Description

[Technical field]

[0001] The present invention relates to artificial hair for hair augmentation and a hair augmentation method, and more particularly to artificial hair for augmenting human hair and a hair augmentation method. [Background technology]

[0002] A hair-adding method for natural hair growing on the head that does not require tying the natural hair to the hair for hair addition, has been known in the past that allows the knot to be small and the hair for hair addition to be strongly fixed to the natural hair (Patent Document 1). When tying the hair for hair addition to the natural hair, the natural hair is passed through overlapping loops, and the loops are reduced in size by pulling the first and second ends extending from the loops in opposite directions.

[0003] Another hair-adding method uses a hair-adding tool with a tweezers-shaped hair-clamping part capable of clamping multiple hairs for hair addition (Patent Document 2). When adding hair, the natural hair is clamped with the tweezers, and the hair for hair addition clamped in the hair-adding clamping part is moved to pass the natural hair through the loop. The hair for hair addition is moved to the root of the natural hair, and the hair extending from the loop is pulled in opposite directions to tie the hair for hair addition to the natural hair.

[0004] [Patent Document 1] JP 2023-23892 A [Patent Document 2] JP 2006-152486 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the hair-adding methods described in Patent Documents 1 and 2, the hair for hair-adding is selected to have a color, thickness, and texture close to the natural hair in order to naturally increase the volume of the hair, so that it becomes difficult to distinguish between the natural hair, the first end, and the second end during the hair-adding treatment. In particular, when using hair for hair-adding with a large amount of hair, such as 6 or 10 hairs, the amount of hair bundles at the first end and the second end increases, causing the ends of the hair for hair-adding to spread, making it more difficult to distinguish between the first end and the second end. This causes a problem that when the hair for hair-adding is tied to the natural hair during the hair-adding treatment, the wrong hair is pulled, and the loop does not shrink.

[0006] Although the handling of hair for hair growth with a large amount of hair enables efficient hair growth by fastening to natural hair once, the hair for hair growth is difficult to handle. In light of this background, there has been a demand for a hair growth method that allows easy and efficient hair growth treatment even for hair for hair growth with a large amount of hair.

[0007] Therefore, an object of the present invention is to provide artificial hair for hair increase and a hair increase method that enable efficient hair increase treatment. [Means for solving the problem]

[0008] In order to solve the above problems, the present invention provides a hair augmentation method comprising the steps of: tying at least one artificial hair to form a loop, thereby extending a first end and a second end from the loop; attaching a holding part to at least one of the first end and the second end, which is held during hair augmentation treatment, so that the holding part can be moved over the artificial hair; threading natural hair through the loop; moving the loop to the base of the natural hair; pulling the holding part and at least one of the first end and the second end in opposite directions to shrink the loop and tie the artificial hair to the natural hair; and moving the holding part to remove the holding part from at least one of the first end and the second end to which the holding part is tied.

[0009] Furthermore, it is preferable that the step of threading the natural hair through the loop comprises the steps of: passing the loop through tweezers; shrinking the loop by pulling at least two of the first end, the second end, or the holding portion; and, while holding the natural hair with the tweezers, moving the loop from above the tweezers to separate the loop from the tweezers, thereby threading the natural hair through the loop.

[0010] It is also preferable that at least a portion of the artificial hair maintains the curved shape of the loop even after the loop is contracted.

[0011] According to another aspect of the present invention, there is provided a hair augmentation method comprising the steps of: tying at least one artificial hair to form a loop, thereby extending a first end and a second end from the loop; applying heat to the loop to create a curved curl; attaching a gripping portion to at least one of the first end and the second end during hair augmentation treatment so that the gripping portion can be moved over the artificial hair; threading natural hair through the loop; moving the loop to the base of the natural hair; pulling the gripping portion and at least one of the first end and the second end in different directions to shrink the loop and tie the artificial hair to the natural hair; moving the gripping portion to remove the gripping portion from at least one of the first end and the second end to which the gripping portion is tied; and cutting the artificial hair while leaving at least a portion of the curl remaining.

[0012] According to another aspect of the present invention, there is provided an artificial hair for hair augmentation, which comprises at least one artificial hair having a first end and a second end, which is tied to form a loop so that the first end and the second end extend from the loop, and a gripping portion that is gripped during hair augmentation treatment is movably attached to at least one of the first end and the second end.

[0013] Furthermore, when the loop is shrunk and tied to natural hair by pulling at least one of the first end and the second end and the gripping portion in different directions, it is preferable that at least a portion of the portion that constituted the loop retains the curved shape of the loop even after being shrunk. Effect of the Invention

[0014] According to this configuration, since the artificial hair is tied to the natural hair by pulling the gripping portion and the first and second ends in opposite directions, it is easier to determine which hair should be pulled compared to the case where the artificial hairs are pulled in opposite directions. This prevents the first end, the second end, and the natural hair from being mixed together, making it difficult to determine which hair should be pulled during the tying work, and makes the hair-adding treatment more efficient. In addition, since the artificial hair is tied to the natural hair by pulling the gripping portion located at the base of the loop, it is possible to pull the loop with a strong force and make the knot smaller. This makes it possible to realize hair-adding that is easy to comb. Since the gripping portion can move on the artificial hair, it is possible to remove the gripping portion after treatment to eliminate any influence on the appearance of the hair-adding. In addition, since the artificial hair is tied to the natural hair by moving the loop to the base, the effect of hair-adding can be obtained for a long period of time even if the hair grows.

[0015] According to this configuration, the loop is contracted and the tweezers are moved to pass the natural hair through the loop, so that the loop is prevented from coming off the tweezers. This makes it possible to perform hair-augmentation treatment efficiently. In addition, the natural hair is held by the tweezers and the loop is moved to pass the natural hair through the loop, so that the natural hair can be passed through the loop in a simple manner.

[0016] According to this configuration, at least a part of the artificial hair maintains the curved shape of the loop, so that it remains curved even after being tied to the natural hair. This allows the natural hair to stand up due to the curved artificial hair, increasing the volume of the hair. This makes it possible to efficiently increase the volume of hair using natural hair.

[0017] According to this configuration, the curled portion is created by applying heat to the loop of the artificial hair, so the curved state of the curled portion can be maintained for a long period of time. This allows the natural hair to be kept standing by the curved artificial hair for a long period of time. In addition, since the artificial hair is cut while leaving at least a part of the curled portion, the natural hair can be made to stand by the curved artificial hair, increasing the volume of the hair.

[0018] With this configuration, the gripping part bundles the multiple hairs at the first end and the second end, making it easier to gather the artificial hair and preventing the hairs at the first end and the second end from becoming entangled. This makes it possible to identify the hairs to be pulled when tying the artificial hair to the natural hair, enabling efficient hair-augmentation treatment.

[0019] With this configuration, the partially curved shape is maintained even after the loop is contracted, so the artificial hair remains curved even after it is tied to the natural hair. This allows the artificial hair to stand up the natural hair, increasing the volume of the hair.

[0020] According to the present invention, it is possible to provide artificial hair for hair increase and a hair increase method that enable efficient hair increase treatment. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0022] An artificial hair 1 according to a first embodiment of the present invention will be described with reference to Figs. 1 to 6. As shown in the figures, up, down, left and right directions are defined. As shown in Fig. 1, the artificial hair 1 for hair augmentation is formed by tying at least one artificial hair having one end and the other end by a known method to form a loop 4 from which a first end 2 including the one end and a second end 3 including the other end extend. A string-like gripping part 5 of a different color and material from the artificial hair 1 is tied to the second end 3. The gripping part 5 may be tied to either the first end 2 or the second end 3, but the second end 3 located on the right side is preferable. The gripping part 5 is held by the practitioner when tying the artificial hair 1 to the natural hair 10.

[0023] The artificial hair 1 is made of materials such as polyester, acrylic, polyamide, PVC, nylon, etc., but is not limited to these and can be made of materials with a texture similar to that of human hair. The gripping part 5 is preferably string-shaped and made of a material different from that of the artificial hair 1, and can be made of cotton, silk, rayon, polyester, nylon, wool, hemp, etc.

[0024] When tying the string-like gripping part 5 to the second end 3 of the artificial hair 1, it is tied with a Lark's Head knot as shown in Fig. 2. Specifically, as shown in Fig. 2(a), the gripping part 5 having one end 51 and the other end 52 is placed near the second end 3. As shown in Figs. 2(b) and 2(c), the one end 51 and the other end 52 are passed from above the second end 3 into the space W defined by overlapping the second end 3 and the gripping part 5.

[0025] As shown in Fig. 2(d), one end 51 and the other end 52 are pulled to eliminate the space W and tie the gripping part 5 to the second end 3. As shown in Figs. 2(e) and 2(f), the gripping part 5 is moved and placed near the loop 4. Note that the method of tying the gripping part 5 to the artificial hair 1 can be any method other than the above-mentioned Lark's Head knot. In this case, it is preferable that the knotting method be one that allows the gripping part 5 to move smoothly along the artificial hair 1.

[0026] As shown in FIG. 3, when the amount of artificial hair 1 is large, tying the gripping part 5 to the second end 3 bundles the artificial hair 1 together, improving workability. In order to increase the work efficiency of one hair-adding treatment, artificial hair 1 with a large amount of hair is required, but as the amount of hair increases, the hair bundles at the first end 2 and the second end 3 become mixed together, deteriorating workability. However, by tying the gripping part 5 near the loop 4, the hair bundles at the second end 3 are bundled together, making it easier to distinguish them from the hair bundles at the first end 2, and hair-adding treatment can be performed efficiently. In particular, when the first end 2 and the second end 3 each have three or more strands and the artificial hair 1 has six or more strands, a remarkable effect is obtained. According to this embodiment, even if the artificial hair 1 has ten or more strands, smooth hair-adding treatment is possible.

[0027] 4 and 5, a process of hair-augmentation treatment in which the practitioner connects the artificial hair 1 to the natural hair 10 will be described. Tweezers 20 are used for the hair-augmentation treatment, but the tool used is not limited to this and any tool capable of clamping hair may be used.

[0028] As shown in FIG. 4(a), with the loop 4 of the artificial hair 1 passed through the tweezers 20, the natural hair 10 is clamped with the tweezers 20. As shown by the arrow in FIG. 4(a), the practitioner holds the gripping portion 5 with one hand and holds the first end 2 and the second end 3 with the other hand and pulls them to the right. As a result, as shown in FIG. 4(b), the practitioner shrinks the loop 4 of the artificial hair 1 while it is passed through the tweezers 20. This makes it possible to prevent the loop 4 from moving inadvertently on the tweezers 20. The loop 4 may also be shrinked by pulling the first end 2 and the second end 3 in opposite directions.

[0029] As shown by the arrows in Fig. 4(b), the practitioner moves the tweezers 20 in a lower right direction and moves the loop 4 in an upper left direction to separate the artificial hair 1 from the tweezers 20. This allows the natural hair 10 to be passed through the loop 4 as shown in Fig. 4(c). As shown in Fig. 4(d), the practitioner moves the loop 4 to the root of the natural hair 10. At this time, the natural hair 10 may be locked with a stopper (not shown) to prevent the natural hair 10 from coming off the loop 4.

[0030] 5(e) and 5(f), with the loop 4 positioned near the base of the natural hair 10, the practitioner pulls the gripping portion 5 leftward and the first end 2 and the second end 3 rightward to tie the artificial hair 1 to the base of the natural hair 10. In other words, the practitioner pulls the gripping portion 5 and the first end 2 and the second end 3 in opposite directions to tie the artificial hair 1 to the natural hair 10.

[0031] As shown in Figures 5(g) and 5(h), the practitioner pulls the gripping part 5 to the right and slides it over the second end 3, and removes the gripping part 5 from the artificial hair 1. Finally, the practitioner cuts the first end 2 and the second end 3 with a cutter (not shown) to match the length of the natural hair 10. This completes the hair-augmenting treatment of the artificial hair 1 to the natural hair 10.

[0032] A conventional hair-augmenting treatment and a hair-augmenting treatment according to the present embodiment will be compared with each other with reference to FIG. 6. In the conventional hair-augmenting treatment, as shown in FIG. 6(a), when tying the artificial hair 101 to the natural hair 10, the practitioner pulls the first end 102 extending from the loop 104 of the artificial hair 101 and the second end 103 extending from the loop 104 of the artificial hair 101 in opposite directions to shrink the loop 104. In contrast, in the present invention, as shown in FIG. 6(b), when tying the artificial hair 1 to the natural hair 10, the practitioner pulls the gripping portion 5 and the first and second ends 2 and 3 in opposite directions to shrink the loop 4. This allows the artificial hair 1 to be tied with a stronger force by pulling the gripping portion 5 located at the base of the natural hair 10, and thus prevents the artificial hair 1 from coming off.

[0033] According to this configuration, the artificial hair 1 is tied to the natural hair 10 by pulling the gripping part 5 and the first end 2 and the second end 3 in opposite directions, so that it is easier to determine which hair should be pulled compared to the case where the artificial hairs 1 are pulled in opposite directions. This prevents the first end 2, the second end 3, and the natural hair 10 from being mixed together, making it difficult to determine which hair should be pulled during the tying work, and makes the hair-adding treatment more efficient. In addition, the artificial hair 1 is tied to the natural hair 10 by pulling the gripping part 5, so that the knot can be made small. This makes it possible to achieve hair-adding that is easy to comb. Since the gripping part 5 can move on the artificial hair 1, the gripping part 5 can be removed after the treatment to eliminate any influence on the appearance of the hair-adding. In addition, since the loop 4 is moved to the root of the natural hair 10 to tie the artificial hair 1 to the natural hair 10, the effect of hair-adding can be obtained for a long period of time even if the hair grows.

[0034] According to this configuration, the tweezers 20 are moved while the loop 4 is contracted to pass the natural hair 10 through the loop 4, so that the loop 4 can be prevented from coming off the tweezers 20. This allows for efficient hair-augmentation treatment. In addition, the natural hair 10 can be passed through the loop 4 by moving the loop 4 while the natural hair 10 is held by the tweezers 20, so that the natural hair 10 can be passed through the loop 4 in a simple manner.

[0035] With this configuration, the gripping portion 5 bundles the multiple hairs at the first end 2 and the second end 3, making it easier to gather the artificial hair 1 and preventing the hairs at the first end 2 and the second end 3 from entangling. This makes it possible to identify the hairs to be pulled when tying the artificial hair 1 to the natural hair 10, enabling efficient hair-augmentation treatment.

[0036] Next, a second embodiment of the present invention will be described with reference to Figures 7 and 8. The same components as those in the first embodiment are given the same reference numerals and the description thereof will be omitted.

[0037] In the artificial hair 201 according to the second embodiment, a string-like first gripping part 205 is tied to the first end 2, and a string-like second gripping part 206 is tied to the second end 3. The first gripping part 205 and the second gripping part 206 are desirably tied in a Lark's Head knot, similar to the first embodiment. This allows the hair bundle at the first end 2 and the hair bundle at the second end 3 to be clearly distinguished, thereby improving the efficiency of the hair-augmentation treatment.

[0038] When tying the artificial hair 201 to the natural hair 10, the first gripping part 205 is pulled leftward and the second gripping part 206 is pulled rightward, as shown in Fig. 8. After that, the first gripping part 205 is pulled leftward to move it over the first end part 2, and the second gripping part 206 is pulled rightward to move it over the second end part 3, thereby separating the artificial hair 201 from the first gripping part 205 and the second gripping part 206.

[0039] Next, a third embodiment of the present invention will be described with reference to Figures 11 to 13. The same components as those in the first embodiment are given the same reference numerals and the description thereof will be omitted.

[0040] The artificial hair 401 for hair augmentation is formed by tying at least one artificial hair having one end and the other end by a known method, to form a loop 404 from which a first end 402 including the one end and a second end 403 including the other end extend. The artificial hair 401 has a larger diameter of the loop 404 and a larger number of turns of the loop 404 compared to the artificial hair 1 of the first embodiment. The loop 404 of the artificial hair 401 can maintain a shape in which the curled portion 404A, which is the artificial hair 401 constituting the loop 404, is curved into a substantially circular shape for a long period of time by applying heat. In other words, the curled portion 404A is a portion of the artificial hair 401 constituting the loop 404, and has a shape in which multiple circles are connected like a spring. The method for maintaining the shape of the curled portion 404A is not limited to heat, and the curved shape may be maintained by a chemical or the like.

[0041] The gripping part 5 may be tied to either the first end 402 or the second end 403, but the second end 403 located on the right side is preferable. The gripping part 5 is held by the practitioner when tying the artificial hair 401 to the natural hair 10. The gripping part 5 is preferably tied to a Lark's Head knot as in the first embodiment, but is not limited to this and can be tied in any manner.

[0042] 12 and 13, a hair-augmenting treatment in which the practitioner ties the artificial hair 401 to the natural hair 10 will be described. Tweezers 20 are used for the hair-augmenting treatment, but the tool used is not limited to this and any tool capable of clamping hair may be used.

[0043] As shown in FIG. 12(a), the practitioner holds the natural hair 10 with the tweezers 20 while passing the loop 4 of the artificial hair 401 through the tweezers 20. At this time, the natural hair 10 may be locked by a stopper (not shown) to stabilize the position of the natural hair 10 and improve workability. As shown by the arrow in FIG. 12(a), the practitioner holds the tweezers 20 with one hand and holds the first end 402 and the second end 403 with the other hand and pulls them to the right, so that the loop 4 of the artificial hair 401 shrinks while passing through the tweezers 20, as shown in FIG. 12(b). This makes it possible to prevent the loop 4 from moving inadvertently on the tweezers 20. The practitioner may also shrink the loop 404 by pulling the first end 402 and the second end 403 in opposite directions. At this time, since the curled portion 404A becomes substantially spring-shaped, the connection portion between the first end 402 and the second end 403 and the loop 404 becomes a shape of a continuous series of circles. The gripping portion 5 is located at a position separated from the loop 404 to the right, and the artificial hair 401 between the gripping portion 5 and the loop 404 becomes the curled portion 404A. Since the curled portion 404A is deformed into a substantially spring shape, the first end 402 and the second end 403 tend to be mixed together, making it difficult to handle the artificial hair 401. However, since the gripping portion 5 is provided at the second end 403, it is easy to distinguish the hair bundle on the first end 402 side from the hair bundle on the second end 403 side.

[0044] As shown by the arrow in FIG. 12(b), the practitioner moves the tweezers 20 in a lower right direction and also moves the loop 4 to separate the tweezers 20 from the loop 404 of the artificial hair 401. This allows the natural hair 10 to be passed through the loop 4 as shown in FIG. 12(c). As shown in FIG. 12(d), the practitioner slides the gripping part 5 over the artificial hair 401 until it approaches the loop 404 while holding the first end 402 and the second end 403 with one hand. At this time, by moving the gripping part 5 while simultaneously pulling the first end 402 and the second end 403 to the right, the loop 404 is further reduced and is tied to the natural hair 10 with enough firmness to be able to move it thereto.

[0045] As shown in FIG. 13(e), the practitioner holds the gripping portion 5 with the tweezers 20, holds the natural hair 10 with the other hand, and moves the artificial hair 401 to the root of the natural hair 10. As shown in FIG. 13(f), in order to fix the artificial hair 401 to the natural hair 10, the practitioner pulls the gripping portion 5 to the left and pulls the first end 402 and the second end 403 to the right. At this time, the first end 402 and the second end 403 are mixed together, so it may be unclear which artificial hair 401 belongs to which end. In particular, since the artificial hair 401 has a curled portion 404A, the artificial hair 401 is easily tangled and difficult to handle. However, by holding the gripping portion 5 provided on the second end 403 with the tweezers 20, the artificial hair 401 on the first end 402 side and the artificial hair 401 on the second end 403 side can be easily distinguished. Furthermore, even if the first end 402 and the second end 403 are mixed as shown in Figure 13 (f), by pulling the gripping portion 5 to the left and the first end 402 and the second end 403 to the right, it is possible to shrink the loop 404 and tie the artificial hair 401 to the root of the natural hair 10.

[0046] As shown in FIG. 13(g), the practitioner pulls the gripping part 5 to the right and slides it over the second end 403 to remove the gripping part 5 from the artificial hair 401, and cuts the first end 402 and the second end 403 of the artificial hair 401 along a dashed line with the cutter 410, leaving the curled part 404A. As a result, as shown in FIG. 13(h), only the part of the artificial hair 401 that corresponds to the curled part 404A is tied to the natural hair 10. Then, the curved shape of the curled part 404A makes the natural hair 10 stand up, which increases the sense of volume of the entire head and allows hair growth using the artificial hair 401. This completes the hair growth treatment of the artificial hair 401 to the natural hair 10.

[0047] As shown in FIG. 14(a), conventional artificial hair 101 does not have curled parts 404A and is generally straight, so that the natural hair 10 falls flat and it is not possible to achieve the desired height. As a result, although the number of hairs increases with hair-augmenting treatment, it is difficult to achieve a sense of volume in the entire hair. In contrast, artificial hair 401 of the present embodiment, as shown in FIG. 14(b), has curled parts 404A that are generally spring-shaped, so that the artificial hairs 401 interfere with each other and are lifted upward, causing the roots of the natural hair 10 to stand up. As a result, the natural hair 10 stands up from the roots, efficiently achieving a sense of volume in the entire hair.

[0048] With this configuration, at least a part of the artificial hair 401 is the curled portion 404A that maintains the curved shape of the loop 404, so that the artificial hair 401 remains curved even after being tied to the natural hair 10. This allows the natural hair 10 to stand up due to the curved curled portion 404A, increasing the sense of volume of the hair. This makes it possible to efficiently increase the volume of hair using the natural hair 10.

[0049] With this configuration, the curled portion 404A is created by applying heat to the loop 404 of the artificial hair 401, so the curved state of the curled portion 404A can be maintained for a long period of time. This allows the natural hair 10 to be kept standing by the curved curled portion 404A for a long period of time. In addition, since the artificial hair 401 is cut while leaving at least a part of the curled portion 404A, the natural hair 10 can be made to stand by the curved curled portion 404A, increasing the sense of volume of the hair.

[0050] The artificial hair and hair-growth method according to the present invention are not limited to the above-described embodiment, and various modifications are possible within the scope of the gist of the invention described in the claims.

[0051] In the above-mentioned embodiment, the gripping part is string-shaped, but is not limited thereto. For example, it may be made of resin or silicon and be in the form of a tape as shown in FIG. 9. When attaching the gripping part 305 to the artificial hair 301, as shown in FIG. 10, the gripping part 305 is folded with the artificial hair 301 placed inside, and the attachment part 305a is attached to bond them together. Since the attachment part 305a is provided only on a part of the gripping part 305, the gripping part 305 can move on the second end 3 in the folded state. The gripping part 305 may be provided on both the first end 2 and the second end 3.

[0052] In the above embodiment, the loop 4 is contracted by pulling the gripping portion 5 and the first end 2 and the second end 3 in opposite directions to tie the artificial hair 1 to the natural hair 10, but this is not limiting. For example, the loop 4 may be contracted by pulling the gripping portion 5 and at least one of the first end 2 and the second end 3 in opposite directions. This allows the loop 4 to be contracted by pulling the gripping portion 5 and the remaining artificial hair 1, improving workability. [Explanation of symbols]
