Question: 1 / 400

How does hair thickness influence the results of laser hair removal?

Thicker hair is less responsive to treatment

Only fine hair can be successfully treated

Thicker hair is generally easier to target

Thicker hair is generally easier to target in laser hair removal because the laser's energy is attracted to the pigment (melanin) in the hair shaft. A thicker hair follicle often contains more melanin, which means that the laser can effectively absorb the light energy and deliver it to the follicle. This improves the effectiveness of the treatment, as the heat generated can damage the hair follicle more efficiently, leading to better hair reduction results.

In contrast, finer hair typically has less melanin, which can make it harder for the laser to detect and effectively treat. Therefore, while laser hair removal can work on various hair types, thicker hair follicles offer a more straightforward target for the laser's energy, enhancing treatment outcomes.
