    "As a Competitive dog groomer that doesn’t always have access to power, having a flat iron that is wireless is amazing. This product hits all the high points!"

    See all customer reviews

    Product Description

    This product has been refurbished. The Dyson Corrale Refurbished straightener is the only straightener with copper flexing plates that shape around your hair, gathering it neatly together on each pass.

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. ¹Thermal damage measured by hair strength, when creating an equivalent hair style. Tested on Corrale with flexing plates vs Corrale with solid plates ²Direct image analysis vs untreated hair. ³Exact run time may vary based on hair type and styling technique.
