Straightener, Protective Keratin, Integrated digital display: 5 heat settings 160 - 230 ° C, Extra long plates of 110mm, Hot in 15 seconds, 5 year guarantee No more bad conscience when straightening your hair! Our keratin coating straightener is the ultimate in hair protection. This amazing straightener combines ceramic keratin sheets with an exclusive heat-protecting sensor and therefore you get two amazing features in one. The keratin is transferred to the hair when the plates are heated and not only provides a protective film around the hair, but it also makes your hair soft and shiny. The heat protective sensor is built into the plates to give each hair strand extra protection. The sensor detects the moisture level of the hair and adjusts the flat iron's temperature to it.
