For 24-48hrs after you've been waxed avoid the following....
Sun exposure, deodorant, really hot showers/baths, chlorinated pools, sunbeds /self tan, spas and saunas, sports or vigorous exercise and sex as this will irritate the skin.
Exfoliate the skin up to 3 times a week with either a body scrub or a dry body brush to avoid ingrown hairs. Always moisturise afterwards.
SERIOUS STUFF
If you're having Intimate waxing, you'll need to get naked from the waist down to get a perfect wax. After all you wouldn't wear a hat to get your haircut would you!
It really is worth the time and effort and money to get it done by an expert. We are talking about the most sensitive and valued part of your body. So don't go to an amateur or you might find its not only corners that are cut!!
