TLDR Low-level light/laser therapy is effective in treating male and female pattern hair loss without side effects.

A systematic review of 298 articles was conducted to assess the effectiveness of low-level light/laser therapy (LLLT) in treating male pattern hair loss (MPHL) and female pattern hair loss (FPHL). Out of these, 136 articles focused on MPHL and FPHL, and 36 of these specifically on LLLT. After excluding systematic reviews, seven randomized controlled trials (RCTs) were analyzed. The conclusion from these seven RCTs was that LLLT had a positive effect on treating MPHL and/or FPHL, with no reported side effects.
