- Abstract
BACKGROUND: There are limitations and side effects of currently approved treatments for AGA, such as topical minoxidil, oral finasteride, and low-level light therapy. OBJECTIVE: This study aimed to investigate the potential of fractional picosecond laser (FPL) therapy for promoting hair regrowth. METHODS: This was a pilot study in which five male participants were treated with a 1064-nm FPL for mild-to-moderate AGA. The patients underwent three treatments at four-week intervals, followed by a four-week post-procedure assessment. Expert panel assessment score and patient satisfaction was assessed using a seven-point scale. Dermoscopic analysis was conducted to evaluate hair shafts. Adverse effects were also monitored. RESULTS: Clinical improvement was observed at 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. CONCLUSION: The preliminary study demonstrates the potential of 1064-nm FPL for promoting hair regrowth in male pattern hair loss. Nonetheless, further research is recommended to elucidate and ratify for the optimization of this promising treatment approach.
