Tip #4. Try not to wash your hair every day. I know, sounds pretty crazy, especially to those of you with more oily hair. It's true you might be scared of turning into a grease ball, but the truth is, you're over washing your hair. Try spreading it out to every other day, your hair will adjust and adapt. It will stop producing so much sebum. If you find it hard to spread out your washings, use a little bit of baby powder. It will absorb the oils and brush right out of her hair.
