HOW TO USE Wash your hair and get it to 75 to 80 percent dry. Depending on the length of your hair and the curl size you want, wrap an appropriate amount of hair around the roller, reverse the curler, and secure it by folding the leftover end. (For longer hair, two rollers can be used together as one.) Different techniques create different wave styles. Follow the curl type you desire or refer to other curling tutorials. Hair stays securely on the roller without clips. Fasten the strap at both ends of the roller, then go to sleep or wait up to 1 hour. Wake up with natural curls the next day. Remove the rollers carefully and style your hair with your fingers, or use a light mist of hairspray to help set the curls. FEATURES 1.
