Tourmaline is a precious stone that's ground into a fine powder, then infused into the ceramic plates of a tourmaline flat iron. Its high negative ion output creates sleeker, shinier, frizz-free hair. The tourmaline flat iron has surpassed ceramic as the most advanced professional hair straightener in the salon industry; similar results can also be seen from a titanium flat iron. Try tourmaline hair dryers, curling irons and even brushes to maximize the effect of your tourmaline flat iron!
