How permanent is IPL/LASER hair removal?

Once the light destroys an active hair follicle, that follicle will never produce another hair. However, no practitioner can completely guarantee that after an individual completes his or her series of treatments hair won’t grow back on the treated area. This is because hair follicles can stay in the dormant phase for an extended period of time. Most clients experience a seventy-five to ninety percent reduction in hair. Hair that grows back is much finer and sparser in quantity. Sometimes hormonal fluctuations may activate dormant follicles. If this happens, individual hairs or isolated patches of hair may appear on the treated areas, and touch-up treatments may be required. Once the light cauterizes these new active follicles, they will stop producing hairs.
