Laser treatments specifically target hair or follicles that contain which substance?

Laser treatments are designed to effectively target hair or follicles that contain melanin. Melanin is the pigment responsible for the color of hair and skin, and it absorbs the light emitted by the laser. The laser energy is converted into heat, which damages the hair follicle and inhibits future hair growth. This targeting of melanin allows for selective destruction of the hair follicle without affecting the surrounding tissues, making the treatment both efficient and safe.

Keratin, on the other hand, is a protein that makes up the structure of hair, nails, and the outer layer of skin. While keratin is essential for hair composition, it is not the primary target of laser treatments. Collagen is a structural protein found in the skin and is often associated with skin tightening and anti-aging treatments, rather than hair removal. Vitamin D is a nutrient that supports various bodily functions, including bone health, but it does not have a direct role in hair follicles and is not targeted in laser hair removal procedures.
