Is laser hair removal really permanent or 100% permanent?
Hairs has three distinct growth phase that is Active growth phase, Regressive phase and Resting phase. The laser most effectively disables hair that is in the active growth. Our hairs are always in a different hair growth cycle, even after several times of laser hair removal treatment, laser only can disables hair that is in the active growth not disables hairs that is in other growth phase. That is the reason of laser hair removal can not really removal hairs forever.
