We recommend waiting at least 4-8 hours following your spray tan before taking your first shower, but no more than 24 hours. When we suggest wait at least four hours after your spray tan to shower, we also mean avoid any moisture. So if you plan to swim or go for a run then it's best to wait until later in the day. Using a dry shampoo is one way to keep your hair looking fresh even after a spray tan. Your hair will still get wet when you take showers, just not as wet as if you had dyed it red! There are lots of brands out there that sell dry shampoos and some people say they work better for blondes than brunettes. The only thing to watch out for is if the product contains alcohol, because this will dissolve your spray tan. People sometimes ask us if they can use their spray tan on their face. The truth is that products designed for skin actually work better for hair since hairs grow on the skin's surface. However, if you do want to use a facial spray tan then be sure to ask first if it contains any alcohol or other ingredients that could strip your skin of its natural glow.
