Low-Level Light Therapy for Hair Loss: A Scientific Review
Dr. Kumar’s Take:
Low-Level Light Therapy (LLLT) has emerged as a promising, non-invasive treatment for androgenetic alopecia (AGA). This study highlights LLLT’s ability to stimulate hair follicle regeneration, increase hair density, and enhance hair growth. While it does not replace standard treatments like minoxidil or finasteride, it presents a viable alternative for those seeking non-pharmaceutical options.
Brief Summary:
The study examines the effects of LLLT on individuals with AGA, focusing on its ability to stimulate hair follicles through photobiomodulation. LLLT employs wavelengths between 650-950 nm to penetrate the scalp and activate mitochondrial processes in hair follicle stem cells. This mechanism helps shift hair follicles from the resting (telogen) phase to the growth (anagen) phase, thereby promoting hair regrowth.
