What characteristic of hair makes it suitable for laser hair removal?

The suitability of hair for laser hair removal primarily hinges on its color and coarseness. Laser hair removal works by targeting the pigment (melanin) in the hair shaft. Darker, coarser hair possesses a higher concentration of melanin, making it more readily absorb the laser energy. This absorption leads to effective destruction of the hair follicle, preventing future growth.

Furthermore, the coarseness of the hair indicates a thicker shaft, which enhances the laser’s ability to penetrate and effectively treat the hair follicle. Conversely, lighter or finer hair may be less effective to treat because they contain less melanin, leading to reduced absorption of the laser energy and therefore less effective results. This characteristic of hair is what fundamentally outlines the effectiveness of laser hair removal treatments.
