When you're looking for a great curling iron, temperature capabilities, barrel size, and what it's made out of are all really important factors. But for a lot of people, a clamp is a deal breaker. While some people prefer clipless irons,the best curling irons with clamps hold your hair in place while you style it. So, if that glove intimidates you or your hair is always slipping off the barrel, these are the irons for you.
Many people don't realize that the terms "wand" and "iron" are actually not interchangeable. A curling wand and a curling iron are two different tools, and this is primarily due to the clamp. Because of this one simple feature, you hold the tool differently, and you're left with two different results. An iron with a clamp gives you ringlets, while a wand without one gives you curls that are closer to waves. If you're looking for actual curls, the clamp is a good way to go.
That being said, curling irons with clamps come in all different shapes, sizes, and designs. There are tapered ones, travel sized, thick, thin — you name it. All that's left is to find one that fits your hair and your needs.
