1064-nm picosecond Nd:YAG laser fractional picosecond laser FPL androgenetic alopecia male pattern hair loss hair regrowth dermoscopic analysis petechiae hair shaft AGA male pattern baldness

TLDR A new laser treatment may help regrow hair in men with pattern baldness and has minimal side effects.

A pilot study involving five male participants with mild-to-moderate Androgenetic Alopecia (AGA) investigated the potential of fractional picosecond laser (FPL) therapy for promoting hair regrowth. The patients underwent three treatments at four-week intervals, followed by a four-week post-procedure assessment. Clinical improvement was observed 1 to 4 months after treatment, with a significant increase in expert panel assessment scores (p<0.001). Patient satisfaction with hair density and thickness also improved significantly at 1 and 4 months (p=0.038 and p=0.007, respectively). Adverse effects were minimal and resolved within a week. Dermoscopic analysis showed minimal petechiae with no hair shaft damage. The study concludes that 1064-nm FPL has potential for promoting hair regrowth in male pattern hair loss, but further research is recommended.
