This is the heated styling brush that creates salon-quality results for fine or shorter hair at home. It heats up quickly to 395° in just 30 seconds and creates curls in delicate or shoulder-length hair that last 24 hours, even in humidity. The brush’s 1"-diameter tourmaline ceramic core releases negatively charged ions that help eliminate frizz and static electricity for easier hairstyling while evenly distributing heat for healthy looking shine, volume, and lift. The brush’s red bristles retain heat and the black bristles stay cool for precise styling control. With five temperature settings and auto shut-off. Plugs into AC. Gray. 14"L x 2 1/2" W x 2 1/2" D. (14 1/2 oz.)
