How often should I shampoo my hair?

That depends on the length of your hair and how often you style it. If you style your hair only occasionally, I would recommend that you wash it about once every five days. For frequent styling, I would recommend washing your hair more often than that, but not more than about twice a week.

Okay, why shouldn't I do it too often?
user
Washing your hair too often causes your hair to become dry and brittle.  Shampooing causes your hair to lose the natural oils and moisture your hair needs.  If you wash your hair too often, you are essentially depleting your hair of the natural resources it needs to stay healthy and beautiful.

Okay, any other advice?
