Apparatus and method for stimulating hair growth
A device for stimulating hair growth applied to a user's scalp. The device includes a housing. A plurality of light emitting diodes coupled to the housing operable to emit non-coherent light, the non-coherent light having at least two intensity peaks. A plurality of pairs of teeth extending from the housing, wherein the plurality of light emitting diodes are disposed between each pair of teeth; and wherein each of the plurality of pairs of teeth parts the user's hair to expose the scalp.
1. A device for stimulating hair growth applied to a user's scalp, comprising:
a housing defining a major axis;
a plurality of light emitting diodes coupled to the housing operable to emit non-coherent light, the non-coherent light having at least two intensity peaks, wherein the plurality of light emitting diodes emits red, green, and blue light;
a plurality of pairs of teeth extending from the housing, wherein the plurality of light emitting diodes are disposed between each pair of teeth, each of the plurality of pairs of teeth parts the user's hair to expose the scalp, each of the plurality of light emitting diodes and at least two of the plurality teeth define a longitudinal axis substantially orthogonal to the major axis.
2. The device of claim 1 , wherein at least one of the intensity peaks has a wavelength in the range of approximately 425 nm to 500 nm and another of the intensity peaks has a wavelength in the range of 900-1200 nm.
3. The device of claim 1 , wherein the plurality of light emitting diodes emits monochromatic light and includes a phosphor material disposed on its surface, wherein the phosphor material converts the monochromatic light to white light.
4. The device of claim 1 , further comprising a heating element coupled to the housing and operable to transmit heat to the scalp.
5. The device of claim 4 , further comprising a fan disposed within the housing operable to blow heat transmitted from the heating element onto the scalp.
6. The device of claim 1 , wherein the plurality of pairs of teeth are movable.
7. The device of claim 1 , wherein the housing defines a reservoir, and wherein a photoactive cream is stored within the reservoir.
8. The device of claim 7 , wherein the device is operable to deposit the photoactive cream on the user's scalp.
9. The device of claim 1 , wherein the plurality of pairs of teeth vibrate.
10. The device of claim 1 , further comprising a control element coupled to the housing.
11. A method of stimulating hair growth on a user's scalp, comprising:
exposing the scalp using a hand-held device, the hand-held device has a plurality of pairs of vibrating teeth operable to part hair;
emitting non-coherent light having at least two intensity peaks onto the scalp;
applying a photoactive cream to the scalp; and
heating the scalp using the hand-held device.
12. The method of claim 11 , wherein the non-coherent light is blue light.
13. The method of claim 11 , wherein the non-coherent light is emitted in the ranges of approximately 425 nm to 500 nm and approximately 500 nm to 600 nm.
14. The method of claim 11 , wherein the hand-held device blows air to expose the scalp.
15. The method of claim 11 , wherein the non-coherent light is emitted from a plurality of light emitting diodes.
16. A device for stimulating hair growth applied to a user's scalp, comprising:
a housing;
a plurality of white light emitting diodes coupled the housing emitting white light including at least one intensity peak having a wavelength between approximately 900 nm and 1200 nm;
a plurality of pairs of teeth extending from the housing, wherein the plurality of white light emitting diodes are disposed between each pair of teeth, each of the plurality of pairs of teeth parts the user's hair to expose the scalp; and
a photoactive cream disposed within the housing, the photoactive cream being dispersible to the scalp.
