Here are the recommendations from the Mark & M.E. and Wax It All Salons. If you have been shaving or trimming, we request a minimum of two weeks growth before you come in for a wax. If you have been getting waxed, then you can return to the salon any time after three weeks. Although it often takes 4-6 weeks for all of your hair to grow in enough to get a thorough wax, we understand that it is summer and you may need to come in more often. See you soon!    www.marknme.com
