Laser hair removal is a medical procedure that uses concentrated light beams (laser) to target and destroy hair follicles, reducing hair growth. The laser emits a specific wavelength of light that is absorbed by the pigment (melanin) in the hair. This process damages the hair follicle, inhibiting future hair growth. It is commonly used for long-term hair reduction on areas like the face, legs, underarms, and bikini line. The treatment is usually performed by a trained specialist and may require multiple sessions for optimal results.
