We've been waiting for a Dyson straightener since the brand dropped its Supersonic Hair Dryer back in 2018. And this month, it's finally here. The Dyson Corrale Straightener (£399) has revolutionary flexible metal plates, three temperature settings, and rechargeable battery with a detachable magnetic cord that gives you the option to go cord-free if you like. After seven years of research and £25 million of investment in research and development, Dyson promises that the Corrale reduces the damage to your hair by 50 percent as the flexible plates provide better distribution of force and heat every time you clamp down on a section.
