Melanin plays a crucial role in laser hair removal primarily through its ability to absorb laser energy. During the procedure, the laser targets the pigment (melanin) in the hair follicles. When the laser light is emitted, the melanin absorbs this energy, which then converts into heat. This heat damages the hair follicle, inhibiting its ability to produce new hair.

The effectiveness of the procedure is largely dependent on the contrast between the hair color and the skin color; darker hair contains more melanin, making it more efficient at absorbing laser energy. The presence of melanin directly impacts the success of the laser treatment, as the goal is to deliver sufficient energy to destroy the follicle while minimizing damage to the surrounding skin.

In contrast, melanin does not reflect laser energy or enhance hair growth, nor does it serve to protect the hair follicle. Instead, its absorbing properties are fundamental to the mechanism of action in laser hair removal, making the correct choice clear.
