what temperature do you iron hair
According to Dr. Moore, all those temperature settings on most flat irons are unnecessary â 365 degrees is hot enough that youâll only need one pass through your hair with the flat iron to get your desired look. Styling at temperatures above 365 degrees exposes hair to unnecessary heat,â he explains. âAnd at temperatures above 420 degrees, the keratin protein in the hair starts to melt, causing irreversible damage.â
