The Professional Brush Curling Irons from Helen of Troy have been designed and tested for performance, durability and handling ease. With a lifetime heating element and strip bristle design, long lasting results are guaranteed. The ergonomically designed handle is contoured and comfortable so you can create an abundance of classic curls. We suggest 1-1/2” for medium to long hair and big, loose curls. This large barrel size is also great for adding volume and lift at the roots.
