Midnight Heat uses negative ion technology to keep hair shinier, smoother and frizz-free. The digital read ensures the temperature is just right and optimized for each specific hair type. With black tourmaline ceramic floating plates that heat up to 450°F, dual voltage, auto shut-off and a 9’ cord, there is no strand that this flat iron can’t straighten. Adjust temperature to heat levels appropriate for thickness of hair shaft (fine hair at 350°F/175°C, coarse hair at 450°F/230°C). Glide through sectioned pieces of hair to straighten or curl.
