What it is: A professional styling brush designed with a vented body and a paddle shape. What it does: It allows air to circulate freely for fast blow-drying. How to use: Detangle damp hair using the Dry Vent Brush. Rough-dry hair until it's 80% dry. Place the brush underneath a section of hair at the roots and pull down, directing the airflow of the dryer at the brush. Continue until you achieve your desired look.
