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

HSI Professional Gilder 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

INFINITIPRO BY CONAIR Tourmaline Ceramic Flat Iron

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.”
