Laser hair removal primarily works by targeting the pigment in hair follicles using concentrated light. This light energy is absorbed by the melanin in the hair, which then heats up and damages the follicle. As a result, this method can significantly reduce hair growth over time by impairing the follicles' ability to produce new hair.

While some hair may be permanently removed, laser hair removal does not guarantee complete or permanent hair removal for all individuals. The treatment is most effective during the anagen (growth) phase of the hair cycle, and because hair grows in cycles, multiple sessions are required to target hair at different stages. Consequently, while the process can lead to a long-lasting reduction in hair density and thickness, it typically does not result in immediate total hair loss or have no effect at all on future hair growth. Over time, some individuals may experience regrowth, but it is generally finer and lighter than before.

This nuanced understanding of how laser hair removal affects hair growth underscores the effectiveness of the treatment over time, making it a suitable option for those seeking to reduce unwanted hair.
