The 12 Best Curling Irons for Easy Styling

1. Temperature is important. “People assume, ‘If I do the highest heat setting, it will last,’ which is 100% not the case,” Polko says. “When you crank it up all the way, you’re actually zapping your hair too much, and it doesn’t know what to do. It’s like putting it in a microwave versus an oven. You’re letting the heat get into it, and it’s more of a gentle heat, so that actually will help the style last longer if you have it on a lower heat setting.”

In general, the thicker the hair, the higher the heat setting, and the finer the hair, the lower the heat setting you should use. You should also keep things like color and chemical treatments in mind when choosing your heat level. Polko recommends the T3 Curl ID curling iron, which we used for the tutorial. “It takes the guesswork out of picking the right heat for your hair type! You just put in your hair texture, color treatment, and chemical treatment, and the Curl ID will pick the right heat setting for you depending on these factors.”
