How often should I wash my hair?

There isn't a ""right"" answer to this question.

Your physical activities, your use of styling products and your hair type will usually determine how often you wash your hair. 

If washing everyday makes your hair too dry, try every other day or every third day.  Or, you may have very oily hair that needs washing more than once a day. 

If you condition when you shampoo, it could be that you need to shampoo daily but need to adjust the level of conditioning.
