The HSI 1st Gen Professional Ceramic Flat Iron is designed with tourmaline-infused ceramic plates, generating negative ions and allowing smaller water molecules to penetrate into the hair shaft to reduce frizz and static. Built for durability and lasting results, the floating plates give the flexibility to flip, curl or straighten your hair – all with a single iron.
At $230, the Bio Ionic is pricier than any of our top picks. But you get what you pay for. You can truly do with your hair whatever you desire — straight or curled — in one pass. And, if you’re worried about it breaking a few years after purchase, the Bio Ionic comes with a five-year warranty. By investing in a better-quality tool up front, you won’t have to replace your flat iron every couple of years. Plus, the Bio Ionic goes on sale every now and then, so it’s worth keeping your eye out for deals.
The more temperature control options you have, the more control you'll have over the heat you'll be applying to your hair. Keep in mind, any type of heat styling can be damaging to your strands, so you want to take care not to use too much high heat, especially if you're styling daily. Flat irons that have lower temperature options that start around 250 degrees Fahrenheit are ideal for those with thin, damage-prone hair. If you do have thick hair, higher heat settings can help straighten those curls. To help prevent damage, you should start with lower heat first, and then only increase as needed. Keep in mind, anything above 400 degrees has the potential to damage your hair. Even those with coarse, curly hair should stay within the 350-400 degree range to be safe.
Nor does it speak to those of us who work long hours at our job - who support our families and who struggle with issues like how to pay the bills or how to put the kids through college - who have limited time and energy for training - and who are more interested in how to train for lifelong strength and health than in how to gain 30 pounds of muscle in six weeks.
Features like this prove that hair straighteners really have come a long way over the last decade, and the LumaBella Keratin Duel Touch Hair Straightener certainly doesn’t disappoint in this regard! When the terror of hair damage is removed from everyday straightening, there’s no limit to the styles you can create with a hair straightener like this making this an ideal choice for novice and expert stylists alike!
While temperature control is typically a good thing to have in a hair straightener, it can also result in hair damage if you're keeping the temperature too high. The GHD Gold eliminates the chance of any user error, operating at an even 365 degrees Fahrenheit. This is the optimal temperature for most hair types, getting you smooth results without damaging your hair. The gold coated ceramic plates heat up quickly and maintain an even temperature, eliminating the chance for any hair damaging hot spots as well.

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 floating plates are contoured with smooth edges, so you won't have to worry about your hair snagging as you're styling. If you have thicker hair, you may want to consider the 2-inch plate option, which will cover more surface area and help you style your hair more quickly. However, if you'd rather have the versatility of being able to curl and flip your hair as well as straighten it, we'd recommend the classic 1-inch plate.
Negative ions have been a longtime fan favorite in the hair care industry, and it is no surprise that this same technology would appear in our top picks for the best hair straightener. Negative ions have been found to reduce static and frizz while locking in moisture, and the same goes for your hair when you use the CHI Air Expert Classic Tourmaline Ceramic Flat Iron!
For better or worse, we are B-U-S-Y nowadays. Running from meeting to meeting and trying to pick up our kids from carpool before soccer practice, it’s no wonder that we often place ourselves at the bottom of our daily priority list. This mindset typically carries over into our appearances and explains why more women than ever are rocking messy top knots and buns than ever before.
The titanium plates in the BaByliss Pro Nano Titanium Straightening Iron were designed to conduct high levels of heat (again, up to 450° F!) in a short amount of time. Coupled with the Nanotechnology that is packed in each plate, this hair straightener is ideal for anyone that experiences unwanted frizz or static on a regular basis! The titanium also acts as a barrier from corrosion keeping your hair straightener and precious strands free of build-up for years to come!
This BaBylissPRO porcelain ceramic straightening iron is made with porcelain ceramic, which distributes far-infrared heat evenly across the strands. Not only is it gentler and more healthy for your hair, but it can handle wide sections of hair at once because of its long barrel. The shape is rounded and sleek, so it’s ideal for curling, and it won’t catch or knot while you’re curling.
Though it looks high tech with an LCD screen, this budget-friendly straightener has impressed Amazon reviewers everywhere. "I have very thick curly/wavy hair and in a matter of 45 minutes my hair was the straightest I’ve ever been able to get it by doing my hair on my own," wrote one reviewer from Florida, who said her straight hair managed to endure the state's humid climate.

“I’ve owned a Conair, Chi, and I-Tech straighter before, but this one is FABULOUS! 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: It adds more shine like no flat iron has done before. Mind you, my hair is very difficult to deal with. It has always been coarse, wavy, dry, and thick! This iron worked beautifully on my hair.”
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.”
According to Jarman, you should never have to use both hands to clamp the iron down on your hair. You not only risk burning your fingers on the plate end, but this can pull at your hair and break it. High-quality, modern irons are designed to clamp together from the handle end only, so if you find that your iron requires pressure on both ends, it’s time to upgrade.
If you have trouble remembering to unplug your flat iron before heading out, you’ll appreciate the Chi Air’s one-hour automatic shutoff. Since people have preferences regarding auto shutoff this wasn’t a criteria for us, but our testers thought it was helpful. One tester said she often leaves her flat iron on in the morning and invested in a timed switch to make sure it’s off. So if you’re forgetful when it comes to turning off your tools, then auto shutoff might be an important feature for you.

The digital interface accurately displays the fully adjustable temperature setting from 170 degrees to 450 degrees Fahrenheit, providing optimal performance for any hair type. The floating plates with curved edges continuously adjust the tension and angle of the plates to avoid snagging your hair so that you have full flexibility when creating sleek, wavy or curly styles.
Those with fine hair can keep the straightener at a lower temperature, while those with thick hair can increase the temperature to ensure they'll walk away with the same smooth results. No matter your hair type, the floating plate design and the curved edges of the plates themselves prevent any snagging or damage so your hair will glide through smoothly.
Ask any seasoned hair stylist for a flat iron recommendation, and you will hear the same brand time and time again: CHI. Known the world over as a leader in hair care and styling, CHI is your go-to name for salon results at home. While CHI offers a variety of designs (and fun colors!) to choose from, the brand’s G2 Ceramic and Titanium model is what caught our eye when researching the best hair straightener. This hair straightener is packed with high-tech features and an upgraded, ergonomic design for the shiniest and straightest do’ you’ve ever seen!

If you’ve ever used a CHI hair straightener before, then you’re probably pretty well acquainted with the turn dial temperature control of models’ past. While this dial design made it easy to switch on your hair straightener each morning (even before you have had your morning coffee!), it also made it all too easy to accidentally change the temperature during use.

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.)


Just because you were blessed with a head of naturally straight hair, doesn’t mean hair straighteners aren’t for you! Hair straighteners are a great way to style the split ends that are all too common with straight hair types and can also give your hair a natural-looking curve for added volume! When shopping for the best hair straightener for your naturally straight hair, you will want to look for the following:

Derek Yuen, the man responsible for Cole Sprouse's grown-up new look, recommends the GHD Platinum Professional Performance iron. The flat iron is consistently and evenly heated at 365 degrees, which is safer and less damaging on the strands. “The beveled edges also allow for infinite styling possibilities, not just just for straightening hair,” says Yeun.
If you are interested in adding the benefits of keratin use into other aspects of your hair care routine, treat yourself to a keratin-rich hair mask once per week! There are dozens of fantastic keratin masks on the market to choose from (and even in your local drugstore!), but we love Naat’s Brazilian Keratin Intensive Hair Mask (which you can buy here from Amazon) for a consistent shine every time!
