What it Does The Porcelain Ceramic™ technology in our straightening irons distributes even heat across the plates and generates far-infrared heat, a more efficient heating method which is gentler to hair. Rheostatic dials let you select desired temperatures up to 450°F and the ceramic heater provides instant heat-up and recovery, while the longer plates allow you to work faster with wider sections. The result is smooth, sleek and healthy-looking hair!
