Of the hundreds of hair sets available on the market, only a handful offer solid Tourmaline and Ceramic. Nearly all use metal plates coated in a thin layer of ceramic. 100% solid ceramic and Tourmaline is the only materials that provides the highest hair protection from frying and burning your hair. The KOR Ceramic Irons and Tourmaline Curlers is 100% true, solid Ceramic & Tourmaline not coated. It's plates will never peel or chip or expose your hair to damages like irons with metal plates. KOR Professional Products features the best possible heat distribution and retention. Solid Ceramic & Tourmaline plates also have 100 times more negative ions than ceramic-coated plates. Why is that important for the health of your hair? Damaged hair is positively charged - from static electricity, chemicals in styling products or use of metal-heated hair tools. The positive charge keeps hair follicles open, dried out and brittle. Negative ions neutralize the positive charge, closing hair follicles and smoothing the hair shaft. They actively condition the hair and shine it, while eliminating frizz and static. The result is hair that is shinier, more nourished and healthier than before. That is why KOR heat is healthy heat.
