What is a potential effect of increased melanin in hair during laser hair removal?

The presence of increased melanin in hair can enhance the effectiveness of laser hair removal treatments. This is because laser hair removal systems are designed to target the melanin in the hair follicles. When there is more melanin present, the absorption of the laser's energy is more efficient, which allows for better destruction of the hair follicle.

This increased efficacy can lead to more successful hair removal outcomes for individuals with darker hair since the contrast between the hair color and the skin tone allows the laser to focus on the melanin-rich hair more effectively. In contrast, individuals with lighter hair may present challenges for laser hair removal due to their lower melanin content, which can result in lower efficacy of the treatment.
