In this embodiment, after the first glue composition 31 and a second glue composition 32 are coated on the first outer surface 2102 of the first carrier 210 and the second outer surface 2202 of the second carrier 220, then a UV lamp (not shown) is used to irradiate the first glue composition 31 and a second glue composition 32 to produce a photocuring reaction to complete the hair piece 100.

It should be noted that when the weight of mineral energy powder is higher than 50% of the weight of the colloid, it will negatively affect the effect of light curing.

It is worth mentioning that when the base glue uses heat-curable glue, and the colloid of the glue composition is light-curable glue, it can avoid the heating clip (not shown) used when removing the hair piece 100 from destroying the integrity of the primer, and then it can be used repeatedly. One of the plates of the heating clamp has a heating temperature, and the other plate does not.

The steps of the hair extension method of the present invention are described below.

In this embodiment, the adhesive includes a combination of colloid and mineral energy powder. Wherein the colloid is photocurable glue, and the weight of the mineral energy powder is 10% of the colloid. In one embodiment, the weight of the adhesive mineral energy powder is 1% or 10%-20% of the colloid.

Then, the adhesive is irradiated with a UV lamp (not shown), so that the adhesive is cured by light.

In addition, when the hair piece 100 is to be removed from the hair of the human body, a heating clamp can be used to clamp the part where the hair piece 100 is bonded to the human hair. The plate with heating temperature in the heating clamp contacts the adhesive, and the heated temperature is used to make the adhesive react to remove the viscosity, so that the hair piece 100 is easily and completely separated from the hair.

In this embodiment, the primers of the hair piece 100 use heat-curable glue, and the colloid of the adhesive composition 3 and the glue of the adhesive are light-curable glue, so that the integrity of the primer can be prevented from being damaged by the heating clip used when removing the hair piece 100, and can be reused.

In addition, it is worth mentioning that there can be only one glue composition 3 in the hair piece 100, but using two glue compositions 3, in addition to increasing the amount of mineral energy powder used to improve the effect of negative ions and/or far infrared rays on the human body, can also keep one of the glue compositions 3 due to physical or chemical damage, and can also be reused for the next hair extension.

The above descriptions are illustrative only, not restrictive. Any equivalent modification or change made without departing from the spirit and scope of the present invention shall be included in the scope of the appended patent application.
