Testing notes: “Although there’s a lot of it, my hair is very thin and flat, so I’m no stranger to using a hot tool that sometimes makes it sizzle (though I do whatever I can to avoid that). This straightener takes the guesswork out of it because it has a wide temperature range that you can easily adjust, and the plates themselves never get overly hot, even if you crank it up a bit. The ceramic material and aloe vera coating keep them relatively cool but don’t get in the way of styling. After using this for a few sessions, my hair looked smooth and velvety, and I only had to go over each section with two passes. If you have fine, thin strands, this one is worth the try, for sure,” says Glamour’s Kilkeary.

  • What we love: Makes hair shiny and soft; extremely affordable
  • What could improve: Material is a little cheap

We found this straightener while browsing an Amazon bestseller list, and knew we had to give it a go. This compact option heats up to 450°F for a sleek finish. The plates are also infused with argan oil to give your hair some extra shine.

Testing notes: “Sometimes if I go to bed with my hair wet, it ends up frizzing by morning. This means I need a quick fix to smooth out my tresses before I’m headed out. This straightener does just the trick in just a few swipes to kill frizz and flyaways, and I’m always left with shiny, strong-looking strands. It’s definitely straightforward and no-nonsense, and good for those with thin strands that need more of a touch-up, in my opinion,” says Glamour’s Kilkeary.

  • What we love: Ultrasmooth glide; delivers a sleek and shiny look in just one or two passes; shuts off after just 10 minutes
  • What could improve: Cannot control temperature manually; not as well-suited for curling

We’ve long been fans of GHD’s flatirons—one of the brand’s longer-standing models, the GHD Platinum, won a Glamour Beauty Award in 2020. And we’re pleased to say this one is even better. Yes, the price tag is steep (very steep), but there’s really no guesswork here, and even Rogerio Cavalcante, hairstylist and owner of the Second Floor Salon in New York, shares that this is one of his favorites. There’s no temperature to choose from; instead, it’s a smart iron that uses predictive technology to recognize the thickness of your hair and the speed at which you’re styling. It then adjusts its power accordingly, operating at an optimum temperature of 365°F.

Testing notes: “In tests we found that GHD’s Chronos Styler heated very quickly, plus it emits a satisfying ping to alert you that it’s ready to use. We also appreciate the 10-minute auto shutoff, which is much faster than all of the other products we evaluated—a nice safety feature. On the downside, I didn’t have as much success curling my hair with this flatiron, despite the rounded edges—and I’d consider myself pretty advanced in this department. I did, however, successfully execute a sleek, straight style with plenty of shine and the type of rounded ends you might get from a blowout,” says Earley.

  • What we love: Extra-smooth plates; easily available (on Amazon); gives hair a high-gloss finish; has dual voltage
  • What could improve: Can singe hair if heat is too high

This flatiron keeps hair frizz-free and shiny post-straightening and has a wide temperature range with easy-to-adjust heat settings. It has an easy-to-read LED screen as well.

Testing notes: “I recently cut my hair short at my shoulders,” says Glamour’s Kilkeary, “so I was looking to test a new straightener with extra-smooth plates to get a uniform straightened finish (without making my strands looking stringy or greasy, which can sometimes happen when my oily hair gets cut). This straightener did just that, and made my hair look even in length and non-oily in finish. Although I’m not at a bob level of short, this straightener did my shoulder-length style justice.”

  • What we love: Ceramic plates are gentle on hair; can be used on wet or damp hair
  • What could improve: Pricey; heavy

Multistylers are all the rage, especially if you’re looking to invest in a hot tool without fully breaking the bank. This eight-in-one option has a ceramic flatiron attachment that can be used on wet or dry hair and makes it easy to customize your look, whether you want a pin-straight finish or straight hair with curled ends.

Testing notes: “If you want a multistyler that does it all, this is the only tool you’ll need. The best way to use it is to take advantage of all the styling heads. My hair is wavy, and after showering it gets puffy and frizzy, so I normally style it right away. In order to get a quick sleek look, I use the air brush and then finish with the iron. It heats up fast, doesn’t burn my strands, and keeps it straight for days later,” says Glamour senior commerce editor Jenifer Calle.


Other hair straighteners we tested

  • Conair Double Ceramic Flatiron: It heats up to 410°F, so it’s suitable for all hair types, from fine to coarse and curly. But the heat settings weren’t quite as numerous as some other more sophisticated models. We were impressed with the $25 value, but it would have been nice to have a longer cord and, more importantly, an auto-shutoff feature.
  • Dyson Corrale Hair Straightener: Glamour tester Gabriella Cuzzone was a big fan of this straightener because its cordless and “it heats up wildly fast.” The downside: “On the lowest heat setting, I had to run the straightener through my hair several times over,” she says.
  • The CHI Original 1-Inch Ceramic Hairstyling Iron: It’s a bestseller and worked well on our testers, but we found that it doesn’t heat up as much as others on the list for the price. “While it did take approximately two solid passes per section to straighten my hair, the end result was nice and sleek while still maintaining some volume,” says Earley.
  • Drybar The Tress Press Digital Styling Iron: Glamour commerce director Brie Schwartz has owned this straightener for more than five years and is a fan of how straight it gets her 3C curls. “I’ve been using a flatiron for over 25 years, and I’ve tried at least 10. I used to be loyal to the popular GHD, but I find the Dry Bar option is even better for my fine, midlength, curly hair since it has a narrow barrel and is super lightweight so my wrists don’t hurt after a styling sesh. This has by far been the easiest to work with. It has stayed in great shape, and despite my dropping it countless times, it hasn’t broken. The one thing to note is that, after about a year, the outside started getting hotter to the touch, so I’ve had to to be careful about how I grip it.” Schwartz also likes the digital temperature control that lets you know what temperature you’re operating at, up to 450°F.
  • Bio Ionic Onepass Styling Flatiron: We liked this iron because the plates are quite thick, and it’s gentle on hair thanks to its ceramic finish. “I have very thick hair, but luckily with this hair straightener, I didn’t have to do so many passes the way I do with other flatirons. I haven’t noticed any serious hair damage, and my hair stays super straight for days,” says Calle.
  • Hot Tools Pro Signature Dual-Plate Flatiron: A smaller plate size (between ½ inch and 1 inch) is best for shorter hair, and this Hot Tools flatiron can help you get an ultrasmooth finish. “The dual plate was very cool (which allows you to iron bigger sections of hair), though the ability to heat up each plate individually was a nice feature. I’d definitely use it again at a higher heat,” says Condé Nast content licensing associate Paton Hardy who has fine, curly hair cut at a short length.

    Frequently asked questions

    What to look for in a hair straightener, and what straightener do hairdressers use?

    When choosing a hair straightener, there are a few things to look out for, according to Cavalcante, whose favorite hair straightener is the GHD Chronos Styler 1-Inch Flatiron. Consider the following attributes.

    Temperature range: “Choosing the right tool really depends on your hair texture, density, and the style you’re going for, but temperature is an important factor to always keep in mind,” he says. If you have fine or fragile hair, opt for straighteners that have a lower temperature range (around 250°F–300°F). If you have thick or coarse hair, reach for a tool that has a higher temperature (up to 400°F). “Use wider plates to cover more hair at once, and always work in smaller sections so the heat can reach all strands. “Finally, if you have textured or curly hair, you can use straighteners at higher temperatures, but it’s important to use heat protectants and avoid going over the same sections multiple times,” he says.

    Material: Ceramic plates are good for fine, thinner hair, while titanium plates are good for thick and curly hair

    Ease of use: No matter what your hair type is, Cavalcante recommends picking a tool that feels good in your hand: “You want your straightener to be comfortable, not too heavy and easy to maneuver.”

    Performance: We looked for straighteners that heated up quickly and left our hair smooth, silky, and frizz-free after use

    Features: Cord length and customizable heat settings that didn’t get overly hot

    How do you choose the best hair straightener for your hair type?

    There are two main types of hair straighteners: those made with ceramic plates and those made with titanium plates. Less commonly, some flatirons feature a combination of the two. There are also outliers, like the Airstrait, which use air rather than hot plates.

    For fine or relatively easy-to-straighten hair: Set your sights on a flatiron with ceramic plates, since this material takes longer to heat up and has more-even heat distribution, says Raven Hurtado, a hairstylist at Maxine Salon in Chicago. Sometimes you’ll find ceramic tourmaline options; these offer added hair care benefits, since tourmaline is a mineral that helps smooth and boost shine while locking in moisture, helping to minimize both frizz and static.

    For coarse or curly hair: A titanium flatiron may be preferable for these hair types, since this material heats up faster and can maintain a higher temperature that requires fewer passes on the hair, says Lacy Redway, Unilever stylist and celebrity hair artist.

    What temperature setting should you use in a flatiron?

    Fine to medium hair: Experts recommend lower temperature ranges of 250°F to 300°F.

    Curly to coarse hair: Experts recommend staying within the 350°F to 450°F range. But you’ll want to use a protective spray or serum beforehand and smoothing oils afterward to balance out the extreme heat.

    Colored or damaged hair: Experts recommend using heat sparingly, as bleaching and highlighting dries out and damages hair—and if you do use heat, stick to the lower ranges of 250°F to 300°F.

    How to prevent hair damage when using a flatiron

    The hotter your setting, the more likely it will damage your hair—no matter what type of straightener you’re using. After all, you’re applying direct, intense heat to your hair. Always apply a heat protectant before you begin, and choose a safe temperature (as outlined above) for your type of hair, says Redway. Our favorite heat protectants to use are the Dae Agave Dry Heat Protection Spray and the Amika Blockade Heat Defense Serum.

    Are titanium or ceramic plates better?

    While no material is necessarily better than the other, you’ll want to choose between ceramic and titanium straighteners based on your hair type. “Look for ceramic plates, which will heat more evenly and gently if you have fine or damaged hair,” says Cavalcante. Thick, coarse, and textured hair types can take titanium tools because they get hotter more quickly, retain this heat for longer, and can even help speed up your straightening process. To ensure that you don’t damage your hair, though, it’s important to always use heat protectant and limit usage to twice a week, max. “If you feel like you need to flatiron your front pieces every day, consider a more permanent option like a Brazilian blowout or a keratin treatment,” Cavalcante says.

    Can you use a flatiron to make curls?

    “To create curls with a flatiron, clamp the top of a section of hair between the plates, twist the iron once, and glide it down. The angle at which you hold the flatiron affects the curl type—holding it horizontally creates tighter curls, while a diagonal angle results in looser waves,” says Cavalcante.
