It's Giving Body Medium Hot Thermal Round Brush

Directions: 

-Start with fully-dried hair and add heat protectant. 

-Tap the power button to turn your tool on. You’ll hear a double beep (in about 40-50 seconds) when it’s fully warmed and ready for styling. Once you’re done, tap the power button again to turn your brush off. 

-For major root volume, over direct small horizontal sections (a.k.a. position hair opposite of its natural falling direction) and place the hot brush underneath the hair, by the root. Hold for a few seconds before continuing down the lengths. 

-For perfectly styled curtain bangs, use the hot brush to grab each bang section at the root, then diagonally roll it away from the face.

-For loose waves, use the hot brush to grab hair at the root and twist away from the face so that the section is wrapped around the barrel once. Slowly twist as you pull the brush down vertically.
