## Title
Seamless hair extension system and method of use

## Abstract

The present invention consists of a seamless self-adhesive hair extension and a method of attaching it to a head of a wearer. The seamless self-adhesive hair extension is comprised of a plurality of either natural or synthetic hair strands attached to a base support made of polyurethane which has a rectangular strip of double-sided self-adhesive tape with a removable backing as a fastener. The method consists of separating a user's hair along a part line into an upper portion and a lower portion, wherein the upper portion and lower portion are temporarily swept up and away from the part line. Another double-sided rectangular strip of self-adhesive tape is placed along a lower portion part line approximately 1⁄4′′ from the scalp onto the user's natural hair, and then alternating 1⁄4′′ strands of the user's natural hair are withdrawn from the upper portion of hair above the part line such that the strands will be laid upon the double-sided self-adhesive tape. The removable backing is removed from the tape that is attached to the hair extension or ventilated polyurethane strip, thereby exposing the self-adhesive tape; and the self-adhesive hair extension or ventilated polyurethane strip is applied to the other double face tape on the user's head which contains the strands of the user's natural hair.

## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention is concerned with the field of devices and methods that provide an appearance of longer or thicker hair. More specifically, the invention is concerned with a hair attachment comprised of natural or synthetic hair that is releasably attached directly to hair of a wearer in order to provide the wearer with an appearance of highlighted and or longer and or thicker hair, without causing any tension to the wearer's scalp and or hair.
It is a common desire among many people to acquire hair that is longer and thicker than that which they posses for a variety of reasons, such as self esteem and satisfaction, quickly changing fashion styles, and the like. For example, short hair, which is in fashion for a period of time, may quickly be replaced as current fashion with longer fuller hairstyles. In another example, bangs worn on a forehead may be in fashion for the winter and by the summer this style may be quickly replaced by another style. As hair grows at a rate of approximately less than one inch per month, many people find that it is exceedingly difficult to acquire a contemporary hairstyle in a reasonable time. Even when someone possesses hair of substantial length, the hair may lack thickness or overall volume to achieve a desirable hairstyle. People may also want to add highlights to their hair without having to cause damage to their hair.
Various devices and techniques are available in the prior art and in the marketplace that attempt to satisfy a need and desire for longer and thicker hair. A common well known device is a wig. Although wigs provide a quick and simple means to achieve longer hair, they do not present a fully natural appearance, a condition that leads to their recognition when they are being worn. More recently, a variety of more natural hair enhancement techniques have become popular with a variety of users. These consist of hair weaves, hair extensions, hair braiding and the like, whereby natural or synthetic hair is attached to a scalp of existing hair of a wearer by a variety of techniques in order to provide an appearance of longer, thicker hair without a noticeable artifice of a wig. These techniques and systems, which overcome obvious disadvantage of a wig, also suffer from several drawbacks as they are relatively expensive and time consuming to acquire and frequently discomfort the wearer during application, as well as possibly being difficult to maintain.
2. Description of the Prior Art
Numerous designs, devices, and methods for lengthening and enhancement have been provided in the prior art. Even though these designs may be suitable for specific individual purposes to which they are addressed, they would not be suitable for purposes of the invention as they involve relatively elaborate and time consuming techniques and methods as referenced earlier. These techniques are exemplified by: U.S. Pat. No. 5,072,745, Hair Extension Process, issued to Cheh on Dec. 17, 1991; U.S. Pat. No. 5,107,867, Process for Extending Human Hair, issued to Barrington on Apr. 28, 1999; U.S. Pat. No. 5,868,145, Hair Extension and Thickening process, issued to Spann on Feb. 9, 1999; U.S. Pat. No. 5,881,737, Method of Attaching A Hair Weft To The Hair Of A Wearer, issued to Nelson on Mar. 16, 1999; and U.S. Pat. No. 6,405,736, Method of Using A Self Adhesive Hair Extension, issued to Townsend on Jun. 18, 2002, which discloses a hair attachment device designed to provide an appearance of longer, thicker, and fuller hair. The attachment device consists of a quantity of natural or synthetic human hair that is sewn to a rectangular shaped, self-adhesive tape having a removable back, which is applied to a scalp or hair of a wearer in a releasably engageable manner. While a hair attachment is relatively simple to apply, the self-adhesive tape provides a less than adequate means to secure ends of strands of natural or synthetic hair, which can become prematurely separated from the self-adhesive tape and become unusable in the future.
As such, it may be appreciated that there is a continuing need for a new and improved method and device for providing an appearance of longer and thicker hair in a manner that is relatively simple and inexpensive to achieve. In these respects, the present invention substantially departs from conventional concepts and designs of the prior art, and in so doing provides an apparatus that substantially fulfills this need. Additionally, the aforementioned patents and commercial techniques do not suggest the present inventive combination of component elements arranged and configured as disclosed herein.
The present invention achieves its intended purposes, objects, and advantages through a new, useful and unobvious combination of method steps and component elements, with use of a minimum number of functioning parts, at a reasonable cost to manufacture, and with use of readily available materials.
SUMMARY OF THE INVENTION
The present invention, which will be described in greater detail hereinafter, relates to a field of devices and methods that provide an appearance of longer, thicker or highlighted hair. More specifically, the invention is concerned with a hair attachment comprised of natural or synthetic hair that is releasably attached directly to hair of a wearer to provide the wearer with an appearance of longer, thicker or highlighted hair. The invention overcomes all of the shortcomings listed previously, in addition to providing novel aspects that will be described in detail hereinafter.
Described briefly, according to a typical embodiment, the invention presents a hair attachment device or hair extension that is releasably attached to hair of a wearer in order to provide an appearance of longer, thicker fuller and/or highlighted hair without use of chemicals that will cause damage to the wearer's hair and/or scalp. The hair extension thus allows the wearer to change an appearance of their hair without chemical damage in order to achieve fashion styles that use longer hair, or simply to enhance his/her appearance by achieving particular hair designs heretofore impossible without aid of a hair extension and/or damaging chemicals. The hair extension that is the subject of the instant invention consists of a quantity of natural or synthetic hair strands that are disposed in a parallel relationship and are attached or secured at one end to a flexible strip of polyurethane. The polyurethane securely anchors the hair strands to one end of a double face adhesive tape so that the strands do not become separated from the double face adhesive tape. This ventilated strip of polyurethane is sufficiently flexible to accommodate a shape of the wearer's head. A fastener comprised of a rectangular strip of self-adhesive double-sided tape with a removable backing is attached to the ventilated polyurethane strip in order to provide adhesion necessary to secure the hair extension to hair of the wearer. The hair extension can be applied to the wearer's hair in various quantities and locations thereon as needed to achieve a desired look and appearance. The hair extension may be reused as well by simply wetting the fastener, or double-sided self-adhesive tape on the hair extension, with citrus oil, separating the tape from the strip of polyurethane base support, and discarding the tape. A new rectangular strip of double-sided self-adhesive tape may be reapplied to the strip of polyurethane in order to reuse the hair extension. The strands of hair secured to the ventilated polyurethane strip as referenced earlier can be natural or synthetic and are also available in a variety of textures, colors and lengths.
The invention, therefore, resides not in any one of these features per se, but rather in the particular combination of all of them as herein disclosed. It is distinguished from the prior art in this particular combination of all of its structures for functions specified as follows: can be used on those wearers who have sensitive scalps; for those who just had a face lift performed wanting to disguise a receded hair line surgery has produced; for those wanting to achieve highlighted hair without use of damaging solutions; for those whose crown hair line has receded due to age or other factors; as well as for those wanting a temporary eyebrow lift which is achieved by simply disguising side temples of the hair line which in turn has receded due to age or other factors; or for those who simply desire longer and or thicker hair.
The foregoing has outlined rather broadly the more pertinent and important features of the present invention in order that a detailed description of the invention that follows may be better understood so that the present contribution to the art can be more fully appreciated. Additional features of the invention will be described hereinafter. It should be appreciated by those skilled in the art that conception and the disclosed specific method and structures may be readily utilized as a basis for modifying or designing other structures for obtaining the same purposes of the present invention. It should be realized by those skilled in the art that such equivalent methods and structures do not depart from the spirit and scope of the invention.
In this respect, before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to details of construction and to arrangements of components set forth in the following description or illustrated in the drawings. The invention is cable of other embodiments, and of being practiced and performed in various ways. Also, it is to be understood that phraseology and terminology employed herein are for a purpose of description and should not be regarded as limiting.
As such, those skilled in the art will appreciate that the conception, upon which this disclosure is based, may readily be utilized as a basis for designing of other structures, methods and systems for obtaining the several purposes of the present invention.
Accordingly, it is an object of the invention to provide an easy to use, comfortable to wear, and no tension caused to a scalp or a wearer's hair, reusable seamless self-adhesive hair extension.
A significant object of the invention is to provide a seamless self-adhesive hair extension that is comprised of a strip of polyurethane that has been ventilated with a quantity of parallel arranged natural or synthetic hair strands attached to one side of a strip of clear double face self-adhesive tape, which is then secured to hair of a wearer by another strip of clear double face self-adhesive tape which will encompass alternating parallel 1⁄4 sections of the wearer's own natural existing hair.
Another very significant object of the invention is to provide a seamless self-adhesive hair extension that provides an appearance of longer, thicker, and/or highlighted hair by overcoming disadvantages of conventional hair enhancing and supplementing devices and techniques, such as wigs, hair weaves and braids, and removable hair extensions and attachments.
A final but very important aspect of the invention is that it is virtually undetectable to the eye or touch, due to the hair being ventilated through a very thin but durable polyurethane layer and or strip, and then attached with a double face self-adhesive tape, thus making it easy to apply to the wearer's crown and or temples, if so desired.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring now to illustrations, and in particular to FIG. 1, wherein there is an actual view of a seamless self-adhesive hair extension 10. The hair extension 10 consists of a plurality of supplemental hair strands 12. The hair strands 12 are comprised of natural or synthetic supplemental hair in a variety of lengths, diameters, textures, and colors in order to accommodate desires and needs of a variety of wearers and fashion styles. A quantity of hair strands 12 is arranged generally or typically in a parallel arrangement so the strands 12 are aligned at a first attached end 18 and a second non-attached end 20.
Referring to FIG. 2, there is illustrated an exploded front or face view of a polyurethane strip 16 containing the attached end of the hair strands which are ventilated throughout the polyurethane strip 16.
In FIG. 3 is illustrated an exploded back view to reveal components and construction of a support polyurethane base or the polyurethane strip 16, with the hair strands 18 being ventilated through the polyurethane strip by virtue of knotting each supplemental hair strand 12, implanting the supplemental hair strands 12 through the polyurethane strip 16, and applying a coat of polyurethane thus sealing attached ends of the supplemental hair strands 12 to the polyurethane strip 16. The polyurethane strip 16 is comprised of flexible and durable material that conforms to a shape and contour of various scalps and scalp surfaces in order to achieve a comfortable and unobstructed fit thereon. A fastener 14 of double-sided self-adhesive tape is rectangular and preferably narrow and elongate in order to correspond with a perimeter of the polyurethane strip 16. The fastener 14 is comprised of a self-adhesive double-sided tape 22 and a removable backing 24. The self-adhesive double-sided tape 22 is secured to the polyurethane strip 16, in order to prevent the tape 22 from being separated or repositioned during use.
In FIG. 4 a back view or attachable view of the seamless self-adhesive hair extension system is illustrated with the removable backing 24 attached.
In FIG. 5 a process and method of attachment referred to as step 1 is illustrated, wherein a strip of Velcro 36 is used to secure and part an upper portion 32 and a lower portion 34, of a wearer's 28 hair, thus achieving a part line 30.
In FIG. 6 a process and method of attachment referred to as step 2 is illustrated, with the upper portion 32 and lower portion 34 being secured in an upward position by the Velcro 36, wherein a strip of double-sided self-adhesive tape 22 is placed onto the lower portion 34 of the wearer's hair 38 approximately 1⁄4′′ away from the wearer's scalp 44, and by using a crotchet needle 40 the wearer's natural hair strands 38 are withdrawn in approximately 1⁄4′′ alternating sections from the upper portion 32 and placed onto the double-sided self-adhesive tape 22, preferably an entire length of the self-adhesive double-sided tape 22.
In FIG. 7 a process and method of attachment referred to as step 3 is illustrated, wherein once the wearer's natural hair strands 38 are placed onto the double-sided self-adhesive tape 22 in alternating “A” sections preferably along the entire length of the self-adhesive double-sided tape 22, as described and illustrated previously in step 2 with reference to FIG. 7, the backing 24 can be removed and the seamless hair extension 10 can be adhered to the double-sided self-adhesive tape 22 on wearer 28. If necessary, the hair extension 10 can be cut or trimmed either vertically or horizontally to conform to an existing or proposed hair style or preference of the wearer. Once the hair extension 10 is secured and aligned onto the double-sided tape 22, the upper portion 32 of the hair can be dropped by removing the Velcro strip 36, and releasing the lower portion 34 via removing the Velcro strip 36 as well. Once the hair is in its original position it will conceal the self-adhesive tape 22 as well as the polyurethane strip 16 resulting in a seamless, lifelike natural appearance of longer, thicker and or highlighted hair. Of course the hair extension 10 can be attached to the head of the wearer 28 in a variety of styles and quantities and at an assortment of locations and positions thereon, with placement only limited by imagination of the wearer and hair dresser. It should be recognized that the example of attachment described previously by no means limits the spirit and the scope of the invention, and that all possible variations of attaching the seamless self-adhesive extension 10 to either the hair or scalp of a wearer remains within the purview of the instant invention.
