Dyson - Corrale Hair Straightener - Black Nickel/Fuchsia
Model: 322851-01SKU: 6401370Top comment"With coarse hair I found that it still worked best with 1 inch or so sections of hair at a time. I found with my unruly hair it couldn't handle much more than that without having to do multiple passes over the hair. it was better to do smaller sections of hair. ...It is indeed the best flat iron I have had. I wish it came in a 1 inch size to create tighter waves. It does not burn my hair at all, and it straightens / curls hair faster and easier. "

The Dyson Corrale straightener 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. 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.Top comment"With coarse hair I found that it still worked best with 1 inch or so sections of hair at a time.
