Цели: This study aimed to investigate the potential of fractional picosecond laser (FPL) therapy for promoting hair regrowth. Введение: There are limitations and side effects of current FDA-approved treatments for AGA, such as topical minoxidil, oral finasteride, and low-level light therapy. Материалы / методы: This was a pilot study in 5 male participants treated with a 1064-nm FPL for mild-to-moderate AGA. The patients underwent three treatments at 4-week intervals, followed by a 4-week post-procedure assessment. Expert panel assessment score and patient satisfaction were assessed using a 7-point scale. Dermoscopic analysis was conducted to evaluate hair shafts. Adverse effects were also monitored. Результаты: 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. Заключение: 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.
