Here at the Strategist, we like to think of ourselves as crazy (in the good way) about the stuff we buy, but as much as we’d like to, we can’t try everything. Which is why we have People’s Choice, in which we find the best-reviewed products and single out the most convincing ones. (You can learn more about our rating system and how we pick each item here.)
And while we’ve written about hair tools before — including the best brushes, blow dryers, and curling irons — here, we’ve rounded up the best hair straighteners, as praised by the most enthusiastic reviewers on Amazon. We are prioritizing full-size flat irons straighteners, but there are lots of even less expensive mini hair straighteners on Amazon too.
Best-rated flat iron
“They’ve done it. They’ve made a flat iron that can control the beast(my hair),” writes one impressed reviewer. And more than 19,000 reviewers give this flat iron five stars, many of whom give it similar praise. “I can literally do ONE pass, and I’m done,” one reviewer reports, and thousands of others say this hair straightener works wonders on their curly hair. “It heats up very quickly and gets hot enough to straighten my curly hair while leaving it soft and shiny,” one writes, while another with natural hair says, “It turned my hair straight to silk and it lasted a while.” One user says it’s sturdy, too: “I’ve had mine for about three years now and is just as durable and works just as well as the day I bought it.
Best-rated (less expensive) flat iron
With over 4,000 five-star reviews, this hair straightener from Remington is described as “easy to use” at a “great price.” “I bought this as a cheap replacement for a high-end CHI and this is just as good,” writes one reviewer, adding, “The buttons are in the right place, and it heats up quickly.” In addition to its quick-heating ability, many commenters agree that this flat iron lives up to its anti-static name: “It heats up fast and has a wide range of heat settings. The temperature lock is a great feature that many other flat irons don’t have. With the lock on you’ll always have a consistent temperature without risk of scorching your hair because you accidentally turned the heat up. The iron is super smooth and with the anti-static feature you don’t have to worry about frizzies or fly aways. It has a nice long swivel cord that doesn’t get twisted up or tangled. This is a great iron at a very affordable price!”
Best flat iron for thick hair
This hair straightener from BaBylissPRO has a wide base of adoring fans who think it’s well worth the price tag for its ability to work through their thick locks. One says, “I have used the CHI brand over 10 years and loved it. Decided to buy a larger iron and went with this one based on the reviews. WOW, so, normally it takes me 20 minutes to straighten my hair with the CHI, not anymore, I only spent 5 minutes for my long thick hair, and no frizz and lasted for days with minor touch up.” Another reviewer with “unusually thick hair” said that it “ turned my straightening routine into less than ten minutes, when it used to take over a half hour.”
Another particularly happy customer wrote a short, 600-word essay on her love of this product, calling it, “a legit game changer. The silkiness, the smoothness: I felt like Beyoncé, circa ‘Crazy in Love.’ Any-who, this is joy, and I love this inanimate object. That is all, make the right choice.”
Best flat iron for fine hair
Thanks to the tourmaline ceramic plates, this iron “glides through my hair, never grabbing or pulling it,” writes one reviewer. Others point out that this tourmaline ceramic plate “works way better on fine hair than other types,” not burning thin strands even at high temperatures. Or, as one reviewer writes, “It’s well made, it doesn’t snag my fine hair and because of the heat control settings, doesn’t burn it either. Yay for not having breakage!”
Best flat iron for wet hair
Reviewers pick this straightener when they want to be able to straighten damp, or even wet, hair, and according to nearly 1,500 five-star reviewers, it works. One impressed user describe this flat iron’s ability to steam wet hair into dry as “basically black magic.” Another says, “When they say you can dry wet/very damp hair with the flat iron instead of blow drying first, they mean it! I wrap my my hair in a towel for maybe 20 minutes, add leave-in conditioner (gotta take care of the permed and highlighted hair, you know) comb it, section it and start flat ironing. In 15 minutes I have completely dry and straight hair. And when it poured rain the next day, my hair did not frizz or get wavy, it stayed straight!” However, several reviewers warn that you should turn the steam vents away from your head during use: “You always have to hold it with the steam vents facing away from your head, otherwise the steam vents into your hair and could potentially burn you.”
Best volumizing flat iron
Lots of comments leave photographs of their voluminous hairdos in their reviews, as proof of this flat iron’s hair-raising power. This ringing endorsement more or less sums up Voloom’s appeal: “I really think that the inventor of this miracle tool should be made a saint, or have a town square named after them. If you have to sell your first born to purchase this device, do it.”
It’s been life changing for folks with thin strands too, like one who says, “I hate my hair. Hate it. I have PCOS so it’s thin (as in, you can clearly see at the top of my head), it’s flat, and it doesn’t hold a curl. It’s a constant source of anxiety for me. Who doesn’t want thick luxurious hair?” She continues, “This is such a game changer for me. Yes it was expensive … but for now I am thankful because for once I feel a little more confident about my hair.”
Best flat iron for straightening and curling hair
This flat iron gets its two-in-one name from its ability to curl and straighten hair. One reviewer who loves its rounded design says, “I’m not very good at curling my hair with a straightener and this just made me a PRO.” They call the process, “So simple. And left no weird crimp spots that I normally had. Gives it more of a combo curling iron type use, with the smoothness of a straightener.” Another reviewer, who loves beachy waves, says, “I normally have to straighten and then mess around with a curling iron to get those waves,” but they achieved the same look with this tool “in just a couple minutes. I wanted to try strictly straightening my hair too, just to see how well it worked for that too, and it was slick.” The flat iron also comes with a number of accessories that reviewers appreciate. “The clips that came with it made it so easy to hold the extra hair up and out of the way,” one says, adding, “The comb it came with made it easy to separate the hair with the handle and smooth hair by combing before using the curling iron.”
Best flat iron with temperature control
Reviewers love that they can adjust the temperature on this flat iron, and that versatility is why hairstylist Benjamin Muller told us that this straightener makes it “easy to transition for hair type and texture.” Another user explains, “On the box it states what temperatures for your type of hair, and obviously I have been using temperatures way over what my hair should use and why it has damage.” Once you find the right temperature however, another user notes that it’s “Easy to set the temperature and [the] knob is placed in a good spot where I don’t accidentally turn it up or down while in use.” Reviewers also appreciate that this straightener doesn’t snag their hair, which at least one reviewer thinks makes this a safer option. As one explains, “It also doesn’t pull on the hair so much, so that helps prevent breakage.”
Best infrared flat iron
This iron “heats the hair from the inside out, using infrared heat, so no burning of hair of cuticle, just like advertised! No smoking either,” explains one reviewer, saying, “This flat iron is, by far, the best I’ve ever owned (and I’ve had ones I spent over $120 for that I have given away). I’ve already sung its praises to everyone I know who uses one. I cannot recommend this straightener enough for anyone with with kinky curly hair who wants straight, shiny, soft and manageable hair. It truly earned its 5 star rating.”
The infrared technology is also a time saver, as one user says, “Normally it takes me 45-50 minutes to straighten my hair with my old ceramic iron and it took me about 25-35 minutes to straighten with the Xtava iron. My hair was straight with one swipe of the iron and it left it shiny, soft, and without frayed ends.”
Best pearl ceramic flat iron
This tool’s unique feature is its real pearl-infused plates, which one reviewer says leave her hair “shiny and smooth. It doesn’t snag/grab pieces tiny strands of hair like some lower-end irons I’ve used. It is professional quality, no doubt.” Another compares it to pricey professional products, saying, “With frizzy hair, flat irons are a part of life. I’ve had tons of irons and even spent well over a hundred on a single professional iron my stylists have sworn by and this is the best I have ever come across, period … I had to go and buy everyone in my family one since I love it so much! Even bought an extra one to keep at my desk at work in case I ever need a quick fix.”
Best travel flat iron
This travel-size pick is so high functioning that many reviewers turn to it for everyday styling as well. “I bought this for an overseas trip, but I’ve continued using it at home. I greatly prefer it to my full-size flat iron,” writes one reviewer. “I have a chin-length bob, and this is perfect for adding some texture/wave to my hair.”
It’s the “perfect size to throw in your purse on the go,” says one reviewer. Another, who found the smaller size to be life changing, writes, “Being that I’m a mother, a wife, and someone with a full-time job, I am constantly on the go. I don’t always have the time to smooth my crazy hair straight before leaving the house. I had a hairdresser inform me that my hair type was naturally frizzy, and I live in the humid state of Alabama to top it off. There is nothing more frustrating than spending ALL that time flat ironing my hair straight JUST for it to turn into a frizzy tangled mess as soon as I leave the house. It is AMAZING to be able to take my hair straightener wherever I go! This product has COMPLETELY boosted my self esteem and I don’t walk around feeling self conscious about my hair.”
Best travel flat iron with storage bag
“This straightener is shockingly tiny when you first look at it,” writes one purchaser, but they’re just one of many reviewers who say that it’s up to the task of straightening a full head of hair despite its size. They do note, it “did not take much longer than a full-size straightener to do the job.” But the combination of powerful function and dual-voltage wiring in a compact package makes Lovani’s portable flat iron very popular with travelers. “It’s small enough where I don’t feel guilty about packing it with little space to spare,” writes one traveler who “did not check a bag” on their nine-day trip to Europe. Many also love the included “heat-resistant bag,” which they say works well for storage and for times when they are rushing around. “LOVE that you can put it in the case while it’s still hot and you don’t have to wait for it to cool down,” one reviewer explains.
Best mini flat iron
Reviewers with short hair love this mini straightener. “This flat iron is perfect for my pixie,” writes one, explaining, “I love how hot the iron gets and how skinny the actual plates are. I can even curl the really short hair around my ears and nape area. It was hard to find a flat iron with plates this size that wasn’t $150 or more, but this is it!” However, the miniature size is also appreciated by those with fine or thin hair. “I had no idea flat irons this narrow even existed. Total game changer,” says one commenter. “I have fine, thin hair, and a pixie cut. Even if I had longer hair again, I would only use this! Very well made, heats up quickly, and no snagging or pulling your hair out. You can get really close to your roots without burning yourself.”
