  As shown in FIG. 1, the hair-growth apparatus is roughly composed of a light irradiation unit 1 that irradiates the skin with light H, and a control unit 2 that controls driving of the light irradiation unit 1.

  The light irradiation unit 1 includes a light source unit 3 that emits light H for growing hair, a light guide unit 4 that is a light guide unit that guides the light H emitted from the light source unit 3 to the skin, It comprises a condensing lens 5 which is a condensing means provided between the light guide unit 4.

  The light source unit 3 is accommodated in the housing 6. For the light source unit 3, for example, a light emitting diode that emits light having a specific absorption wavelength of water is used. The specific absorption wavelength of water is a wavelength that shows a strong absorbance compared to other wavelengths when light is absorbed by water, or shows a sharp change in absorbance. This is due to the group. Particularly in the near-infrared region, it is known that the specific absorption wavelength of water is around 950 nm, around 1150 nm, around 1450 nm, and around 1790 nm. Among these, a wavelength of 950 nm or 1450 nm is desirable. If it is the light of this wavelength, the effect of growing hair can be enhanced without causing skin irritation.

  In addition, a short wavelength laser is used in place of the light emitting diode, or a filter for wavelength selection is provided between the light source unit 3 and the irradiation site (skin) for a halogen lamp or a broadband laser to use only a necessary wavelength. It is good also as a form.

  The light guide 4 is attached to one end of the housing 1. The light guide 4 is made of a metal such as gold, silver, or aluminum, and is formed in a cylindrical shape having a diameter of about 1 mm. The light guide unit 4 is provided with one end in the longitudinal direction on the light source unit 3 side and the other end in contact with the skin. The light guide unit 4 serves to guide the light H emitted from the light source unit 3 to the skin.

  The condenser lens 5 is disposed between the light source unit 3 and the light guide unit 4 and is provided in contact with one end of the light guide unit 4. The light H emitted from the light source unit 3 is collected by the condenser lens 5 arranged in front of the light source unit 3 and then sent to the light guide unit 4 provided in contact with the condenser lens 5. By providing the condensing lens 5, the light H emitted from the light source unit 3 can be sent to the light guide unit 4 without leakage.

  A pressure sensor 7 and an attachment 8 are provided at a portion of the light guide 4 that contacts the skin. The pressure sensor 7 detects a contact pressure when the tip of the light guide unit 4 contacts the skin. The attachment 8 directly contacts the skin and functions to protect the skin from being damaged. Note that the pressure sensor 7 only needs to be able to confirm contact with the skin. For example, a moisture amount detection sensor or a temperature sensor may be replaced with the pressure sensor 7.

  The control unit 2 includes a power supply unit 9 that emits light from the light source unit 3, a pulse control unit 10, a timer 11, and an on / off switch 12. The power supply unit 9, the pulse control unit 10 and the timer 11 are all housed in the same control box 13. The on / off switch 12 is provided independently of the control box 13.

For example, the light H having a wavelength of 950 nm is irradiated to a person under 50 years old, and 1450 nm is irradiated to persons of all ages, so that the hair growth effect is further improved. This is because the light H having a wavelength of 1450 nm absorbs water more strongly than the light H having a wavelength of 950 nm, so that an elderly person with less water can exhibit a hair-growth effect by using the light H having a wavelength of 1450 nm. It is considered a thing.

  The light H is pulsed by the pulse controller 10. Further, the light H is irradiated by the timer 11 for 15 minutes or more.
