Which wavelength is the most common for laser hair removal?

The most common wavelength for laser hair removal falls within the range of 700 to 1064 nm. This particular range is effective for targeting the melanin present in hair follicles, which absorbs light in the near-infrared spectrum. Lasers operating at these wavelengths, such as the Nd:YAG laser (which operates at 1064 nm), are especially useful for treating a variety of skin types and hair colors, making them versatile for different patients.

The choice of this specific wavelength range is significant because it allows for deeper penetration of the laser energy into the skin without damaging the upper layers. This depth is critical for reaching the hair follicles effectively, promoting a higher efficacy in hair removal while minimizing side effects. Furthermore, the longer wavelengths are safer for the surrounding tissue, which is why they have become the standard in the industry.

While the other wavelength ranges mentioned in the options can be used for different types of laser treatments, they are not as effective as the 700-1064 nm range for hair removal. For instance, wavelengths below 700 nm may not penetrate deeply enough to effectively target hair follicles, while those above 1064 nm might be less effective at being absorbed by the hair melanin. Thus, the 700-1064
