Basically just sprinkle a little baby powder on your hair (mostly it will look oily around the scalp or top) then blend it in well. I really like to brush mine since I have darker hair. It saves you time and money. It is much cheaper to use than to pay $5+ for the same thing in a much smaller bottle.
Sometimes you might get invited to a last minute event and not have time to wash your hair. You can also keep a small bottle in your purse if you are on the go.
