Are the results permanent?

This method can achieve a permanent effect. Generally, 5to 8 treatment sessions on one specific area are required for long-lasting results. That's because hair grows in cycles comprised of 3 phases. It's virtually impossible to destroy all the hair during the appropriate stage of the hair growth cycle in one single treatment session. Still, most hair that is destroyed in the growth phase has been reported to stay at bay for as long as one year. Further, hair that may come back is usually finer and lighter, creating a very "normal" and pleasing appearance.
