Wavytalk 1.5 Inch Purple Ionic Thermal Brush This 1.5" diameter thermal brush is great for creating a "dry blowout" by smoothing and adding volume, bounce, movement, and loose curls. It has a negative ion function to lock in moisture, smooth the hair, and reduce frizz. It has a ceramic barrel, two heat settings (350F and 410F), a 360 degree swivel cord, and 120V-240V dual voltage, so you can use it outside the US (with a plug adapter, not included). Used once. Note: this does not blow hot air and is not a wet-to-dry styler. Like any higher heat styling tool, always start with fully dry hair and use a heat protectant designed for use with hot tools to avoid damage. Smoke-free, pet friendly home. Got questions?
