This straightener with Bio Ionic Moisturizing Heat technology gently styles hair and provides smooth, shiny styles and hairstyles with less damage. Plates infused with graphene, the world's best heat conductor and ion accelerator, heat up quickly and ensure even heat from root to tip. At the same time, Bio Ionic's own mineral mixture penetrates moisture into each hair strand and seals the cuticle layer. It allows you to create the styles you love again and again without compromising the health of your hair. This gentle straightener also has a smart function that automatically switches off the straightener after 30 minutes.
