How often should you wash your hair when you on vacation at the beach? Even if you don't get it wet.
If you don't get it wet than you don't have to wash it with shampoo. I would see if the sand and stuff rinses off naturally with just water and conditioner. If it doesn't than you will have to wash it. Chlorine can not be rinsed out of hair it has to be shampooed. If you get sweaty and stuff co-wash. But just remember that your hair doesn't control you and its okay to wet it and and go swimming :) enjoy your vacation x
