Examining the Safety and Efficacy of Low-Level Laser Therapy for Male and Female Pattern Hair Loss: A Review of the Literature

This document is a review of 10 controlled clinical trials that evaluated the safety and efficacy of low-level laser therapy (LLLT) for male and female pattern hair loss. The studies used different devices, laser parameters, and regimens, but all found significant increases in terminal hair counts, hair growth, and hair coverage in treatment groups. The studies suggest that LLLT devices are a safe and effective form of treatment for androgenetic alopecia (AGA), with most subjects reporting only mild side effects that resolved within 2 weeks. However, the authors note that more research is needed to fully understand the mechanisms behind LLLT and to optimize treatment protocols.
