The Dyson Corrale Straightener (Prussian blue/rich copper) is the only straightener with copper flexing plates that shape around your hair, gathering it neatly together on each pass. This extra control means you can achieve the same style but with less heat – and therefore half the damage¹. It also means enhanced styling, for reduced frizz and fewer flyaways². The plates are made of manganese copper, selected for its flexibility, strength and thermal conduction. The Dyson Corrale straightener can be used corded, or cord-free to provide extra versatility and freedom while styling.
