Most laser treatment will take from 4-6 treatments to be fully effective. People that only get treated once or twice are not always satisfied with the results. The hair follicle must be at a certain growth stage in order to be eradicated by the laser. Naturally, people's hair grows at different stages and at different times, which is the reason any particular area needs to be treated several times for optimum results.
