The sensor technology protects the moisture balance of your hair. The sensor analyzes your hair 30 times per second and adjusts the temperature accordingly to maintain natural moisture. It preserves up to 57% of moisture. Thanks to the powerful heating element, the warm-up time is only 15 seconds. The hair straightener provides a consistent temperature for even results. Negatively charged ions eliminate static electricity, nourish the hair, and smooth the outer cuticle layer for shiny hair. The result is healthy, shiny, straight hair. The Philips hair straightener features 3 digital temperature settings (200, 175, and 150 °C), which are controlled by a sensor, allowing you to straighten your hair at the optimal temperature. The flexible plates adjust the pressure to the hair, protecting it from damage and reducing the risk of breakage.
