I had IPL done on my abdomen and three weeks has past but not all the dark hairs have fallen out. I thought that I read somewhere that all the hairs should fall out by 3 weeks but that some of those will be ineffective as further growth may be underneath them, depending upon the hair phase.
I called the provider and they said only some will fall out depending upon the hair growth stage. Which is it, should all fall out or only some?
