When must I schedule my wax appointment if I’m planning a spray tan? Always book the wax a full day before having a spray tan. The wax leaves a residue on the surface, blocking the tan product from entering the skin. This will leave a white ring around your underarms, top lip or brows or bikini area! Ask your beautician to wipe down this area with alcohol to reduce the waxy film and by the following day you’re good to go. Book your EXPRESS tan for R330, this takes 2-4 hours to develop instead of 8. Urban Lash & Tan is available on 0763864793.
