Is Laser Hair Removal Permanent?
Laser hair removal is normally accomplished in a series of monthly treatment sessions. The average number of sessions to achieve permanent hair reduction can depend on many factors. Some patients have experienced permanent hair reduction in a single treatment session, but there is limited data on how long hair reduction lasts, or how much is permanent hair reduction.
It is common in between sessions some hair will regrow. Hairs that may have been dormant during the previous treatment session may now be in the growth phase. Multiple treatment sessions ensures that all the hairs are subjected to being lasered. Many patients find that periodic maintenance sessions done once or twice a year is sufficient in keeping hair at bay after completing the initial treatment phase.
