Laser hair removal services have grown in popularity over the last several years, and they are increasingly becoming the go-to standard for hair removal. LASER is an acronym for light amplification by the stimulated emission of radiation. To understand how to safely perform laser, professionals must first understand how laser works. Laser treatments offer permanent hair reduction and, due to updated equipment and technology, this treatment is now available to nearly anyone. 

Laser works by utilizing pulses of light to target the pigment in hair follicles. The light energy is absorbed by areas of high pigment, melanin. Once the light energy makes contact with the hair follicle, it transfers the energy to heat energy. Over time and several treatments, this damages the follicle which then reduces and even prevents hair growth.
