You've likely been warned about the damage that can be caused by spending too much time flat ironing—or using blow dryers, diffusers, and straightening brushes, for that matter—your hair into the sleek style of your dreams. But, in 2024, there are more options than ever that let you have the smooth strands of your dreams, without having to sacrifice the health of your hair.

Best Hair Straightener

How to find the right straightener for your needs and preferences, you may ask? Don't worry, we took that into our own hands. The editors at Women's Health, along with a hairstylist, have tested and used more hair straighteners than we can even count. So, we got together and compiled a list of our favorite options and got to re-testing all of them. After months of using all the straighteners, we compiled a list of the absolute best seven for all hair needs. Keep reading to learn how we tested them, what to consider when shopping, and, of course, to discover our final list of favorites.

What to consider

Plate material

One of the very first decisions to make when looking for a flat iron is what material you prefer for your hair type (and, which one will cause the least amount of damage on your hair!). After testing, we determined that our three favorite materials are aluminum, ceramic, and titanium. We found that ceramic hair straighteners are the most common and they tug on the hair the least, so they're great for those of you with finer hair or strands that are color treated and therefore more at risk for damage.

On the other hand, titanium straighteners reach the highest temperatures, making them ideal for thick, coarse, or curly hair that needs extra heat to straighten. Although there's only one aluminum straightener on our list, it earned our Best Overall title, so you know it's a favorite. Aluminum plates are incredibly lightweight and durable, making them perfect for those who want something long-lasting and easy to hold.

Temperature

The key with finding a good straightener, according to celebrity hairstylist Justine Marjan, is to look for irons that are able to hold consistent temperatures and distribute heat directly into the strand. “Some irons don’t have consistent heat temperatures, or they quickly lose heat on the hair, then take time to reheat. This can result in uneven styles that fall and don’t last,” she explains. The good news? All of the fifteen selects below use technology that keeps heat even and many also feature multiple heat settings.

And get this hot tip: Keep the heat as low as you can—especially if you color your hair. “If a flat iron gets too hot, it can alter your hair color! Long term styling with an iron can not only cause damage to the hair but it affects its porosity, which means your color can slip out of your strands easier and therefore will fade faster, says Marjan.

Maneuverability

Speaking of ease of use, it's important that your straightener is easy to maneuver around your head. This means it shouldn't be too heavy (all the options on this list weigh under 2.5 lbs) and should have a long cord, so you don't struggle to reach the back of your head. Trust me, nothing's worse than dealing with a short cord or constantly needing to rest your arms.

So, are you ready for sleek strands without the damage? Read on to meet your perfect match.

Best Overall Hair Straightener

Ghd Platinum+ Professional Performance 1"

Pros
  • Beauty Experts Tested Dozens Of Hair Straighteners—These 7 Came Out On Top (10)Straightens hair very fast
  • Beauty Experts Tested Dozens Of Hair Straighteners—These 7 Came Out On Top (11)Super high-tech
  • Beauty Experts Tested Dozens Of Hair Straighteners—These 7 Came Out On Top (12)Evenly distributes heat to the hair
  • Beauty Experts Tested Dozens Of Hair Straighteners—These 7 Came Out On Top (13)Turns off automatically
  • Beauty Experts Tested Dozens Of Hair Straighteners—These 7 Came Out On Top (14)Works wonders on even the curliest of hair
Cons
  • Beauty Experts Tested Dozens Of Hair Straighteners—These 7 Came Out On Top (15)Not the best option for fine hair

We tested tons of straighteners, and out of every one we tried, the ghd Platinum+ Professional Performance straightener came out on top as our best overall pick. Why? It works on all (yes, all) hair types and textures to smooth, de-frizz, and add shine.

According to senior beauty editor Danielle Jackson, who has naturally coily hair, this is one of her favorite straighteners she's tested this entire year. Although it's a little pricey, she says it's so worth it when you consider the features: It heats up within 10 to 20 seconds, only has one temperature (365 degrees, which is just high enough to straighten out any kinks or curls without doing too much damage), and it automatically shuts off after 10 minutes of inactivity. "So, you don’t have to spend your commute panicking about whether or not you unplugged your flat iron after you’ve already left your house," Jackson says.

After testing tons of straighteners, we also concluded that the Ghd styling wand is one of the highest-tech tools on the market. It checks its own temperature a mind-blowing 250 times per second (!!) to ensure heat is being evenly distributed across both of the two plates. This technology claims to keep hair stronger, shinier, and double color protection. Even crazier? It recognizes hair’s thickness and the speed at which you’re using it and adjusts accordingly to provide the best results. After testing it, we noticed our hair straightens faster than it does with other options on this list.

We also tested this straightener on fine hair and found it might run a bit too hot for those with less hair. While it does straighten quickly, it gets pretty smokey and may be too hot of an iron for finer hair types.

Pros
  • Beauty Experts Tested Dozens Of Hair Straighteners—These 7 Came Out On Top (17)Like a blowdrier and straightener in one
  • Beauty Experts Tested Dozens Of Hair Straighteners—These 7 Came Out On Top (18)Makes hair feel super smooth
  • Beauty Experts Tested Dozens Of Hair Straighteners—These 7 Came Out On Top (19)Speeds up dry time on thicker hair
Cons
  • Beauty Experts Tested Dozens Of Hair Straighteners—These 7 Came Out On Top (20)Takes a few tries to get the pressure right

With five heat settings ranging from 260-410 degrees, plus wider plates (1.5 inches to be exact), this powerful straightening iron speeds up the process of styling thick hair. And, WH assistant social media editor Isabelle McMahon has proof.

"I have thick, slightly wavy hair, and most straighteners just don’t get hot enough to glide through it quickly," she says. "However, the T3 handled it perfectly, and my hair felt super smooth afterward." She notes that it took a few tries to get the pressure right so it wouldn’t pull her hair, but once she figured it out, it was so easy to use. "It's definitely a game-changer for my hair routine," she says.

Like the Ghd straightener, this tool is very tech-forward. It straightens hair in a flash, thanks to a fan that propels a wider airflow to significantly reduce dry time—it's almost like a blowdrier and a straightener in-one. And get this: It also features an ion generator, which infuses hair with negative ions to banish frizz and boost shine.

Unlike the Ghd option, which only has one heat setting, this straightener has nine heat settings so you can choose your own adventure depending on your hair type and texture. Plus, it's two ounces lighter. If you're looking for a customizable tool that saves time in your daily routine, this one is for you.

Most Customizable Hair Straightener

Amika The Confidante Moisture Maintenance Styler

Beauty Experts Tested Dozens Of Hair Straighteners—These 7 Came Out On Top (21)

Pros
  • Beauty Experts Tested Dozens Of Hair Straighteners—These 7 Came Out On Top (22)Many heat options
  • Beauty Experts Tested Dozens Of Hair Straighteners—These 7 Came Out On Top (23)Great for all hair types
  • Beauty Experts Tested Dozens Of Hair Straighteners—These 7 Came Out On Top (24)Penetrates heat deep into the hair with infared light beams
Cons
  • Beauty Experts Tested Dozens Of Hair Straighteners—These 7 Came Out On Top (25)Gets very hot and can damage finer hair
  • Beauty Experts Tested Dozens Of Hair Straighteners—These 7 Came Out On Top (26)On the heavier side

McMahon also tested the Amika straighter, and one of her favorite parts about it is that it heats up super quickly and makes her hair smooth in one pass. "I only needed to pass through my hair once for it to be silky and smooth, which is impressive because, with my hair texture and thick waves, it usually takes a few tries," she says, adding that she can def tell the difference between this and the cheaper tools she's bought before.

She also notes how easy it is to check the temperature setting on this tool, thanks to the digital screen that clearly displays it. And, speaking of temp, it goes all the way up to 490 degrees, so you can bet this tool straightens the hair super fast. And, to make matters even better, it has an infared light beam within the titanium plates to deeply penetrate the hair with heat.

Similar to the Ghd tool, it'll automatically shut off after 60 minutes so you don't have to worry when you forget to turn it off. Also like the Ghd tool, it can get super hot for finer hair. But, thanks to its customizable heat settings, you can turn it down to 360 degrees and below if you have thinner hair, which we appreciate.

One thing to note: It's slightly on the heavier side, so it's a bit harder to hold over your head than the others on this list.

Best Three-In-One Hair Straightener

Kristin Ess 3-in-One Titanium Flat Iron Hair Straightener

Beauty Experts Tested Dozens Of Hair Straighteners—These 7 Came Out On Top (27)

Beauty Experts Tested Dozens Of Hair Straighteners—These 7 Came Out On Top (28)

Pros
  • Beauty Experts Tested Dozens Of Hair Straighteners—These 7 Came Out On Top (29)Delivers heat to the hair in a flash
  • Beauty Experts Tested Dozens Of Hair Straighteners—These 7 Came Out On Top (30)Made with a rounded body for many different styles
  • Beauty Experts Tested Dozens Of Hair Straighteners—These 7 Came Out On Top (31)Titanium plates decrease frizz and add shine
Cons
  • Beauty Experts Tested Dozens Of Hair Straighteners—These 7 Came Out On Top (32)Doesn't glide as well as other options on this list
  • Beauty Experts Tested Dozens Of Hair Straighteners—These 7 Came Out On Top (33)Heavier than other options

Celebrity hairstylist Kristin Ess wanted one tool to do it all—so she created it for her eponymous hair care line. This iron is designed with a rounded body to make it easy to create four of her go-to looks: sleek straight, S-waves, and even polished curls.

So, yes—this do-it-all tool not only means more space in your drawer, but it also offers many different hairstyles for all different textures and hair types. Plus, the gold metal titanium plates deliver heat to the hair in a flash, so you don't have to spend too much time on your strands. They also deliver negative ions to the hair, which help lock in moisture, decrease frizz, enhance shine, and offer overall healthier-looking hair.

Like many of the other straighteners on this list, it has multiple heat settings (four to be exact!) and gets up to 440 degrees, which is great for those with thicker hair that want sleek strands in a flash.

One note we had on this straightener is that it doesn't glide as well as the others on this list. We noticed a bit more tugging and pulling, which knocked it down a few points in our book.

Best Straightener For Preventing Damage

Chi Lava Ceramic Hairstyling Iron

Beauty Experts Tested Dozens Of Hair Straighteners—These 7 Came Out On Top (34)

Pros
  • Beauty Experts Tested Dozens Of Hair Straighteners—These 7 Came Out On Top (35)Prevents frizz
  • Beauty Experts Tested Dozens Of Hair Straighteners—These 7 Came Out On Top (36)Heat can be manually adjusted
  • Beauty Experts Tested Dozens Of Hair Straighteners—These 7 Came Out On Top (37)Doesn't damage the hair, as it uses lower heat settings
Cons
  • Beauty Experts Tested Dozens Of Hair Straighteners—These 7 Came Out On Top (38)Takes longer to style due to the lower heat setting

With a focus on healthy heat, this volcanic lava-infused straightener provides consistent heat that enables you to style at a lower temperature than you would otherwise, which, in turn, helps prevent damage. Volcanic lava also produces ions that leave hair shiny and silky, while the brand’s signature Chi Ceramic prevents frizz.

"As much as I love wearing my hair straight every now and then, I’m also very afraid of heat damage, so the best feature about this tool for me is that it doesn’t only have one or two set temperatures," says Jackson. She adds that this straightener has heat settings that can be manually adjusted in ten degree increments. This is awesome when you're trying to find a temperature high enough to straighten out any super-tight curls, but low enough that you don't have to worry about burning or damaging your hair.

Because it doesn't burn or damage your hair, you can expect a frizz-free, shiny look. However, due to the lower heat setting, it does take longer to straighten the hair.

Best Everyday Hair Straightener

Drybar The Tress Press Straightening Iron

Pros
  • Beauty Experts Tested Dozens Of Hair Straighteners—These 7 Came Out On Top (40)Has a digital screen that displays the temperature
  • Beauty Experts Tested Dozens Of Hair Straighteners—These 7 Came Out On Top (41)Has a rounded shape, which creates many different hair styles
Cons
  • Beauty Experts Tested Dozens Of Hair Straighteners—These 7 Came Out On Top (42)Paint chips easily

While having the pros at Drybar do your hair every day would be ideal, having the blowdry bar’s hot tool in your hands is the next best thing. Though it’s not cheap, it’s under $200 but features titanium plates to seal in the hair cuticle, prevent frizz, amp up shine, and infrared to heat hair from the inside out to maintain a straight style all day.

Another pro? The digital screen displays the temperature (up to 450 degrees), making it easy to use even for heat styling novices. Our tester, who straightens her hair once a week, says that this tool makes her life much easier thanks to its rounded shape, which helps create curls, waves, or straight locks in an instant. Another note: It grips the hair tight to offer max heat, but it never pulls or tugs the strands.

This iron also features a 60-minute automatic safety shut off and a two-year limited warranty, so if it ever breaks you can get a new one totally free of charge.

We did notice that the yellow paint starts to chip off with a few uses, which knocked it down a few points in our book.

Most Durable Hair Straightener

Sutra Professional IR2 Flat Iron

Beauty Experts Tested Dozens Of Hair Straighteners—These 7 Came Out On Top (43)

Pros
  • Beauty Experts Tested Dozens Of Hair Straighteners—These 7 Came Out On Top (44)Heats up super quickly
  • Beauty Experts Tested Dozens Of Hair Straighteners—These 7 Came Out On Top (45)Plates are smooth against the hair
  • Beauty Experts Tested Dozens Of Hair Straighteners—These 7 Came Out On Top (46)Cord feels super durable
Cons
  • Beauty Experts Tested Dozens Of Hair Straighteners—These 7 Came Out On Top (47)Default heat is 450 degrees, which isn't great for fine, thin hair

Our tester, WH lifestyle & commerce editor Jasmine Gomez, says that there are a few things she loves about the Sutra flatiron: it heats up very quickly, its plates are smooth against the hair delivering a ton of shine, and it’s amazing at curling hair. She adds that because the straightener's plates are curved, you can achieve any style you want and add some extra bounce to your look, too.

Gomez also says that she loves that the cord feels super heavy duty. "It makes the product feel like it’ll last me for years and years." And, speaking of lasting forever, it's also made with titanium plates that lock in heat and are meant to stand the test of time.

Our qualm with this straightener is that, when turned on, it defaults to 450 degrees (this is the highest heat the iron offers). So, if you have fine, thin hair, be aware that you need to lower the heat before use.
