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.
Ceramic and electrical straighteners were introduced later, allowing adjustment of heat settings and straightener size. A ceramic hair straightener brush was patented in 2013.[6] Sharon Rabi released the first straightening brush in 2015 under the DAFNI brand name. The ceramic straightening brush has a larger surface area than a traditional flat iron.
Our two testers with kinky and thick hair loved the Chi Air Expert Classic Tourmaline Ceramic Flat Iron. In fact, it was each of their top picks, with the Bio Ionic coming in second. The Chi Air reaches 410 degrees F, which is definitely hot enough for thicker and curlier hair types. The speed at which the tool worked was surprising considering the kinkiness and thickness of both testers’ hair. One tester with long, curly hair had to leave early for an event and needed to finish styling. The Chi Air moved through her hair quickly, giving her time to spare. And, even at 410 degrees, our testers didn’t feel like their hair was being fried or that the heat burned their heads. In fact, they complimented how soft it made their hair feel and how comfortable it was to use, unlike the NuMe Megastar which snagged a lot or the HSI Professional Glider which felt hot against their scalps. As one tester said, “Chi is killing it.”
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!
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.
The Babyliss gets hot quickly and moves through hair fast. This is thanks to its thin, lightweight design and the fact that it stays consistently hot. Our testers were amazed that it passed through their hair so quickly and left it smooth without feeling damaged or fried. Plus, when being styled by someone else, our testers said it didn’t snag their hair.
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!
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.
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!
Working in sections, curl your hair. Using just the wand (and not the clamp at the bottom of the wand that "holds" the hair as it curls), wrap your section of hair around the barrel. Be sure not to overlap your hair, as this will reduce heat and result in limp sections. Use your fingers to hold the edge of the section of hair close to the barrel without burning your hair. Doing this rather than using the clamp will prevent crimps in the curls.

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.


Size matters. With plates too big or too small, you’ll have to make multiple passes. This exposes your hair to high heat longer and increases the risk that you’ll do damage. According to Janine Jarman, owner and operator of acclaimed Hollywood salon Hairroin, a 1-inch-wide plate will do for most people, and if you want to use your iron for anything other than straightening, like creating curls or waves, you’ll need a 1-inch plate; anything larger won’t make the waves or curls tight enough. She also pointed out length is important too. “You need plates to be at least 3 inches long, or close to it, so you’re not spending a ton of time with small sections.”

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.”
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.

When you apply heat to your hair, which is not a living thing, you’re essentially cooking it. And, just like food, it’s easy to overdo it. Short of actually searing your hair, you still run the risk of drying out each strand, which can lead to breakage and split ends over time. Every head of hair is different, and each type of hair has an optimal flat-iron temperature. Some locks need extremely high temperatures to relax — coarse hair or those with kinky hair need 380 degrees F or above. Others need hardly any heat at all — fine or damaged hair should be good below 300 degrees.
It becomes extremely hot – up to 392 degrees Fahrenheit, and it holds that heat until you shut it off. Because of this, you can straighten any type of hair with Chi, including very thick and coarse tresses. So if you have such hair, this iron could be your best option. It is not only designed to straighten but also to curl hair. Thanks to its ergonomic design, you won’t strain the hands and wrists during use.
If Gisele's mane meets your #hairgoals, consider this iron created by her stylist Harry Josh. The wider-than-usual 1.25 inch plates allow contact with a larger surface area in order to speed up styling time, and the quick-heating ceramic-titanium plates (it takes only 45 seconds to reach 400 degrees) abolish frizz and boost shine for model-worthy strands.
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 your hair is plagued by tangles and knots on a regular basis (even in between straightening!), try switching your hairbrush out for a wide-toothed comb! The added space in between the teeth gently separately knots and tangles without the painful “Ouch!” with each stroke. If that still isn’t enough to tame your stubborn tresses, try a wet brush! These brushes are specially designed to work through knotted, wet hair without any tugging or pulling.
