Androgenetic alopecia (AGA) is the commonest type of alopecia affecting over half of men and women. Only two drugs have been approved so far (minoxidil and finasteride), and hair transplant is the other treatment alternative. Low-level laser therapy (LLLT) has been claimed to be a new safe devise-based modality for stimulating hair growth in men and women in AGA. Searches of PubMed and Google Scholar were carried out using keywords alopecia, hair loss, and LLLT. Fifteen studies were found to be strongly relevant and were analyzed. Studies have shown that LLLT stimulated hair growth in both men and women. Studies with largest randomized controlled trials demonstrated statistically significant hair regrowth by terminal hair count in both males and females. One study also showed that LLLT and minoxidil had similar efficacy in hair growth and that combination therapy was even more effective. LLLT represents a non-invasive, safe, and potentially effective treatment option for patients with AGA who do not respond or are not tolerant to standard treatment of AGA. Moreover, combining LLLT with topical minoxidil solution and oral finasteride may act synergistic to enhance hair regrowth. However, the level of evidence of the studies is still low and hence more controlled large studies are needed.
