Light energy of a specific wavelength is absorbed by hair follicle melanin, and transformed into heat energy to destroy the hair papilla and hair follicle stem cells. After multiple courses of treatment, the hair becomes significantly thinner and less, and almost no longer grows rough and hard (clinically called "permanent hair reduction").
