Which type of hair is most effectively treated with laser hair removal?

Laser hair removal is most effectively performed on dark, coarse hair due to the contrast between the hair and the skin. The laser targets the pigment (melanin) in the hair, delivering energy that is absorbed by the dark pigment. This absorption of energy leads to the hair follicle being destroyed or damaged, which inhibits future hair growth.

Dark and coarse hair has a higher melanin concentration, making it an ideal target for the laser. The coarse texture also helps in effectively absorbing the laser energy, leading to better results. In contrast, light, fine hair tends to have less pigment and may not absorb the laser energy as effectively, resulting in less effective treatment outcomes. Gray hair typically lacks pigmentation altogether and is usually resistant to laser treatment, while red hair can have mixed pigmentation that also reduces the effectiveness of the laser. Therefore, dark, coarse hair is the optimal candidate for successful laser hair removal treatments.
