I tried to break everything up on the chart by category so it’s easier to narrow things down, but you have to keep in mind there is a ton of overlap in styling tools. You can have large ceramic tourmaline and small titanium steam as well as just about a thousand other options. The point is, although my table is here for those of you who already have an idea of what you want, there is a small chance you might end up looking at something with a few extra bells and whistles because there is so much overlap. If you’re not sure what different kinds of irons there are, head over to my buying guide so you can get that all sorted out before you start reading the reviews.

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!
"Unite Pro Tools Flat Iron is an easy-to-use, low maintenance iron," says Chris Dylan. Dylan works with Kylie Jenner so finding an easy-to-use tool is a must when you’re helping someone go from a platinum blonde bob to jet black floor length extensions. in a span of a week. He notes that with a fast-heating iron and beveled edges, it creates soft waves and has a great temperature gauge that keeps you firmly in control of the heat.
Most mid-grade and high-end hair straighteners come with plates that are 1” or 1.5”. If you are looking at one that is 2”, 2.5”, or even bigger, steer clear immediately. Not only does larger plates make it easier for you to accidentally over-iron (and seriously damage) your hair, but they also make it more difficult to get all of the way down to your roots. For anyone with type 3 or type 4 hair, trying to use a large-sized flat iron would be far more trouble than it’s worth.

Speaking of stellar straighteners, here are 11 of our top picks, ya know, if you're looking to upgrade yours.

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.
GHD’s “styler” is permanently set to 365 degrees Fahrenheit, which the company says is the highest temperature hair can tolerate before it becomes damaged. As a person who went from a dark brunette to blonde highlights, I can vouch for its straightening power on processed hair. And though I don’t typically think of “comfort” as a flat iron necessity, the springy hinge that connects the two plates really did make it easier to clamp and glide the tool down my hair with minimal effort.
