Waxing for hair removal cannot be preformed on clients who are taking Accutane, Retin-A, or antibiotics, as this may cause skin sensitivity. The hair length must be at least 1/4 inches or 3-4 weeks worth of growth. We also recommend that you wait 24 hrs after waxing before sunbathing, tanning, or swimming. It is best to wax 3-5 days before a special occasion or vacation.
