Tourmaline is an organic, prismatic crystal found in granitic rocks that is crushed into a fine powder and layered onto the surface of the plate. Tourmaline is great because heat is more consistent and evenly distributed through the plate. Also, it produces more negative ions than ceramic with less heat. This means that you not only get more control, but you also get better results and expose your hair to less damage. It’s the newest entry in the heat styling industry so hair straighteners with tourmaline tend to be pricier. Some hair straighteners like the HSI Professional Glider infuse both ceramic and tourmaline to boost the number of negative ions produced.
Great straighteners first pair for the missus and I think she is hooked. Loves the quick best up and thermal trip feature.
