Title: Seamless hair extension method

Description:
BACKGROUND OF THE INVENTION 
     (1) Field of the Invention 
     The invention relates to the technical field of hair extension, and more particularly to a painless and seamless hair extension method capable of performing fast hair extension, so that the hair and the hair bundle can be bonded into one piece in a radial manner, that the long-time connection can be kept, that every bundle of hair is arbitrarily movable at the hair root, and that the arrangement can be conveniently performed. 
     (2) Description of the Prior Art 
     With the continuously improving living materials of the people as well as the fact that the beauty is the nature of people, the change in the hair style has naturally become an important issue of creating the beauty feeling. However, different persons have slightly different hair qualities, hair volumes and hair colors, the people&#39;s preferences on the long hair and short hair changes with time, and the people&#39;s preferences on the length or shape of the hair change with the different occasions, costumes, styles and mood. Thus, for the person having the short hair, the damaged cut hair or damaged dyed hair and wanting to have the long hair rapidly, using the hair extension technology to form the long hair based on the short hair has become a good choice. 
     At present, the common hair extension method in the industry is mainly based on the stitching type, patch type, tying type or buckle type. However, if the serially connected hair bundles are too close to the scalp or the serially connected angle leaves no space, then the native hair and the serially connected hair bundles are twitched to cause folliculitis. The above-mentioned hair extension method or appliance unavoidably encounters the ignoring angle and distance relationships with the scalp, thereby causing the hair root strain, and thus forming the folliculitis, scalp neuralgia and redness phenomena. Furthermore, the scalp cannot be completely cleaned, so the prior art is not suitable for the long-term serial connecting or sticking on the head. 
     In short, because there are numerous existing hair extension methods, the above-mentioned method is performed by the connection of one to one with the adhering connection. However, the connection state between the hairs tends to detach, and a lot of time is wasted. Meanwhile, the hairs cannot be easily arranged, or even the scalp disease is caused. So, how to solve this problem is an important subject in the current industry. 
     In view of this, the present inventor has made deep conceiving on the existing problems upon hair extension, and finally developed a seamless hair extension method capable of overcoming the existing inconvenience and trouble caused by the time-consuming and the easy detachment by actively seeking solutions according to years of experience in research and development and manufacturing of related industries together with the continuous research and trial work.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     The invention provides a seamless hair extension method. In the embodiments and the components illustrated in the accompanying drawings, all references to front and rear, left and right, top and bottom, upper and lower, and horizontal and vertical are provided for the convenience of description only without limiting the invention, and also do not intend to limit the components to any positional or spatial orientation. The dimensions specified in the drawings and the specification may be changed in accordance with the design and needs of the specific embodiments of the present invention without departing from the scope of the invention. 
     Referring to  FIG. 1 , the invention provides a seamless hair extension method capable of serially connecting a to-be-extended hair  20  to a bottom end of a native hair  10  in a painless and fast manner, so that the native hair  10  of the short hair can form the hair outlook of the long hair. The implementing steps of the seamless hair extension method of the invention are shown in  FIG. 2 , and include a native hair processing step S 01 , a to-be-extended hair processing step S 02 , an adhesive bonding step S 03 , a bundle bonding step S 04  and a trimming step S 05 . 
     In the native hair processing step S 01 , as shown in  FIGS. 1 to 3 , when the native hair  10  of a to-be-hair-extended person is the short hair, the operator can determine the hair quality information of the native hair  10 , such as the oiliness, thickness, hair color and the like, by an instrument for analyzing, by visual observation and or the like, and perform the essential front process, such as hair caring, dying or the like, according to the hair quality information of the native hair  10  and the style requirement. Then, as shown in  FIG. 3 , the portion of the native hair  10  close to a top of a head of the to-be-hair-extended person is defined as an upper region  101 , the portion of the native hair  10  close to the neck is defined as a lower region  102 , and the native hair  10  of the upper region  101  is put up, clamped and positioned as the top of the head to cover the connection portion between the native hair  10  of the lower region  102  and the to-be-extended hair  20 . In addition, the native hair  10  of the lower region  102  is combed and cut to be neat, and the hair is grouped evenly according to the hair quality information and the style requirement of the to-be-hair-extended person. Typically, native hair bundles  15  having the numbers ranging from about 50 to 115 are grouped, and each of the native hair bundles  15  includes hair lines having the number ranging from about 180 to 280. 
     In the to-be-extended hair processing step S 02 , as shown in  FIGS. 1 to 3 , the to-be-extended hair  20  having the hair quality, such as the oilness, thickness, hair color or the like, having approximate patterns similar to that of the native hair  10  of the to-be-hair-extended person is selected according to the hair quality information of the native hair  10  of the to-be-hair-extended person and a to-be-serially-connected length. The to-be-extended hair  20  is grouped into to-be-extended hair bundles  25  having the same number of bundles and the same size according to the bundle number and the size of the native hair  10 , and the to-be-extended hair  20  is grouped into the to-be-extended hair bundles  25  having the numbers ranging from about 50 to 115, wherein each of the to-be-extended hair bundles  25  includes hair lines having the number ranging from 180 to 280. In addition, the numbers of hair lines of the native hair bundle  15  of the native hair  10  and the to-be-extended hair bundle  25  of the to-be-extended hair  20  are controlled to prevent the hair lines from being broken due to the too few hair lines of each native hair bundle  15  and each to-be-extended hair bundle  25 , and the naturalness of the hair extension is also prevented from being affected due to the too many hair lines of each native hair bundle  15  and each to-be-extended hair bundle  25 . 
     In the adhesive bonding step S 03 , as shown in  FIGS. 4 and 5 , a rubber sleeve  40  made of a transparent plastic material is provided to cover each of the to-be-extended hair bundles  25  of the to-be-extended hair  20 , each of serial connection ends of the to-be-extended hair bundles  25  is correspondingly directed to one end of the native hair bundle  15  of the lower region  102  of the native hair  10 , and ends of the corresponding native hair bundles  15  and ends of the to-be-extended hair bundle  25  are mutually overlapped with and insertion-connected together in a radial manner. Then, a quick drying adhesive  35  is further added into the overlapped and insertion-connected region while rubbing and adhering are performed, so that a serial connection segment  30  is pre-formed between the native hair bundle  15  and the to-be-extended hair bundle  25 , and functions as a preliminary serial connection effect. After the quick drying adhesive  35  is dried, hot pressing on the serial connection segment  30  using a hot pressing bar, for example, is performed in an environment at a temperature ranging from 80° C. to 110° C., so that the quick drying adhesive  35  of the serial connection segment  30  can be hot pressed and adhered to the serial connection segment  30  between the native hair bundle  15  and the corresponding to-be-extended hair bundle  25 , and the adhesive bonding step of bonding each of the native hair bundles  15  and each of the to-be-extended hair bundles  25  is completed one by one. 
     In the bundle bonding step S 04 , as shown in  FIGS. 6 and 7 , the rubber sleeve  40  on each of the to-be-extended hair bundles  25  of the to-be-extended hair  20  is moved upward, and the rubber sleeve  40  covers the outside of the serial connection segment  30  between the native hair bundle  15  of the native hair  10  and the to-be-extended hair bundle  25  of the to-be-extended hair  20 . Then, the clamping is performed on the outside of the rubber sleeve  40  of each of the serial connection segments  30  in an environment at a temperature ranging from 90° C. to 120° C. by a hot pressing bar, for example, so that the rubber sleeve  40  can be melted to form a more transparent shape, and the bundle bonding step of each of the native hair bundles  15  and each of the to-be-extended hair bundles  25  can be completed. 
     In the trimming step S 05 , after the adhesive bonding step and the bundle bonding step are completed, each of the to-be-extended hair bundles  25  of the to-be-extended hair  20  is correspondingly and serially connected to the distal end of each of the native hair bundles  15  of the native hair  10 , and then the upper region  101  of the native hair  10  is put down to just cover the native hair  10  of the lower region  102  and the serial connection segment  30  of the to-be-extended hair  20 , and finally perming and dying are performed according to the requirement style of the to-be-hair-extended person to make the hairstyles and colors of the native hair  10  and the to-be-extended hair  20  have the correspondence. Then, trimming is performed to form the suitable style and to form the long hair style shown in  FIG. 8 . 
     With the above-mentioned design, the seamless hair extension method of the invention can utilize the bundle dividing preparations of the native hair  10  and the to-be-extended hair  20 , and utilize the adhering of the adhesive bonding step and the bonding of the bundle bonding step to complete the overall hair extension process quickly, so that the hair extension step and time can be shortened, a hair extension effect is firm, and the hair cannot easily fall off. 
     Furthermore, because the native hair  10  and the to-be-extended hair  20  serially connect the native hair bundle  15  and the to-be-extended hair bundle  25  into one piece in a radial manner, every bundle of hair is arbitrarily movable at a hair root, no discomfort pain is caused by the long time of usage, and the hair can be conveniently arranged. 
     Meanwhile, every corner of the scalp can be sufficiently cleaned, the scalp disease cannot be caused, and the personal scalp health can be promoted. 
     Moreover, every bundle of hair is movable at the hair root in directions at 360 degrees, the hair can be conveniently arranged, and a more natural and diverse hair shape can be created to enhance the overall beauty of the individual person. 
     In summary, it is possible to understand that the invention is an innovative creation, and that the invention can effectively solve the conventional problems and further significantly enhance the effects.
