One waxing technique that seems like a red flag, but isn't:
Double dipping in the wax. While Nacion personally thinks it's a bit icky, she says that technically the wax is hot enough to kill any germs. Unless someone had open sores (in which case the waxer hopefully wouldn't wax them anyway), there's no way you could catch their germs from the pot of wax.
Ever wonder what's going through your waxer's mind while you're spread eagle on their table? You could ask, but that whole hot-wax-in-your-private-areas thing can be a little preoccupying, you know? That's why we tracked down these waxing salon owners: Jodi Shays of Queen Bee Waxing in Culver City, Calif., Cindy Barshop of Completely Bare Salons in New York City, and Leah Nacion of The Waxing Co. in Honolulu. They gave us the uncensored scoop on everything you'd ever want to know (and then some) about what goes on behind-the-scenes in waxing salons.
