Laser hair removal is an effective solution to treating unwanted hair. The HighSpeed LightSheer DUET uses state-of-the-art diode lasers with vacuum-assist technology to remove unwanted hair and with greater speed and comfort than other methods. The HighSpeed LightSheer DUET is a laser that produces a larger beam of highly concentrated light. During the procedure, the laser pulses for a fraction of a second, allowing the hair to absorb the light and heat up. As it heats up, the hair shaft and bulb are damaged which significantly impedes its ability to re-grow. Laser hair removal requires multiple treatments. This is because the laser works best when hairs are in an early growth stage (referred to as anagen), and all the hairs are not in this phase at the same time.
