The Andis Elevate 1� Tourmaline Nano-Ceramic Flat Iron has 20 variable heat settings for all hair types. Crushed from precious gemstones, the tourmaline crystals emit negative ions that quickly seal the cuticle layer and eliminate frizz for smoother, silkier hair. Ionic technology dries hair faster by breaking up water molecules. Nano-Ceramic, with it�s smooth finish, minimizes friction and delivers far-infrared heat. It penetrates the hair from the inside out, for deep, long-lasting styles. The fusion of nano-ceramic and tourmaline straightens hair in less time and without typical iron damage. Hair is left softer and shinier. You can straighten, flip, shape, control, and smooth hair with a single product. The maximum temperature of 400 degrees allows you to really lock in the style. Designed and engineered in the United States, Andis also offers a complete line of quality clippers and trimmers for consumers and animal grooming as well as a full line of wall mounted hair dryers for the hotel industry.
