The RX7 Advanced Ionic Styling tool is faster and makes hair visibly shinier. One pass and done. Floating Tourmaline plates compress your hair while styling acting as a cushion. Curl, flip, style, straighten are a breeze. The Tourmaline Ionic emits the largest amount of negative ions and infrared heat. Infrared Technology allows heat wavelengths to penetrate directly into the hair which means less time spent on styling, less heat exposure and less hair damage. 1 1/4″
