Usually four to six treatments are required, depending on the size of the treated area and the density of the hair in the area. Patients will needs to take time between sessions (4-6 weeks) to allow for the treatment to give results. During break time, the follicles stop being active, and the hair from the treated area starts to fall out. The results with Diolaze XL are entirely permanent because the treatment targets the hair follicles to stop future hair growth processes completely. After a few treatments, you will no longer have the need to shave, wax or use any other treatments for hair removal.
