Tourmaline, a pure, precious gemstone, is a natural source of negative ions and far-infrared heat. Negative ions eliminate frizz and close the cuticle to create silky, shiny hair. Negative ions also break apart water molecules more quickly, reducing drying time for moisture rich hair. Far-infrared heat penetrates hair from within, resulting in faster drying time with less damage. Ceramic distributes high heat evenly. With 6 heat and speed settings and a cool shot button this hair dryer is versatile for every hair type. Babyliss Pro diffuser sku # A8582 can be used with this dryer
