The procedure works on the principle of selective photothermolysis: a laser wavelength is selected to be preferentially absorbed by melanin in the hair shaft and follicle bulb, converting light energy to heat that damages the follicular papilla and matrix cells responsible for hair production. Results are traditionally strongest on clients with darker hair and lighter skin, though modern multi-wavelength platforms have extended candidacy to a broader skin…

Hair grows in three distinct phases — anagen (active growth), catagen (transition), and telogen (resting) — and laser energy is only effective during the anagen phase when the follicle is actively producing hair and connected to the papilla. This is why multiple sessions spaced four to eight weeks apart are necessary: each session captures a different cohort of follicles in their active growth phase. Most clients require six to eight sessions for the…
