The Dyson Corrale  hair straightener has three temperature settings: 165°C, 185°C, 210°C. The optimum temperature for styling will depend on your hair type and the style you want to achieve. Extreme heat damage increases with the level of temperature you apply to your hair. We therefore recommend that you start at the lowest temperature and increase it if necessary.The flexible plates of the Dyson Corrale hair straightener allow you to achieve the same style but with less heat, and therefore half the damage.
