If you choose to get waxed by a pro, make sure they're a REPUTABLE pro.
I went to get my legs and arms waxed once at a local beautician... and I have scars to prove it
(wax was a bit too hot I think, also she didn't always pull the strip off properly) She's qualified and all, just not all that good. Never going there again!
So... go to a reputable waxer. Preferably a salon, you'd probably get better quality there (not to mention they normally have private rooms in which you'd feel more comfortable).
