Add the look of volume and lift to medium and long hair with these fast-heating tourmaline ceramic rollers. Tourmaline ceramic technology at the core of each roller emits natural ions. Flocked with velvet, each hot roller grabs hair and holds it in place using the unique curler clip. How do I use it: Rollers will heat up in about 85 seconds; the ready light will indicate a temperature between 140F to 230F degrees. Using a roller, roll 1" of hair until you reach your scalp and secure with a clip. Repeat this step until all hair is rolled and secured. Leave rollers in your hair for 20 minutes for bouncy and voluminous looking curls, or 10 minutes for looser waves. Clean the unit and the heating strips with a cloth when cool. From Conair.
