The T-Curve Range combines the popular triangular, 3-sided brush design with a curved shape in the center of the barrel. This allows the barrel more contact with the hair, maximum control and greater volume. The triangular design offers flexibility for tension control as you can use the brush like a round brush, rotating through the hair, or as a flat brush. It achieves better results in less time. The Creative T-Curve brushes have a Tourmaline Ceramic finish with negative ion technology which help promote healthier results and a shinier finish. The medium size is good for medium to long hair types.
