Hair growth laser comb

Intended purpose

An electronic, portable, head-worn or hand-operated device intended to be operated by a layperson affected by scalp hair loss (i.e., receding hairline/baldness due to androgenic alopecia) to stimulate hair growth on the scalp through the application of scheduled low-level laser therapy (LLLT). The device uses individual laser diodes to direct laser light at the scalp. It is normally available [non-prescription] over-the-counter (OTC) for use in the home.
