10 Best Curling Irons, Tested by Beauty Pros

Temperature settings: Adjustable heat up to 450ºF | Barrel size: Available in 1" and 1¼" | Material: Titanium

Reaching the highest temperature in our tests, this curling iron came out on top in our tests for forming lasting curls, even on coarse, thick hair. It blew away the competition, scoring highest in nearly a dozen categories including grip and maneuvering, easy controls, compact size and producing curls that stay put.

Users loved "that the clamp is as long as the barrel," which is particularly useful for shorter hair, and the shorter handle length "keeps my hand in a perfect position to reach the thumb grip," although it may get a bit hot when set up to the highest temperature.

In Lab testing, we also found that it took longer than other curlers to reach the highest temperature (160 seconds), so just be sure to give it ample time to heat up before styling.

Temperature settings: Adjustable heat up to 400ºF | Barrel size: Available in ¾" to 1½" | Material: Ceramic

You can't beat the price of this classic and well-loved curling iron. Its bargain price is a huge selling point, and Amazon reviewers swear it's a worthy investment. It has adjustable heat and a ceramic coating, and for the price, it's a solid choice — just ask the almost 89,000 five-star reviewers who said it works great on fine and thick hair alike.

"The adjustable temperature settings provide flexibility, allowing me to choose the heat level that works best for my hair type," said one Amazon reviewer. "Whether my hair is fine or thick, I can achieve the perfect balance of heat without causing excessive damage." At such a bargain price, it may not last you for years and years, but it still does the job just fine.

Created by hairstylist Sarah Potempa, this time-saving, automated curling iron is the only one GH Beauty Director April Franzino uses (pictured), and it's also the go-to curling iron for Beauty Lab Senior Chemist Danusia Wnek as well — and that's saying a lot.

As someone with super-long hair, I often struggle with real estate on my curling irons; I'm always running out of space on the rod before I can reach the full length of my hair. This tool fixes that issue and works especially well for longer hair thanks to the extended length of the barrel, which is two inches longer than most curling irons. I love that the clamp runs nearly the full length of the barrel as well for fast, easy styling.

Fans say that their style lasts for hours, and one reviewer said her "curls last the whole day and I still can have loose curls the next day." While we think the long barrel is a brilliant solution for those with long hair, it may not be best-suited for those with shorter hair — and the long barrel can take some getting used to at first, too.

Temperature settings: Adjustable temperature 240ºF to 430ºF | Barrel size: 1 ¼" | Material: Ceramic

This clever iron is actually three tools in one: A flat iron, a curling wand and a curling iron. The 1 ¼-inch barrel is perfect for glam waves and curls, and our short-haired testers particularly loved it, saying "it was easy to maneuver and keep from touching the face or scalp," and that it felt the safest of all options with a low burn risk.

In Lab tests, it scored in the middle of the pack in everything from ease of use to performance to user satisfaction. While short barrel and compact design makes it foolproof to use on shorter tresses (and the perfect size for travel, too), the tool may be too short to use effectively on longer hair.

Temperature settings: Adjustable temperature 280ºF to 430ºF | Barrel size: Available in barrels ranging from ½" to 2" | Material: Steel with 24K gold plated

Scoring tops for easy maneuverability and ergonomic design, this curling iron is great for beginners — plus, it's budget-friendly if you're just getting into styling your own hair at home. Testers loved that "the clamp is long and clips hair well; it does not pinch it at the end," making it easy to use for novices.

This solid iron scored high in ease of use, performance and satisfaction in our tests and performed better than any of the irons we tested for creating curls that lasted throughout the day, which is perfect for thick hair that might typically be resistant to holding a style. It scored highest for releasing hair from the clamp without snagging or pulling hair, including a perfect score for its clamp.

Testers said, "the barrel is smooth and clip works well," though some found the thumb clamp tricky to press. This iron also reaches the highest temperature that we tested, a whopping 450ºF which is ideal for forming long-lasting curls in even thick, coarse, natural textured or hard-to-curl hair.

Temperature settings: Adjustable temperature 200ºF to 450ºF | Barrel size: Three attachments: 1" wand, 1 ¼" curling iron, 3-pronged waver | Material: Ceramic

Drybar's curling wand has performed well in our Lab tests, so it's no surprise this three-in-one pick is a fan favorite (it's also the only one I use at home!). In my experience, it heats up quickly on every mode and every barrel is smooth and snag-free for glossy, smooth styling.

The mechanism to switch the attachments is easy to use and feels secure and safe, while the display is bright and the rubberized buttons are intuitive and simple to press. It has three useful attachments for all of your curling needs and then some: A 1-inch wand for undone beach waves, a 1 ¼-inch curling iron for polished curls and a three-pronged waver for messy texture.

Plus, the clamp on the curling iron is heated so you can also use the larger barrel as a wand or a smoothing flat iron, of sorts. I do wish there was a better kickstand to keep the heating element from resting on the counter, and I find it's easy to accidentally turn off while styling sometimes.

Our Beauty Lab pros love the Dyson Airwrap: Like a hair dryer and curling iron in one, this high-tech styling tool uses six powerful streams of hot or cool air to magically style your hair from damp to dry.

Our Lab pros appreciate the genius air jet design, which makes hair strands, as if by magic, wrap themselves around the curler attachment. The result: Bouncy bends that rival a professional blowout. "It gives salon-level styling using lower heat, which can minimize damage as well," said one tester.

This sleek one-inch model has universal voltage and earned dozens of rave ratings from reviewers, including those with thin hair. "I have fine hair and it is wonderful to find a curling iron that actually does what I need it to," one Nordstrom reviewer said. We haven't Lab-tested this iron, but it's a consistent top-seller with a cult following (and a GH beauty editor fave!).

While no heat tool can be "damage-free," in our Beauty Lab's test of flat irons, we found that ghd's tools maintained a steady temperature of 365º which helps prevent excessive heat damage, unlike other models that can exceed 450º, so we expect the brand's curling iron to perform similarly. The downside, though, is that a single temperature may not suit all different hair types, textures and thicknesses.
