What it Does The Hot Tools Nano Ceramic product line features the best of the best ceramic hair waver. Designed to help protect hair from overheating, to keep hair integrity intact and help minimize hair damage. Nano-size particles of ceramic create an ultra-smooth Micro-Shine snag-free surface allowing hair to effortlessly glide across the styling surface with less pulling just styling, leaving behind smooth and shiny strands. A rheostat temperature control dial allows you to easily switch between heat settings. Heats reach up to 430F which means perfect curls and waves for all hair types. And, thanks to HOT Tools? proprietary Pulse Technology, these irons get hot and stay hot. In the event of a momentary temperature drop, the tool senses the shift and restores it immediately, so the iron stays hot for consistent styling. The 8ft. professional swivel cord allow for free range of movement. And, a 7-year limited warranty provides added value. How to Use Starting at the roots, lightly clamp a small section of hair betweeen the barrels and hold for a few seconds. For continuous waves, match the outermost wave and work it down the hair.
