TLDR Low-Level Laser Therapy might be a good alternative for hair loss when other treatments fail, but its effectiveness varies and more research is needed.

The 2017 document discussed the potential of Low-Level Laser Therapy (LLLT) as a treatment for various forms of hair loss, including female pattern hair loss (FPHL), male pattern hair loss (MPHL), alopecia areata (AA), and chemotherapy-induced alopecia (CIA). The authors concluded that LLLT could be a promising alternative for patients who do not respond to conventional treatments or do not wish to undergo hair transplantation. However, they noted that the effectiveness of LLLT varies among individuals, and factors predicting who will benefit most from the treatment need to be identified. They also called for larger, longer-term placebo-controlled studies to confirm these findings and establish more consistent treatment protocols.
