The best laser in laser hair removal, that is, the gold standard, is the Alexandrite laser. Because the Alexandrite laser produces light at a wavelength of 755nm. This wavelength is the wavelength that affects the hair the most. There is a substance called melanin in the hair, melanin gives color to the hair. Lasers see the dark color inside the hair. That is, the laser light is held by the melanin, heating the hair root. This heat prevents the regrowth of the hairs. The Alexandrite laser gives the most energy to heat the hair root. For the best laser hair removal, enough energy should reach the hair root. Therefore, the laser epilation device must be powerful. In addition, it is necessary to prevent this energy from damaging the skin. For this, Alexandrite lasers are used with special air cooling systems. During the laser epilation process, blowing cold air prevents the skin from burning. In this way, high doses of laser energy can be delivered to the hair root. One of the reasons why we say Alexandrite laser to the question of which laser epilation is better is the advantage of shooting without touching the skin. Shooting without touching the skin is more convenient than hygiene vaccination, especially in areas such as bikinis.

Numerous studies have been conducted to answer the question of which laser hair removal device is better. There are comparative studies with other laser hair removal devices. In the studies conducted with the Diot laser, Nd yag laser and Alexandrite laser used in laser epilation, the hair reduction rates of the people treated with these lasers were compared and it was shown that the hairs decreased more in the laser epilation process performed with the Alexandrite laser. Some of these studies are:
