Laser hair removal works by using concentrated light that targets melanin (pigment) in the hair, converting it to heat to damage the hair follicle, which inhibits or delays future hair growth.

  This makes an effective way to achieve long-term hair reduction by destroying the follicle's ability to grow hair. 

Since hair grows in cycles (growth, rest, shedding), multiple sessions are needed to catch hairs in the active growth (anagen) phase for best results, leading to smoother skin and fewer ingrown hairs.
