Laser hair removal is a non-invasive treatment that uses concentrated light beams to target and destroy hair follicles, preventing future hair growth. The procedure is effective for various areas of the body and works on most hair colors, though it is most effective on dark hair and light skin. Typically requiring multiple sessions, laser hair removal provides long-lasting results and can significantly reduce hair regrowth, making it a popular alternative to traditional hair removal methods like waxing or shaving.
