Here at the Strategist, we like to think of ourselves as crazy (in the good way) about the stuff we buy (like pillows), 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 (that’s four-to-five-star reviews and lots of ‘em) products and single out the most convincing. While we’ve written about the best curling irons, hair dryers, and even a certain curling iron used on the Victoria’s Secret Angels, here, we’re going deep on the best flat irons and hair straighteners on Amazon. (Note that reviews have been edited for length and clarity.)
“Infrared is so beneficial being that the wavelengths are longer and can penetrate deeper into the cuticle heating the hair from the inside out, keeping your hair's own natural moisture, leaving the hair smooth (and) shiny and keeping it extremely healthy, versus other conventional styling tools that actually pull moisture out of the hair, leaving the hair dry, brittle, dull and damaged,” said hair expert and stylist Gina Rivera.
If you have very thick, curly, or coarse hair, you may be wondering if xtava’s Infrared Flat Iron for hair can handle the job of hair straightening your locks - and we have good news for you. Our hair straightening iron has two key characteristics that equip it for the job: high, consistent, and even heat that can lock in your style and extra-wide, 2” floating plates that can handle a lot of volume.
Now that you know what the Xtava Pro is capable of, it's worth running through the features that make those results possible. Along with the solid ceramic plates for even heating, there are 10 temperature settings to choose from for optimal styling control. The temperatures are shown on an easy to read digital display and range from 265 degrees to 445 degrees Fahrenheit.

We loved the Bio Ionic’s user-friendly design. Two of our favorite features are its bright digital temperature control and the instructions stamped directly onto the tool. It also feels natural in the hand, and its matte finish provides a slight grippiness, but doesn’t pull at the hair when styling. Plus, the tool sports a uniquely shaped plate that’s curved at the tip and makes it really easy to get close to the scalp. One tester who is new to using flat irons said the Bio Ionic felt intuitive and even encouraged her to try harder styles, like creating curls and waves.
This flat iron is amazing! I have natural curly hair, and I live where it's humid a good majority of the year. This flat iron is good enough to keep my hair straight for a few days. That's with using products like hairspray, dry shampoo etc. I've been using this for about a month, 3-4 days a week, and haven't noticed any heat damage. That's always a plus. I'd say this was a good buy!
If you’re looking for an affordable mid-grade hair straightener that offers tremendous value, you can’t go wrong with the HSI Professional Digital Ceramic Flat Iron with Tourmaline. With a quick heat-up, digital LCD temperature control, and solid ceramic plates infused with tourmaline, you can straighten type 3 hair – and some type 4 hair – with ease.
As one of the hottest hair straighteners we have reviewed (temperature-wise…although it is pretty to look at, we have to admit…), the Solano Sleek Heat 450 Professional Flat Iron can reach temperatures of up to 450° F in as little as 60 seconds! This Solano hair straightener also features thin 1 inch plates, making it an ideal choice for anyone with short or medium length hair and the quick heat time ensures that even the most stubborn of curls can be tackled with a little extra heat. If you are looking or something a little larger though, it is also available with 1.54-inch plates too.
Unlike the Bio Ionic’s handy digital temperature control, the Chi Air uses a small dial on the side of the tool that’s harder to read. The dial’s placement makes it not only more difficult to get an accurate reading, but also more prone to being hit by your hand and switching to a new temperature. That being said, most of our testers didn’t mind this minor inconvenience since they don’t expect to change the tool’s temperature often.

Cleaning your flat iron is critical to ensuring it works as well as it did the first time you used it. Over time, hair product can build up on the plates. This buildup can lead to inconsistent styling results and major snagging. To clean your flat iron, simply wait for it to cool down and wipe the plates with a cotton swab or soft cloth coated in rubbing alcohol.
“This is a badass flat iron. Here’s the skinny: The moment you turn it on, it has a ‘Fragile, Damaged, Healthy’ setting, and it also auto-locks the buttons to keep what temperature you want while doing your hair. It comes with a professional bag for traveling with it. This flat iron is ‘pinky in the air while drinking your tea’ fancy. It is the Ferrari of flat irons, for a girl on a budget wanting a new flat iron. And for my fellow sistas: It works amazingly on African-American hair.”
Flat irons come in a variety of materials, but some of the most popular include ceramic and titanium. JCPenney also carries a few flat irons made with tourmaline, a rare metal that is typically found in salon-quality flat irons. Some brands even have very large plates that can straighten quite a lot of hair in one movement. At JCPenney, you can also find options that come in smaller sizes to focus on styling and textured curling, as well as irons with curved plates. In addition, JCPenney shoppers can find flat irons with digital or analog capabilities. Many of JCPenney's products are manufactured with ionic technology, which helps reduce frizz and adds moisture. Whether you're shopping for a heavy-duty flat iron or a travel iron for a trip, be sure to make the most of your budget by shopping at JCPenney.
Before placing your entire head under unnecessary heat conditions, try straightening a small section of your hair with what you believe is your ideal heat setting. Take notice of the way your hair reacts to this temperature, paying close attention to any fraying or singeing that may result. Smoking and that dreaded burnt hair smell are a sign that you may need to tone it down a bit to avoid permanent damage to your precious locks.
This durable KIPOZI flat iron can be set anywhere between 170 and 450 degrees to suit any kind of thickness or texture, and its curved plate design makes it great for giving your hair some texture. The Nano-Titanium plates heat up quickly and lock in moisture, so hair looks hydrated, healthy, and sleek. It’s also got a compatible voltage for anywhere in the world.
I ABSOLUTELY LOVE this hair straightener/curler. I was looking into buying the new TYME Iron that came out but found this one that was so similar and more than half the price. After seeing some reviews, I trusted it enough to purchase it. Got it in today and curled my hair (WITH my clip-on hair extensions) and it not only curls/straightens SO pretty but leaves hair nice and soft and silky AND therefore made my extensions blend in so so seamlessly. If you're looking for a new straightener/curler, I absolutely recommend!

Sure, the drugstore flat iron you used on its highest setting back in the day was clunky and had a tendency to fry your hair if you glanced away for more than a second, and okay fine, your mom probably told you that you looked a little “emo” from time to time. Luckily, those days are long gone and hair straighteners have truly come a long way since the days of The Jersey Shore.

When you feel like it’s time for straight, shiny locks, we’ve got your back. Our flat irons are so well-designed and powerful they can straighten even the curliest of hair. Our selection of hair straighteners also come in a variety of sizes, colors and shapes, and some even include thermal bags or travel containers so the flat iron is protected. Many of our irons also include a warranty to guarantee that the electronic components are functional for years to come. Depending on how long or short your hair is, or the type of styles you seek, you will need to select a style that best suits your styling needs. For instance, a 1.5-inch iron works best on medium to long hair, while 1-inch irons are typically made for shorter hair.
If you travel abroad often, you won't have to worry about ruining your investment, either, because the GHD Gold has universal voltage. It also features a generously long 9-foot cord with 360-degree rotation to prevent tangling. The automatic sleep mode shuts off the straightener if it hasn't been used in 30 minutes, so you'll have peace of mind if you forget to shut it off in your morning rush out the door. If something does go wrong, the GHD Gold comes with a 2-year manufacturer's warranty.
I've owned a Conair, Chi, and I-Tech straighter before, but this one is FABULOUS! A lot of research was done before I made the decision to purchase this one, and I feel like it paid off; my previous straightener was 4 years old, so it was about time. I received this new one today before I got home for my lunch break, so I had to go ahead and bust it in ;) There really is no tugging at all on your hair - so smooth, and I was shocked that it truly heats up in 15 seconds, as advertised! It also does something magical to my hair, like it adds more shine like no flat iron has done before. Mind you, my hair is very difficult to deal with. I am a Caucasian, but my hair has always been coarse, wavy, dry and thick! This iron worked beautifully on my hair. 10/10 would recommend! If it doesn't work the same after a few months, I'll be sure to update my review. As of today, I'm very happy! :)
Nearly 21,000 people gave this flat iron a five-star review on Amazon. If they factored price into that rating, then I agree. For less than $60 it’s pretty spectacular, but it doesn’t beat the fancier ones in terms of performance. The temperature automatically drops after 15 minutes of use. And while it’s easy to adjust that, it is also slightly inconvenient.
