With well over 25,000 reviews, the HSI Professional Ceramic Tourmaline Ionic Flat Iron is one of the best straightening irons you can get, but because of its thin build and rounded plates, you can also use it to curl your hair. It’s got solid ceramic plates to reduce damage, evenly heat hair, and promote shine, and if you’re a traveler, it’s got a dual voltage that can be used anywhere in the world.
A lot of people don’t know there are tons of ways you can style your hair with a flat iron, and this actually might help you decide what size iron to get. You can curl, wave, straighten, add body, twist and more – just with a flat iron! Your straightener is so versatile you can skip most other styling tools and save money by investing in one that will do all of this for you. I walk you through different options for styling with your flat iron so you get the hairdo you want.
Many hair straighteners feature a visual interface to alert you when the device is getting a bit too hot for comfort or when it has surpassed the ideal temperature for your hair. With the T3 Micro Single Pass Flat Iron, you can expect the same visual cues with the bonus of sound alerts as well! That’s right; this flat iron will actually tell you when it reaches its ideal temperature or when it is about to shut off automatically after one hour. Now that’s some hot tech!
The glider plus is designed to protect your hair with integrated heat balance micro processors that continuously monitor the exact temperature across the surface of the plates and automatically adjust the temperature for evenly distributed heat. That means fewer passes are needed for silky results, while protecting your precious hair from over heat exposure.

There are a few downsides to the BaBylissPro Mini. For those with longer hair, it may take a little more time to straighten than it would with a normal-sized straightener. It also lacks the 360-degree swivel cord and automatic shut-off found in most full-size hair straighteners. However, these downsides can be overlooked when taking the other features into consideration, like its lightweight, compact size and the fact that it can still hold the same temperatures as a full-sized hair straightener.
The GHD brand is a favorite among celebrity hair stylists because of its reliability and shiny, frizz-free results. Just because you aren't setting foot on the red carpet anytime soon doesn't mean that you can't have celebrity quality hair. The GHD Gold professional makes it possible for you to achieve shiny and frizz free results at home, so you can feel red carpet ready even if you're just grabbing coffee with friends.
One of the Babyliss’ major drawbacks, and why we only recommend this flat iron for experienced users, is the outside gets hotter than any of our other picks. Hot to the point that it was too hot to hold. One tester said she was “afraid to accidentally touch the top of it.” Others said they could feel the heat against their scalps. At first, another tester said she didn’t mind the heat. This was moments before she burned the top of her hand when it merely grazed the side of the tool.
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.
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.

If you want to achieve sleek, pin-straight hair, a high-quality hair straightener should be in your beauty arsenal. A hair straightener, also known as a flat iron, smooths the follicle of your hair between two heated plates. Some hair straighteners can even do double duty, creating loose waves and curls without the frizz. So how to choose the best hair straightener for you, and get those shampoo commercial-worthy locks? There are several things to consider to make sure you'll get the best style result, but the most important is hair type.


This feature is particularly helpful if you have textured hair with waves or curls, which can become damaged so easily by heated styling tools. That said, it is not clear which heat setting is ideal for users with thick or somewhat straight hair. This may make this slightly more difficult if you are using a flat iron for curling purposes or if you need to straighten an especially thick head of hair each day! However, we are confident that a little tinkering is all it takes to find the perfect heat setting for these different hair types and styles, so you can rest assured that this hair straightener can still meet all your hair styling needs!

An upgrade from their since discontinued Eclipse Styler, you won't be tempted to heat this flatiron up to 450 degrees, because the temperature dial is always stuck on one number: 365 (the ideal heat to mold hair without frying it, according to the scientists at GHD). Underneath each of those 365-degree plates are three fancy sensors that measure the density of the hair in the iron so that it can maintain consistent heat regardless of the chunk of hair you grab. The result? Silky, shiny hair with zero frizz.
