What it Does The patented DevaFuser® helps dry your curls with gorgeous shape, definition, and touchable volume. The innovative 360-degree airflow surrounds curls and gets right to the roots (where it takes longest to dry) for speedier drying time than traditional diffusers. And the Ceramic inner core helps preserve moisture to reduce frizz and enhance shine. Fits Hair Dryers Size: Barrel Diameter 2” – 2 ½” Barrel Circumference 5½” – 6 ½”, and Barrel Length 2 ½” – 6 ½”. How to Use 1.Attach the diffuser to the end of the dryer nozzle and turn on. 2. Set your blowdryer with either Medium or Low Heat. This is to protect your hair scalp, avoid overheating, and is the best temperature for curls. It also protects the attachment. 3. Hold near the scalp to dry the roots. 4. Cradle the ends of curls and push toward the scalp to scrunch and hold. Concerns: Curl Enhancing Brush + Comb Type: Styling Combs Country of Origin: Imported
