Does laser hair growth therapy actually work?

Multiple FDA-cleared clinical trials demonstrate that LLLT can increase hair count by 20-40% after 6 months. However, results vary significantly by individual, and it works best for androgenetic alopecia (pattern hair loss) in early-to-moderate stages.

Are there side effects from LLLT hair devices?

Side effects are minimal and rare. Some users report mild scalp warmth or tingling during sessions. No serious adverse effects have been reported in clinical trials. LLLT does not cause hair loss, skin damage, or systemic effects.
