Red light therapy stimulates hair follicles at the cellular level, promoting growth and reversing the miniaturization process seen in androgenetic alopecia (pattern hair loss).
A 2021 study published in Annals of Dermatology found that 650 nm red light treatment significantly extended hair follicle growth phases and identified key transcriptional mechanisms behind its regrowth effects.
This research confirms red light therapy as a safe, non-invasive alternative for both men and women experiencing hair loss.
