Understanding the Science Behind Laser Hair Removal How Laser Hair Removal Works Laser hair removal uses a principle called selective photothermolysis . A focused laser beam targets melanin , the pigment in hair, and converts light into heat. That heat damages the hair follicle , reducing its ability to produce new hair over time. Because only active follicles absorb the laser energy, the process must be repeated several times to reach all hair growth phases. For best results, ensure your provider matches the laser wavelength to your skin and hair type. The correct wavelength prevents burns and boosts effectiveness. What Happens Inside the Hair Follicle Not every follicle reacts the same way. If a follicle is completely destroyed , hair will never regrow from it. However, if it’s merely damaged , it may recover after several months, producing finer, lighter hairs. That’s why results differ so much among individuals—even when they undergo the same number of sessions. Why Multiple Sessions Are Required Hair grows in cycles: Anagen (growth) – the active phase targeted by lasers Catagen (transition) – a short resting phase Telogen (shedding) – old hair falls out before new growth Because only follicles in the anagen pha
