What should clients avoid after receiving a spray tan to ensure it lasts?

Clients should avoid showering for at least 24 hours after receiving a spray tan to ensure the best results. This is because the active tanning ingredients, such as DHA (dihydroxyacetone), need time to develop on the skin. Showering too soon can wash away the bronzer and prevent the tanning agents from fully taking effect, leading to an uneven or lighter tan. By waiting the full 24 hours, clients allow the product to properly absorb and develop into a beautiful, natural-looking tan.

The other options, while they might also have some impact on the longevity of the tan, are less critical than the timing of the first shower after the application. Avoiding these actions can help maintain the quality of the tan, but the immediate concern should always be allowing adequate time for the spray tan to set.
