This is the rotating brush that reduces styling time by 50%. It comes with two interchangeable brush heads (flat and 1 1/2" diam. round) that affix to a tourmaline ceramic coated heating center, allowing you to style and dry hair at the same time. Its core releases negatively charged ions that break down water droplets to increase the rate of evaporation, helping to eliminate frizz and static electricity for easier hairstyling. The motor blows air through the brush and enables you to rotate the round brush head 360° with the touch of button. With three temperatures settings and a protective cover. AC plug. 14" L x 4 3/4" W x 3 1/2" D. (1 1/2 lbs.)
