Abstract

A hand-held device for hair growth stimulation. The device parts the user's hair while the light source radiates user's exposed scalp. Non-light emitting teeth are uses to part the user's hair in front of an associated light source. An optional timer can be used to control the length of time the light source is activated. Parallel rows of teeth are aligned with a central row of light beams and part the individual's hair to form furrows in the user's hair as the device is combed through the user's hair. The furrows create an unobstructed path for the light beam to reach the user's scalp. Various embodiments use laser and/or non-coherent light sources to provide light energy to the user's scalp. An optional removable teeth assembly can be used to allow repair or sharing of the device.

Claims3

Dependent claims

A handheld hair treatment device, comprising:

a housing defining a major axis;
a plurality of discrete light sources secured in or to the housing, each of the discrete light sources generating a unobstructed discrete light beam;
and
a plurality of non-light emitting teeth extending from the housing, each of the non-light emitting teeth being associated with one of the discrete light beams from the discrete light sources, each of the non-light emitting teeth and its associated discrete light beam are aligned with one another and offset from one another such that each discrete light source is disposed between at least two of the plurality of non-light emitting teeth, each discrete light source and the at least two plurality of non-light emitting teeth defining a longitudinal axis orthogonal to the major axis;
whereby a user's scalp is exposed to at least one of the discrete light beams during application of light to the user's scalp.
