hmm.... Ok, have you looked into Laser yet ? You do not do it to yourself. As for when to pluck or wax afterwards, I'd say not at all. After a laser treatment it can be 3 weeks before the hairs fall out ( it varies ). Normally they recommend laser ever 6 wks or so, to give time for the dead follicles to exit and the next cycle of hair growth to get going well enough to be a target.
Especially the waxing thing, you do want to shave prior to a treatment, but don't wax, that would make it hard for the laser to be effective.
The first time you may not notice any change, there are a LOT of follicles. Some won't be killed off immediately and some are just coming up to the surface. Have your tech take some pictures before you start.
What color of hair do you have, how old are you and what is your skin tone ??
