This document discusses the role of low level laser therapy (LLLT) in the medical management of androgenetic alopecia. It provides an overview of androgenetic alopecia and the mechanisms by which LLLT may stimulate hair follicles. It then describes the author's LLLT dosing protocol and experience treating patients, showing before and after photos demonstrating hair growth with LLLT. The document concludes by referencing supporting literature on LLLT for hair loss.
