The Revlon Pro Collection One-step dryer and volumiser brush has been design with a unique oval brush that helps to smooth the hair and create volume at your roots. This quick and easy volumiser uses ionic technology which uses negative ions that saturate airflow to reduce the size of water droplets for rapid drying. Ionic technology works to condition, smooth and give your hair a beautiful shine whilst also working to reduce fix and static. The Revlon Pro Collection One-step dryer and volumiser brush comes with nylon pin bristles and boar bristles that softly detangle your hair whilst also helping to grip on curved edges for improved volume and shine.
