The Smart Curling technology consists of three elements: auto-rotation, ceramic coating and ions. The automatic rotation function allows your hair to be drawn into the curling chamber, where it is gently held and heated from all directions, so that you get flawless curls or waves. The ultra-smooth ceramic coated interior prevents your hair from getting overheated, tangled or damaged. Finally, the ion technology ensures an antistatic effect by producing negative ions, which means that even dry or damaged hair becomes frizz-free, silky and shiny.
