We’ve all heard the saying that the grass is always greener on the other side, and our hair types tend to follow the same old adage. If you were born with a head full of beautiful curls, you probably spent your childhood longing for straight hair; if you were born with bone straight hair, then you’ve probably spent more hours than you’d care to admit with a throbbing curler-induced headache. No matter how hard we may try to love the hair we’re born with; the truth is that most of us wish there were something else perched on top of our heads from time to time.
“I bought the HSI titanium tourmaline ionic flat iron and I was so impressed with it. It glides so smoothly down the hair without any tugs! The digital display screen lets me adjust the temperature without any problems, it heats up fast, and I love that it comes with a pretty purple pouch, glove, and argan-oil serum. I also own the digital HSI ceramic ionic flat iron from 2013, and it’s still going strong, but I do like the titanium iron better, and I see myself using for it for years to come. It leaves my hair shiny and soft!”
When shopping for the best hair straightener for your unique hair type, it can be difficult to decipher all of the different styles and specs. That’s why we’ve done the hard work for you and created this all-inclusive guide to finding the best hair straightener for your unique head o’ hair, so you can spend less time scrolling through pages of products and more time rocking your new dream do’!
Eight micro-sensors with HeatBalance technology are used to evenly distribute heat, regulating the temperature so that you spend less time applying heat. As a result, it takes less time to straighten hair, preventing it from damage when styling. Additionally, the 1-inch plate width is wide enough for any hair length, yet narrow enough to style your bangs.
The type of heat you use to style your hair makes a big difference in how healthy it will be. Our Xtava Pro-Satin Infrared Ceramic Flat Iron for Hair uses infrared heating technology, which heats hair from the inside out. Infrared technology is a game-changer for styling your hair because it allows heat to penetrate directly into the inner part of the hair strand, not just the outside layer. Infrared heating to the middle of the hair strand provides a more effective heat for styling and decreases damage to the outside of your hair. Infrared technology also stimulates negative ions in your hair that draw oils from the hair shaft to the surface; this helps lock in moisture and lock in your look, even in humid weather. Better heat = better hair health. Guess that’s not much of a secret after all, is it?

The Bio Ionic worked well on all of our testers’ hair, but it’s best on drier hair with a medium thickness. We spritzed testers’ hair with some keratin smoothing treatment, but the Bio Ionic did a lot of the heavy lifting to make our hair feel softer. The tool gets hot, but not too hot to grip, and it excels at creating the silky volume you want without making your hair pin-straight and flat. One tester put it perfectly: “[The Bio Ionic] is the Rumplestiltskin of hair straighteners. It’s turning straw into gold.”

While there are so many different types of hair straighteners out there, you can rest confident in knowing that if you’re picking one of the flat irons that our experts selected, you are treating your hair (and your confidence) to the best flat iron for natural hair out there.
The Strategist is designed to surface the most useful, expert recommendations for things to buy across the vast e-commerce landscape. Some of our latest conquests include the best women’s jeans, rolling luggage, pillows for side sleepers, ultra-flattering pants, and bath towels.

“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.
Consider this the perfect flat iron for full hair. "It is great for thicker textures because it distributes heat evenly, allowing for less passes through the hair," explains stylist Lacy Redway. The plates "make it easier to straighten or curl longer hair lengths." Redway was responsible for  Tessa Thompson’s sleek ‘do on her past ELLE cover, so you know it’s top-notch.
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.)

With ceramic tourmaline technology, floating plates, and an extremely wide range of temperatures, the Berta Professional tourmaline ceramic flat iron is great for this type of job. It’s also got an elongated body so hair doesn’t slip off the end while you’re styling, and reviewers are saying things like, “I got the hair straightener to curl my hair and it does a great job. My hair never holds a curl but this flat iron did the trick.”
Creative director of GLAMSQUAD Giovanni Vaccaro prefers this flat iron by Sedu. "The ceramic plates are really key to maintain the integrity and healthiness of the hair," he says. To get expertly straight hair, Vaccaro recommends using a boar-bristle brush to help mediate frizz, and that "the follow through is key" when moving the iron and comb completely from roots to tips.
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 being limited to only a handful of temperature settings isn’t really your cup of tea, look no further than the BaByliss Pro Nano Titanium Straightening Iron!

Now that you know what the Xtava Pro is capable of, it's worth running through the features that make those results possible.

Titanium is a lightweight metal that heats up very quickly and can hold high heat at a consistent temperature. This material is ideal for those who have thick, curly, or natural hair that can be more difficult to straighten. Since it's lighter than ceramic, it also makes for a lighter hair straightener overall, which means less arm strain as you're taming your mane. As someone who has very thick hair, I can attest — Any feature that can make styling easier and faster is a plus.
It is important to consider what options are important to you when selecting a hair straightener. You must select a hair iron with a heat setting that fits your needs. If you have fine hair, a lower heat setting may be sufficient. However, thick coarse hair may require a higher heat setting to achieve your desired look. Plate size should also be considered. A flat iron with small plates might be best for shorter hair, while a flat iron with larger plates might be best for longer hair. Some hair straighteners have features such as temperature readouts and rollers that might be important to your needs.
Not sure which temperature setting is right for your hair? We recommend starting slow and building up to higher heat settings gradually. Not only will you be able to perfectly identify the optimal heat setting for your hair, but you will also avoid overheating. After all, very few of us actually need upwards of 400° F to see the salon results we’ve always wanted!
Straighteners work because they have flat plates that get hot and touch together on either side of your hair. By doing that, they put heat through your hair follicles, trap in moisture and take out frizz. The plates on a flat iron can be made of several different materials, and they’re good for different uses. The best iron for you varies depending on the type of hair you have, the type of styling you want to do, and the amount of heat your hair needs.
Heat protectants contain ingredients that coat hair and slow down heat induction. Janine Jarman says, “Blow dry your hair properly; use a heat protectant product; and with the right iron, you should not have to make a bunch of passes to get the results you want.” We used TRESemmé Expert Selection Heat Protection Spray, Keratin Smooth. Most of our testers liked how it worked on their hair and felt a noticeable difference when using it. Our tester with kinky hair didn’t use the product because she knew it wouldn’t work on her hair. Instead, she recommends using an oil (like an Argan oil) or a hair grease to add moisture to the hair, which makes it easier to straighten.
