Which method of hair removal uses light to destroy hair follicles?

The method of hair removal that utilizes light to destroy hair follicles is laser hair removal. This technique involves directing concentrated beams of light (lasers) onto the skin, where the pigment in the hair absorbs the light energy. This absorption of light generates heat, which effectively damages the hair follicle and inhibits future hair growth.

Laser hair removal is particularly effective for individuals with a contrasting relationship between their skin tone and hair color, enabling the laser to target the pigments in the hair while minimizing impact on surrounding skin. It allows for a quicker and more efficient process than many traditional hair removal methods, leading to longer-lasting results.

In comparison, electrolysis involves using an electric current to destroy the hair follicle individually, while waxing and threading are physical methods that remove hair from the surface of the skin without affecting the follicle itself.
