Problems to be Solved by the Invention

[0005] In the "Hair Growth Method" of Patent Document 1, when attaching artificial hair (hair material), a knot is provided in a portion of natural hair near the scalp, and the artificial hair (hair material) is wound around this knot to function as a retaining means. The operation of making a knot in this natural hair was a complicated operation. In addition, there was a problem that the operation of making a knot required a long time.

Effects of the Invention

By applying the irradiation light in the visible region or the irradiation light of ultraviolet rays of this LED (light emitting diode), it can be cured faster than when it cures naturally. The hair augmentation operation can be completed in less than half the time compared to the conventional natural curing. Since the hair material (AH) is sandwiched and fixed between the first staple part (1) and the second staple part (2), the fixing position on the natural hair (H) does not shift, and it does not easily come off from the natural hair (H). The hair augmentation treatment can be safely performed.

[0016] In the first aspect of the present invention, since the photocuring adhesive is not directly applied to the part where the hair material (AH) is wound around the natural hair (H), even after the first staple part (1) and the second staple part (2) made of the photocuring adhesive are cured, the correction process of the hair material (AH) becomes possible. For example, the position where the hair material (AH) is tightened can be corrected, or when the tightening force of the hair material (AH) is loose, it can be tightened again. Also, when the hair material (AH) is damaged, it can be easily replaced.

Mode for Carrying Out the Invention

[0020] The method for attaching a hair material using the photocurable adhesive of the present invention is a method of forming a first staple portion that functions as a "retention" at a position close to the scalp of the natural hair with the photocurable adhesive, and winding the hair material between this first staple portion and the scalp.

Example

[0021] Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. <Configuration for directly clamping the hair material to the natural hair> FIG. 1 is an explanatory diagram showing the working procedure of Example 1. (a) shows the state of the natural hair before processing, (b) shows the state where the first staple portion is formed on the natural hair, (c) shows the state where the hair material is wound around the natural hair, (d) shows the state where the hair material is clamped to the natural hair, (e) shows the state where the second staple portion is formed on the natural hair, and (f) shows the state where the second staple portion is cured. FIG. 2 is a flowchart showing the working procedure of Example 1. In the illustrated example, only one natural hair is shown, but it is not limited to one and may be a plurality. Similarly, only one hair material is shown, but it is not limited to one and may be a plurality. The method of attaching the hair material in Example 1 is a hair growth method in which the hair material AH is wound around the natural hair H and fixed to a person's hair. On the natural hair H (Fig. 1(a)) of the person whose hair is to be grown, the first stud portion 1 is formed with a photocuring adhesive (Fig. 1(b)). When curing the photocuring adhesive, the irradiation light of an LED (light emitting diode) is applied. By applying the irradiation light in the visible region or the ultraviolet irradiation light of this LED (light emitting diode), it can be cured faster than when it cures naturally.

[0022] This first stud portion 1 functions as a "preventer from falling out" at a position close to the scalp S of the natural hair H. The outer diameter of the first stud portion 1 only needs to be longer than the diameter of the natural hair H. If the first stud portion 1 is too large, the adhesive is likely to adhere to adjacent natural hairs. Therefore, a length of about 2 to 3 times the diameter of the natural hair H is sufficient. In the illustrated example, the shape of the first stud portion 1 is shown as a spherical shape, but it is not necessary to make it an exact spherical shape, and any shape that functions as a "preventer from falling out" is acceptable. Therefore, it can be made into various shapes such as a drop shape or an ellipsoid (prolate spheroid) shape like a rugby ball.

[0023] Next, when winding the hair material AH around this natural hair H, the first stud portion 1 makes it difficult for the hair material AH to come off, and the hair material AH can be wound quickly. Moreover, since the first stud portion 1 that functions as a "preventer from falling out" uses a photocuring adhesive, it cures within a few seconds after being applied to the natural hair H. The next operation can proceed efficiently.

[0024] Finally, continuously to the knot portion K where the hair material AH is wound around the natural hair H, a second stud portion 2 is formed with a photocuring adhesive. This second stud portion 2 sandwiches the wound knot portion K together with the first stud portion 1 and functions as a "positioner". Regarding this second stud portion 2 as well, any shape that functions as a "positioner" is acceptable, so it is not limited to a spherical shape and can be made into various shapes such as a drop shape or an ellipsoid (prolate spheroid) shape.

[0025] Note that this second stud portion 2 does not necessarily need to be formed on the natural hair H. In the case of simple hair growth, only the "preventer from falling out" of the first stud portion 1 can also tighten and fix the natural hair H.

[0026] The second staple portion 2 also uses a photocuring adhesive, and when curing it, the irradiation light of an LED (light-emitting diode) is applied. Similar to the first staple portion 1, the irradiation light in the visible region or the irradiation light of ultraviolet rays of this LED (light-emitting diode) is applied, and it can be cured faster than when naturally cured. The hair growth operation can be completed in less than half the time compared to the conventional natural curing.

[0027] Since the knot portion K of the hair material AH is sandwiched and fixed between the first staple portion 1 and the second staple portion 2, the fixing position on the natural hair H does not shift or come off easily from the natural hair H. The person who receives the hair growth treatment can perform the hair growth treatment with confidence. When there is only the first staple portion 1, it functions as an "anti-slip".

[0028] The photocuring adhesive used in the present invention may be either an ultraviolet curing type or a visible light curing type. For example, there are acrylic adhesives or epoxy adhesives. As the photocuring adhesive, a room temperature curing type adhesive that reacts highly sensitively to the wavelength region generated by each light irradiation device and polymerizes and cures is used. Also, in order to cope with various adhesion structures, it is also possible to use an adhesive whose curing mechanism is a composite curing by ultraviolet rays and anaerobic, or visible light and ultraviolet rays.

[0029] <Example 1 of correction of hair material position> FIG. 3 is an explanatory diagram showing a state of correcting the position where the hair material is tightened, (a) is the state before correction, and (b) is the state after correction. In the method of attaching the hair material of Example 1, the photocuring adhesive (the first staple portion 1, the second staple portion 2) is not directly applied to the knotted portion K where the hair material AH is wound around the natural hair H. Even after these first staple portion 1 and second staple portion 2 are cured, the correction process of the hair material AH becomes possible. For example, the position where the hair material AH is tightened can be corrected from the position in FIG. 3(a) to the position in FIG. 3(b). When the tightening force of the hair material AH is loose, it can be tightened again, and when there is damage to the hair material AH, it can be easily replaced.

[0030] <Example 2 of correction of hair material position> FIG. 4 is an explanatory view showing a state of correcting the position for clamping the hair material when the natural hair grows. (a) shows the state before the growth of the hair, (b) shows the state after the growth of the hair and before the correction, and (c) shows the state after the correction. As the natural hair H grows, the position of the hair material AH moves away from the scalp S. Therefore, the second staple portion 2 is removed with a remover, and the knot portion K of the hair material AH is moved so as to approach the scalp S. Then, a new third staple portion 3 is formed on the natural hair H with a photocuring adhesive so that the knot portion K comes off. A fourth staple portion 4 is formed with a photocuring adhesive so as to sandwich the knot portion K with this third staple portion 3. Thereby, the position of the knotted portion K wound around the hair material AH can be moved close to the scalp S. Note that the first staple portion 1 may leave the natural hair H as it is, or may be removed with a remover.

[0031] <Modification Example of Example 1> FIG. 5 shows the working procedure of the modification example of Example 1. (a) shows the state in which a loop portion is made in the hair material, (b) shows the state in which the first staple portion is formed on the natural hair, (c) shows the state in which the loop portion of the hair material is passed through the natural hair, (d) shows the state in which the loop portion of the hair material is clamped on the natural hair, (e) shows the state in which the second staple portion is formed on the natural hair, and (f) shows the state in which the second staple portion is cured. FIG. 6 is a flowchart showing the working procedure of the modification example of Example 1. Note that the illustration is omitted because the procedure is substantially the same as that of Example 1 except for the procedure of previously forming the loop portion L in the hair material AH. In the method of Example 1 described above, the hair material AH is wound around the first staple portion 1 of the natural hair H and then clamped and fixed. In this modification example of Example 1, a method is adopted in which the loop portion L is previously formed in the knot portion K of the hair material AH. It is not necessary to perform the clamping of the hair material AH after hooking the hair material AH on the first staple portion 1. The loop portion L that will be clamped in advance is formed in the hair material AH and placed. With this configuration, the fixing operation of the hair material AH can be completed in a short time.

[0032] Also in this modification example of Example 1, as shown in FIG. 5(b), when curing the photocuring adhesive of the first staple portion 1 on the natural hair H, the irradiation light of the LED (light emitting diode) is applied. Further, as shown in FIG. 5(f), when curing the photocuring adhesive of the second staple portion 2, the irradiation light of the LED is also applied.

Example

[0033] <Configuration of directly clamping the hair material to the natural hair> FIG. 7 is an explanatory diagram showing the working procedure of Example 2, where (a) is the state of the natural hair before treatment, (b) is the state where the tubular member is attached to the hair material, (c) is the state where the first staple portion is formed on the natural hair, (d) is the state where the tubular member is inserted into the natural hair, (e) is the state where the tubular member is passed through the first staple portion to form the second staple portion, and (f) is the state where the second staple portion is cured. FIG. 8 is a flowchart showing the working procedure of Example 2. In addition, in the illustrated example, only one natural hair is shown, but it is not limited to one and may be a plurality of natural hairs. The method of attaching the hair material in Example 2 is a hair growth method of fixing the hair material AH to a person's hair by hooking it on the natural hair H using a tubular member 5 called a chip. The working procedure of Example 2 is substantially the same as that of Example 1 except for using the tubular member 5.

[0034] First, prepare a tubular member 5 made of metal or plastic with a plurality of hair materials AH attached thereto (FIG. 7(b)). Regarding a person's natural hair H, as in Example 1, the first staple portion 1 that functions as a "retention" is formed with a photocurable adhesive (FIG. 7(c)). When curing this first staple portion 1, the irradiation light of an LED (light-emitting diode) is applied. The outer diameter of the first staple portion 1 is formed shorter than that of the tubular member 5. This is for passing the tubular member 5 through the first staple portion 1 (FIG. 7(d)). Also in Example 2, the shape of the first staple portion 1 is not limited to a spherical shape and can be various shapes such as a droplet shape and an ellipsoid (prolate spheroid) shape.

[0035] Next, when hooking the tubular member 5 of the hair material AH on this natural hair H, since the first staple portion 1 is formed on the natural hair H also in the method of attaching the hair material in Example 2, it is difficult for the tubular member 5 to come off (FIG. 5(e)). Moreover, since the first staple portion 1 that functions as a "retention prevention" uses a photocurable adhesive, it cures within several seconds immediately after being applied to the natural hair. The next operation can proceed efficiently.

[0036] Finally, continuously with the portion where the tubular member 5 is hooked to the natural hair H, the second stud portion 2 is formed of a photocuring adhesive. The second stud portion 2 is cured by irradiating it with the irradiation light of an LED (light-emitting diode) (Fig. 7(f)). This second stud portion 2 sandwiches the tubular member 5 together with the first stud portion 1 and functions as "positioning". As described above, the second stud portion 2 can have various shapes as long as it functions as "positioning". In addition, also in the method of attaching the hair material of Example 2, it is not always necessary to form this second stud portion 2 on the natural hair H. In the case of simple hair augmentation, the natural hair can be tightened and fixed only by the "anti-slip" of the first stud portion 1. Since the tubular member 5 is sandwiched and fixed between the first stud portion 1 and the second stud portion 2, the fixing position on the natural hair H does not shift or come off easily from the natural hair H. The person who receives the hair augmentation treatment can perform the hair augmentation treatment with confidence. When there is only the first stud portion 1, it functions as "anti-slip".

[0037] Also in the method of attaching the hair material of Example 2, the photocuring adhesive (the first stud portion 1, the second stud portion 2) is not directly applied to the tubular member 5 on the natural hair H. Even after these first stud portion 1 and second stud portion 2 are cured, the modification process of the tubular member 5 becomes possible. For example, if it is before crushing and fixing the tubular member 5, its position can be corrected, and if there is damage to the tubular member 5, it can be easily replaced.

[0038] In addition, in the method of attaching the hair material of Example 2, after forming the second stud portion 2 on the natural hair H, it is also possible to pass the tubular member 5 through the natural hair H and then form the first stud portion 1 in this order.

[0039] <Modification of Example 2> Figure 9 is an enlarged front view showing a modification of the tubular member of Example 2. (a) shows a trumpet shape, (b) shows a substantially conical shape, and (c) shows a wound shape member. The modification of Example 2 is obtained by deforming the shape of the tubular member 5. The tubular member 5 is not limited to a simple cylindrical shape. As shown in Fig. 9(a), one end of the tubular member 5 may be formed to expand so as to be easily inserted into the natural hair H. It can be a so-called "trumpet shape". When the position for inserting the natural hair H is widened in this way, the natural hair H can be easily inserted.

[0040] Also, since the tubular member 5 only needs to be easily inserted into the natural hair H and not easily detached from the natural hair H when crushed later, it may be in a substantially conical shape as shown in Fig. 9(b). Furthermore, it does not necessarily have to be in a tubular shape from the beginning. For example, as shown in Fig. 9(c), a method may be used in which the cross-sectional shape has a V shape, it is attached so as to sandwich the natural hair H from the side, and then deformed so as to be crushed and fixed to the natural hair.

Example

[0041] Figure 10 is an explanatory diagram showing the working procedure of Example 3. (a) shows the state of a plurality of natural hairs before processing, (b) shows the state in which a tubular member is attached to the line hair material, (c) shows the state in which the first staple portions are respectively formed on two natural hairs, and (d) shows the state in which each tubular member is passed through the first staple portion. Figure 11 is an explanatory diagram showing the working procedure of Example 3. (e) shows the state in which each tubular member is passed through the first staple portion and the second staple portion is formed, and (f) shows the state in which the second staple portion is cured. In the illustrated example, only one natural hair is shown, but it is not limited to one and may be a plurality. The method of attaching the hair material in Example 3 is a method called the so-called "line hair increasing method". This method is a method of fixing to the natural hair H a thing in which tubular members 5 are attached to both ends of a trunk hair material MAH to which a large number of hair materials (branch hair materials BAH) are hooked, and it is a attaching method that enables a large number of hair increases in one process. Figure 12 is a flowchart showing the working procedure of Example 3. The method of attaching the hair material in Example 3 is a hair growth method in which the main hair material MAH is hooked onto the natural hair H using two tubular members 5 and fixed to a person's hair. The working procedure in Example 3 is substantially the same as that in Example 2, except for the procedure of fixing the tubular members 5 at two locations.

[0042] In the method of attaching the hair material in Example 3, first, branch hair materials BAH are attached to a plurality of locations on the main hair material MAH. Prepare a member with tubular members 5 attached to both ends of this main hair material MAH (Fig. 10(b)). The illustrated example shows an example in which five bundles of branch hair materials BAH are attached to one main hair material MAH, but the number is not limited to this.

[0043] Regarding a person's natural hair H, as in Example 1 and Example 2, the first stud portions 1 that function as "anti-slip" are respectively formed with a photocuring adhesive (Fig. 10(c)). In the illustrated example, since the tubular members 5 are attached to two locations on the main hair material MAH, the first stud portions 1 form a set of two locations. Also in Example 3, the shape of the first stud portion 1 is not limited to a spherical shape, and can be various shapes such as a drop shape and an ellipsoid (prolate spheroid) shape.

[0044] Next, when hooking the tubular member 5 of the main hair material MAH onto this natural hair H, since the first stud portions 1 are formed at two locations on the natural hair H also in the method of attaching the hair material in Example 3, it becomes difficult for the tubular member 5 to come off (Fig. 10(d)). Moreover, since the first stud portions 1 that function as "anti-slip" use a photocuring adhesive, they cure within several seconds immediately after being applied to the natural hair. The next operation can proceed efficiently.

[0045] Finally, continuously to the portion where the tubular member 5 is hooked onto the natural hair H, the second stud portion 2 is formed with a photocuring adhesive (Fig. 11(e)). The irradiation light of an LED (light-emitting diode) is applied to the first stud portion 1 and the second stud portion 2 to cure them (Fig. 11(f)). The second stud portion 2 sandwiches the tubular member 5 together with the first stud portion 1 and functions as "positioning".

[0046] Even in the method of attaching the hair material of Example 3, the tubular member 5 does not directly apply the photocurable adhesive (the first staple portion 1, the second staple portion 2) to the natural hair H. Even after these first staple portions 1 and second staple portions 2 are cured, the tubular member 5 can be corrected. For example, the position can be corrected before crushing and fixing the tubular member 5, and when the tubular member 5 is damaged, it can be easily replaced.

[0047] Note that the present invention is not limited to the above-described embodiments of the invention as long as a photocurable adhesive can be used for the member for fixing the artificial hair (hair material AH) to create a retaining effect in a short time and the position and tightening force of the tightened state of the hair material AH can be easily corrected, and various modifications can be made without departing from the gist of the present invention.

Industrial Applicability

A method for attaching hair material to a person's hair using a light-curing adhesive, the method comprising the steps of: A hair material (AH) is attached to a tubular member (5) having an inner diameter large enough for the natural hair (H) to pass through; A first tack portion (1) that functions as a "stopper" is formed with a light-curing adhesive at a position close to the scalp (S) of the natural hair (H); The tubular member (5) is passed through the first tack portion (1) and hooked onto the natural hair (H); This method of attaching hair material using a light-curing adhesive comprises clamping a tubular member (5) passed through one's own hair (H) together with a first tack portion (1), and forming a second tack portion (2) that functions as a "positioning" portion on the one's own hair (H) with a light-curing adhesive.

5. 5. A method for attaching hair material using a light-curing adhesive as described in claim 3 or 4, characterized in that the first tack portion (1) is passed through the tubular member (5), and the tubular member (5) is crushed and hooked onto the natural hair (H) so that it does not come off the first tack portion (1).

6. A method for attaching hair material to a person's hair using a light-curing adhesive, the method comprising the steps of: A hair trunk material (MAH) is connected between two tubular members (5) having an inner diameter large enough for the hair itself (H) to pass through, and a plurality of hair branches (BAH) are attached to the hair trunk material (MAH); A first tack portion (1) that functions as a "stopper" is formed with a light-curing adhesive at two locations close to the scalp (S) of the natural hair (H); The method for attaching hair material using a photocurable adhesive is characterized in that each tubular member (5) is passed through two first tack parts (1), and each tubular member (5) is crushed and hooked onto the natural hair (H) so that it does not come off each first tack part (1).

7. A method for attaching hair material to a person's hair using a light-curing adhesive, the method comprising the steps of: A hair trunk material (MAH) is connected between two tubular members (5) having an inner diameter large enough for the hair itself (H) to pass through, and a plurality of hair branches (BAH) are attached to the hair trunk material (MAH); A first tack portion (1) that functions as a "positioning" portion is formed with a light-curing adhesive at two locations close to the scalp (S) of the natural hair (H); Each tubular member (5) is passed through each of the two first stud portions (1), and each tubular member (5) is crushed and hooked onto the natural hair (H) so that it does not come off each of the first stud portions (1). This method for attaching hair material using a light-curing adhesive is characterized in that a second stud (2) that functions as a "positioning" is formed on each natural hair (H) with a light-curing adhesive so that each tubular member (5) is sandwiched together with two first stud portions (1).

8. A method for attaching hair material using a photocurable adhesive as described in claim 1, 3 or 6, characterized in that the first tack portion (1) made of the photocurable adhesive is exposed to light in the visible range of an LED (light emitting diode) to harden the adhesive faster than it would harden naturally.

9. A method for attaching hair material using a photocurable adhesive as described in claim 2, 4 or 7, characterized in that the first tack portion (1) and the second tack portion (2) made of the photocurable adhesive are irradiated with light in the visible range of an LED (light emitting diode), thereby hardening the adhesive faster than when the adhesive hardens naturally.

10. A method for attaching hair material using a photocurable adhesive as described in claim 1, 3 or 6, characterized in that the first tack portion (1) made of the photocurable adhesive is exposed to ultraviolet light from an LED (light emitting diode) to harden the adhesive faster than it would harden naturally.

11. A method for attaching hair material using a photocurable adhesive as described in claim 2, 4 or 7, characterized in that the first tack portion (1) and the second tack portion (2) made of the photocurable adhesive are irradiated with ultraviolet light from an LED (light emitting diode) to harden the adhesive faster than when it hardens naturally.
