Although by law one is not allowed to say ‘permanent’, the patients who were treated 14 years ago are still clear of unwanted hair. A patient can tell how much reduction was achieved from a course of treatments after waiting 6–12 months from their last treatment. Any hair that grows after this period is new hair that the body can develop due to numerous factors such as age, diet, hormonal changes and medical conditions such as PCOS. Patients who experience new growth later in life can get touch-up treatments.
In order to achieve 100% clearance of hair in any one area, some people may need to follow up laser treatments with electrolysis to remove any remaining finer hairs. Electrolysis is the only other proven permanent hair removal method, which involves treating one hair at a time, and is a good option for smaller areas where precision is necessary (like eyebrows or upper lip).
