Is it true that laser hair removal can cause more hair growth than what I started with?

This occurrence HAS been reported by consumers on various forums, although it has not been medically proven or confirmed. It is a rare occurrence and usually seems to happen when treating woman’s face or men’s back/shoulders/upper arms – usually when treating SPARSE SINGLE HAIRS or FINE VELLUS hairs and at lower settings. The best way to stay on the safe side is to only treat areas with laser that have coarse dark hair and make sure the technician doesn’t touch any sparse or vellus hairs. Those hairs should be removed with electrolysis.
