One of my fave hair tips is using baby powder. This magical stuff quickly absorbs any oil you may have in your hair and smells pretty too!
Sprinkle along the crown and at the roots on your oiliest days and you'll love how much body your hair has. It even works on us brunettes. Just make sure to brush it well and don't let it settle into your part.
You can buy Johnson's Baby Powder on drugstore.com for $5.69. Not bad for a miracle hair fix!
