If you have fine hair, I recommend you use volumizing products—including shampoos, sprays, and creams—that don’t contain alcohol, which will make your hair dry and lifeless. Styling products should be applied when hair is soaking wet, and it’s best to air-dry your hair until it’s mostly dry before using a blow-dryer and brush. Be sure to always use a small brush and small-size rollers when styling, and don’t over-dry: The less heat you use, the more body you will have.
