Most of the hair straighteners we reviewed heat up in under a minute, but the Cloud Nine Original Flat Iron has to be one of the fastest on the market! In as little as 20 seconds, this hair straightener transforms from cool to hot, hot, hot! With this model, there is no need to wait around for your hair straightener to warm up, which means you spend less time getting ready in the morning and more time getting on with your day.
While you might think that a hair iron is only necessary to straighten curly hair, a hair iron is actually a great tool for styling straight hair. A flat ceramic flat iron can help smooth away flyaways and a add sleek shine to your hair. You can also use a flat iron to shape straight hair, and you can use it near your scalp to add volume to limp hair.
The two strips of silicone atop Bio Ionic’s flat iron plates seem silly, but they serve an important purpose. By buffering the outer edge of the plates, they reduce your chances of hair snags. They also force you to glide the flat iron more slowly through your hair (they are called speed strips, after all). While the slower technique maximizes shininess and smoothness, the speed strips can become a bit of an obstacle if your hair is thick.
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!
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.

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!
Unlike the plain Jane ceramic plates of most hair straighteners, the tourmaline-infused ceramic plates in the CHI Air Expert Classic Tourmaline Ceramic Flat Iron are designed to keep your hair healthy during styling. Specifically, the tourmaline helps to more evenly distribute the heat during use which, in turn, creates a higher number of negative ions for shinier and healthier looking hair with each use. This reduces the static electricity created, meaning you get a sleeker, smoother style.
Ever since the early 2000’s when the planet collectively decided that straightening our hair to death was a good idea, beauty companies have been searching for a way to achieve beautiful and natural-looking straight looks without frying or unnecessary damage. From ceramic plates to protective sprays and everything in between, we have been desperately searching for some way, any way, to show off a straight head of hair that isn’t entirely made of straw.

For some people, automatic shutoff is a critical feature since forgetting to unplug your flat iron could lead to a fire. However, others aren’t fans of auto shutoff since that means their flat irons could turn off while they’re still styling their hair. If this is the case for you, we recommend investing in a timed switch. That way, you can program the switch to turn off at a specific time and your flat iron will shut off as well.
As an added bonus, titanium has also been found to resist rust, so your hair straightener will keep its out-of-the-box look for years to come. This is particularly important when you are making a long-term investment by purchasing a high-end or professional hair straightener. After all, you wouldn’t want your car or bathtub to start rusting after just a couple of uses and the beauty tools you use for your flowing hair should be no different!
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!
Thankfully, we’ve learned a lot about hair care and preserving your hair’s natural integrity while styling. However, this wasn’t always the case. If you ever had a perm done in the 80’s or teased your hair to holy heaven in the 90’s, chances are pretty good that your hair has endured a bit of damage. The same can be said if you color your hair on a regular basis or recently went from your natural brunette color to a bright platinum blonde. No matter how the damage was caused, there are certain features you will want to shop for when selecting the ideal hair straightener for your course hair type:
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.
When putting your hair under the intense heat of a flat iron or hair straightener, you’ll probably find that breakage and damage are that much more common. And that’s why we absolutely love the LumaBella Keratin Duel Touch Hair Straightener! Packed with all sort of high-tech features and gizmos, LumaBella’s hair straightener achieves salon-worthy results without the harsh damage of most styling devices for a natural, healthy shine with each use!
