Thinning hair

I’ve had 2 treatments w/alexandrite on bk, sh, up arms.

Its been 6 wks post 2nd treatment. The hairs growing now are much thinner, less coarse, and a little lighter color.

Question is: Are these hairs just now popping up the ones that were not in growing phase(dormant) when lasered or are they same hairs that are tough to kill and are just getting thinner and slowly killed off. Tough to know-any experience out there?

Also noticed lots of white hairs. Could laser take pigment out or were these white hairs blended in before start of treatments and I am now just noticing them. I’m 34yr old so may be just the start of old man syndrome <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />

My guess is that they are the hairs that weren’t in the active growing phase. However, some of them might be hairs that weren’t quite killed during the treatment.
