Problems solved by technology

However, side effects such as burns and age spots are prone to occur along with cell destruction, so this treatment should only be performed by specialists
[0003] While it would be desirable to be able to easily perform hair removal and hair regrowth at home, there is currently no technology that meets this need
In addition, although an instrument for assisting hair growth and hair regeneration is proposed in Japanese Patent Laid-Open No. 2002-541906, which applies light vibrations to the scalp while radiating light, but in this case the light radiation only helps The hair tonic penetrates into the scalp to nourish the hair papilla, while this light radiation is not used to have an effect on hair growth and hair regrowth
Although a method of suppressing hair growth using low-power light is proposed in Japanese Patent Laid-Open No. 2005-519692, appropriate effects cannot be obtained by this technique alone

Embodiment Construction

[0034] figure 1 A conditioning light radiator 10 for use in the invention is shown. The adjusting light radiator 10 is provided with a light source in the form of a xenon flash lamp 12 , and outputs adjusting light in the form of a flash with a certain wavelength through a filter (filter) 14 , such as adjusting light with a wavelength of 400nm-600nm. Therefore, the conditioning light radiator 10 has: a capacitor 14 which accumulates charges for causing the xenon flash lamp 12 to emit light; and a charging / discharging circuit 18 which charges and discharges the capacitor 16 . The charging / discharging circuit 18 is configured to discharge the capacitor with a one-shot pulse, so that the xenon flash lamp 12 emits light for a short time (not exceeding 1 ms), and outputs a flash in the form of modulated light.

[0035] The adjustment light irradiated by the adjustment light radiator 10 needs to be absorbed by the skin, and when determining the wavelength of the absorbed light, suc...

Abstract

A controlled light having a wavelength of 400 to 600 nm inclusive and an energy of 0.01 to 1 J / cm2 inclusive is irradiated to a site around a hair root for 1 ms or shorter in the form of a flash light, thereby causing the absorption of the light by a biological light-absorptive component which occurs in the periphery of the hair root. Thus, the growth of hair can be controlled with causing little adverse side-effects.

Description

technical field [0001] The invention relates to a hair growth regulating method and a regulating device thereof which use light to regulate hair growth. Background technique [0002] Hair removal by radiation of light is well known in the medical world. This involves using a high-output (class 4) laser to destroy the cells at the root (and follicle) of the hair to necrosis the hair. However, side effects such as burns and age spots are prone to occur along with cell destruction, so this treatment should only be performed by specialists. [0003] While it would be desirable to be able to easily perform hair removal and hair regrowth at home, there is currently no technology that meets this need. In addition, although an instrument for assisting hair growth and hair regeneration is proposed in Japanese Patent Laid-Open No. 2002-541906, which applies light vibrations to the scalp while radiating light, but in this case the light radiation only helps The hair tonic penetrates...
