More options, more results. Introducing the Hot Tools Professional Black Gold 2.4” One-Step Blowout Attachment Brush Head. The small size replacement 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. Part of the Black Gold collection, this unique tool features a styling surface that was designed by experts to be the ultimate in styling tools. Thermaglide ceramic coating distributes heat evenly to help reduce overstyling damage, and keep hair looking smooth and shiny. The One-Step Blowout Attachment Brush Head easily fits with the One-Step Blowout Dryer Interchangeable Handle. How-to-use: 1) First make sure your One-Step Blowout unit is off, unplugged and fully cool. 2) Align your new attachment piece with the handle top and insert with a slight twist to the left until you hear a click. 3) Enjoy gorgeous blowouts.
