Generally, a little goes a long way. Start with a small amount, one pump, and slowly increase the amount until you see the results you want. Since it depends on the length and thickness of your hair, the perfect amount is something you will discover for yourself. Your hair should never feel greasy or oily once it is dry. If it does, you’ve used too much. Always remember it is absolutely essential that Frizz Ease® Original 6 Effects Serum should be applied to soaking-wet hair. Do not towel dry before application.
