Question of the Day: How often should I wash my Natural Hair? Answer: As often as you want to. It is really up to your lifestyle. I work out a lot, so I wash my hair at least 2 times a week. When I wash my hair, I cowash in between the week and shampoo at the end of the week. This is the best method for me and my hair. For my girls, once a week works fine and sometimes we have gone once every two weeks especially off-soccer-season. The key thing to remember is when you do wash your hair, remember to MOISTURIZE!! I also deep condition after my shampoo. How often do you wash your hair?
