The quick response is 7 to 10 days. Designs look fresh for about a week and fade slowly over time. Remnants of the design can sometimes last 3-4 weeks especially on thick areas such as palms and feet. To prolong the life of your design, apply beeswax balm or olive oil before bathing or swimming, and stay out of chlorinated pools. If you sunbathe, henna will act as a sun block and a reverse image will be left when the henna fades. Traditionally, new brides are exempt from doing housework while they have a trace of the henna design left on their skin!
