What it is: A round brush that expertly pairs with a blow dryer to set curls, create waves, and add noticeable luster. What it does: The ceramic barrel of this round brush heats up from the blow dryer, dramatically helping to create smooth waves or loose, medium-sized curls. The perforated barrel allows air flow, thereby decreasing overall drying time. NanoIonic™ minerals condition, reduce frizz and flyaways, add shine, and help remove odors. This lightweight tool features a soft-touch handle and promises to be gentle on the hair and scalp.
