Hey . to answer your questions, after the first session you will be hair free anywhere fro 4-8 weeks (in my case it was 8), you can have the second session as soon as the hairs come out ( ofcourse most of them, so you won't end up paying for a session with only a few hairs out, i have noticed if you let all the hair grow from the start right b4 ur first session , then most likely it will grow together depending on the phase of the hair)
not all hair will grow back, some of it will be gone from the first session, also the hair will be much finer. don't hesitate to ask anymore question :lol:
