T3 SinglePass Curl X Extra-Long Barrel Curling Iron with 9 Heat Settings and Ceramic Barrel for Fast Styling and Lasting Results on All Hair Types

Why it's worth it

The T3 SinglePass Curl X pairs a 1.25-inch ceramic barrel with nine heat settings, so you dial the temperature to your hair instead of guessing at low, medium and high. The barrel runs extra long, which means fewer passes and less total heat on long hair.

Nine heat settings are the reason to buy this one. Most irons hand you a vague dial and let you sort it out. If your hair is fine or color-treated, Healthline's guidance says stay at or below 350°F. If it's coarse, Allure's stylist consensus puts you closer to 375°F before a curl will hold at all. Stepped digital settings let you find your number once and come back to it every morning.

The barrel is long, and that quietly changes how a morning goes. The tool measures about 13.6 inches end to end, so you can feed a wider section in and cover it in one wrap instead of three. If your hair falls past your shoulder blades, that's the difference between twenty minutes and ten. It also makes the back of your head much less of a fight.
