The Rosepal One-Step Hair Dryer and Volumizer are a designed Hot Air Brush to deliver gorgeous volume and brilliant shine in a single step. The unique oval brush design smooth hair while the rounded edges quickly create volume at the root and beautifully full-bodied curls at the ends in a single pass, for salon blowouts at home. The brush is designed with Nylon Pin and Tufted Bristles for detangling, improved volume and control. Styling flexibility is guaranteed with 3 Heat/2 Speed Settings. Built with 1000 Watt power to provide just the right amount of heat. Unlike conventional hair dryers, this volumizer can be placed closer to the scalp for lift. Boosted by Ionic Technology through a built-in genuine ION generator, hair dries fast and helps reduce heat damage. The One Step Unit is designed for 110/120V or 200/220V outlets, we do NOT recommend the use of a Voltage Converter as it will damage the unit. Safety first!
