You can create every size curl you can think of with a Hot Tools Professional Spring Curling Iron. Each curling iron model features 10 variable heat settings for ultimate curl control, a 24K gold plated barrel, and a powerful spring clamp to set each curl with long-lasting hold, and all Hot Tools professional spring curling irons have a Patented Pulse Technology for Gets Hot... Stays Hot performance. From tight corkscrews, to large bouncy curls, to loose waves (and everything in between) you can’t go wrong with Hot Tools. All you need to do is pick your barrel size. We suggest 2” for medium or long hair and extra large, loose curls and waves. This large barrel size is also great for adding volume and lift at the roots.
