HOW TO USE: Wash your hair and dry it to 75 to 80 percent dryness. Depending on your hair length and desired curl size, wrap a suitable amount of hair around the roller, reverse the curler, and secure it by folding the end. For longer hair, two rollers can be used together as one. Different wrapping techniques create various wave styles; follow your preferred curl pattern or refer to standard curling tutorials. Hair stays securely on the roller without clips—fasten the strap at both ends of the roller. Wear overnight or leave in for up to 1 hour. In the morning, remove the rollers gently and style with your fingers, or use a light mist of hairspray for added hold. FEATURES: 1.
