Low-Level Laser Therapy for Hair explained

LLLT, also called photobiomodulation, uses red light at low power that does not heat or damage tissue. Clinics use helmet or hood-style devices, and home devices such as caps and combs are also sold. It is a supportive treatment, not a cure.

How Low-Level Laser Therapy for Hair works

Red light, usually around 630–680 nm, is absorbed by cells in the hair follicle and is thought to improve cell energy and blood flow. This may help follicles stay in the growth phase longer. Studies show modest benefit for male and female pattern hair loss, and it works best alongside medicine.
