Which laser types are commonly used for hair removal?

The combination of alexandrite, diode, and Nd:YAG lasers represents a selection of the most effective and commonly used laser types for hair removal. These lasers operate at specific wavelengths that are particularly effective in targeting the melanin in hair follicles, leading to efficient hair reduction.

Alexandrite lasers work at a wavelength of about 755 nm, which is optimal for lighter skin tones and can treat larger areas quickly. The diode laser operates at a wavelength of approximately 800-810 nm, making it versatile enough to be effective on a range of skin types, particularly medium to darker skin. Nd:YAG lasers, with a wavelength of 1064 nm, are particularly effective for darker skin types because of their deeper penetration and lower melanin absorption, reducing the risk of skin damage.

In contrast, while ruby, carbon dioxide, and other lasers may have applications in various aesthetic procedures, they are not the primary choices for hair removal purposes within the industry due to factors such as their effectiveness and safety profiles compared to the options selected. Therefore, the trio of alexandrite, diode, and Nd:YAG lasers is recognized for their established efficacy and safety in the context of hair removal.
