As someone whose hair is naturally poker straight, anything that promises to give it some volume and curls is always of interest to me. This thick 32mm iron aims to create large, bouncy and long-lasting curls. This iron has a clipless design that provides a consistent, even heat without causing dents or crimps in the hair or snagging inside the mechanism. It also reduces heat at the end of the iron to protect the hair’s most delicate area, the tips, from heat damage.
