The Hot Tools Professional One-Step Blowout Attachment brush head is designed with all of the same features you love to help you craft the best at-home professional blowouts. More versatility, more close-to-the-root volume, more shine. Equally great for shorter styles as it is for styling variety - hello loose curls. The unique barrel shape creates lift at the root (and lets you get even closer), crafts curled ends and consistently gorgeous results. The shape isn't the only thing that makes this barrel unique. Combined BoarTech2 bristles with Refresh Activated charcoal help brighten hair - great for 2nd day hair.
