photobiomodulation therapy continuous wave red laser 660 nm alopecia areata hair regrowth PBMT red laser AA

TLDR Red laser therapy helped regrow hair in an alopecia areata patient within 21 days.

Photobiomodulation therapy (PBMT) using a continuous wave red laser (660 nm) was applied as monotherapy to a patient with alopecia areata (AA), resulting in significant hair regrowth within 7 days and complete resolution of the patient's aesthetic concern by the 21st day. This case suggests that PBMT could be a promising treatment for AA, though further studies are needed to confirm its efficacy.
