||Thermal damage measured by hair strength, when creating an equivalent hairstyle. Tested on flexing plates vs solid plates. Direct image analysis vs untreated hair. Exact run time depends on your hair and styling habits. The Dyson Corrale™ straightener is the only straightener with 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 damage. It also means enhanced styling, for reduced frizz and fewer flyaways. The Dyson Corrale™ straightener can be used corded, or cord-free to provide extra versatility and freedom while styling. Using a 4-cell lithium-ion battery, drawn from Dyson’s cord-free vacuum technology, it delivers up to 30 minutes of cord-free styling with the thermal performance of a corded straightener.
