Alexandrite lasers are particularly effective for hair removal in individuals with light to medium skin types, thanks to their ability to emit a wavelength that is well absorbed by the melanin in hair follicles. This makes it particularly efficient and minimizes damage to surrounding skin.

Nd:YAG lasers, on the other hand, are versatile and can be safely used on darker skin types. They penetrate deeper into the skin, allowing for effective hair removal across a wider range of skin tones. The combination of both Alexandrite and Nd:YAG lasers provides practitioners with the ability to tailor hair removal treatments to the individual needs of clients based on skin type and hair characteristics, making them a preferred choice in the industry.

The other options do not represent the most common lasers used for hair removal. Coherent lasers are not a specific type known for hair removal and generally refer to a concept in laser technology rather than a specific device. Diode lasers are indeed commonly used as well, but the combination of Alexandrite and Nd:YAG lasers is highlighted here as particularly effective across more diverse client needs.
