather, or other materials. In the illustrated embodiment, soft silicone is used, though this is not necessarily the case. In the embodiment shown in  FIG. 11 , a hard plastic, metal, or other material can be included to provide a spring and/or hinge assembly (“spring/hinge assembly”)  1100 . Thus, the top portion  102  and the bottom portion  104  can be held together and/or sprung apart or together by the spring/hinge assembly  1100 . 
     The embodiment shown in  FIG. 11  also includes an inner  1102  that can be formed from a rigid material such as metal, wood, bamboo, hard plastic, other materials, combinations thereof, or the like. Other components of the hair straightener  100  can be formed from various materials including rigid, semi-rigid, semi-flexible, and/or flexible materials.
