The Keratin Therapy Pro Hair Straightener S8590 exclusively uses Keratin Protection Technology, which protects the hair from heat. The styling plates are equipped with a high-quality keratin ceramic coating. In addition, an innovative heat protection sensor constantly regulates the temperature to reduce hair damage during use. A digital display with 5 different temperature settings and a heat-up time of just 15 seconds round off the functions of the Keratin Therapy Pro Straightener S8590.
