RevAir is the fastest, healthiest, easiest way to dry and smooth hair in one step. NO STRESS. NO SWEAT. NO PROBLEM. Once you experience RevAir, you will never go back to blow dryers and hot tools that can cause heat damage and leave your hair brittle and lifeless. RevAirs friction-free reverse-air technology gently and effortlessly dries your hair from root to tip, while simultaneously smoothing strands without impact to curl patterns. Unlike anything you have ever used, RevAir draws hair into the Wand, using the power of reverse-air suction to create tension that aligns and smooths each hair strand. This unique approach saves you time and effort, reducing your drying time by up to 70% while preserving hairs strength, shine, color and overall health. RevAir has 7 tension settings to accommodate all hair types and is equipped with internal temperature sensors that maintain even heat (158F on low/220F on high), significantly below the temperature threshold of which hair is subject to heat damage. RevAir is currently approved for use in the USA and Canada. Operating outside of the USA and Canada will VOID the 30-Day Guarantee and Warranty.
