How Many Laser Hair Removal Sessions?
Most people need 6–10 laser hair removal sessions, spaced 5–7 weeks apart. Each treatment eliminates roughly 10–15% of the hair, because the laser only affects follicles in their active growth phase — so repeated passes over time are required to catch each follicle while it is treatable.
Why more than one session
At any moment only a portion of your follicles are actively growing; the rest are dormant and unaffected — which is why each treatment eliminates only about 10–15% of the hair. Spacing sessions 5–7 weeks apart lets dormant follicles re-enter growth so each can be treated. Coarser, denser, or hormonally driven hair may need additional sessions.
