In terms of pulse delivery, what is required for the hair follicle relative to the skin?

For effective hair removal using laser treatment, it is essential that the pulse duration is shorter for the hair follicle compared to the surrounding skin. This is because the hair follicle is typically deeper within the skin layers and has a larger target area for the laser energy.

A shorter pulse duration allows for a more precise application of energy, which maximizes the absorption by the melanin in the hair follicle while minimizing the potential for damage to the surrounding skin. By delivering energy rapidly, the treatment can effectively heat and destroy the follicle without overheating the skin's surface.

Thus, the relationship between pulse delivery times for hair follicles and skin is crucial in laser hair removal practices, making a shorter pulse duration for the hair follicle an essential aspect of effective treatment protocols.
