I had 4 sessions of laser hair removal but am moving abroad and cannot continue. I spaced each session by 28 days. They told me (before I said I'd quit) during the treatment I could only shave (like with razor blades) but never use wax or depilatory products like cream. Now that I've interrupted, do the same rules apply since I don't have the contact with laser anymore? Will I lose what I've done? What is the max. Allowed time for the next session?
