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.”
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.

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!
This iron is one the coolest tool I’ve ever used. It is a beautiful looking straightener with very high technology. With 50% more power and wider plates (1.5″), the T3 SinglePass X is specifically designed to straighten hard-to-manage hair, such as long, thick or coarse hair. Most importantly, it is designed to do the job fast – it straightens in a single glide!

This got my hair straight. The teeth on the Iron helped to get my ends straight. So I didn’t have to chase it with a brush/comb. It comes with a comb, 2 clips and a bottle to add the water to the dispenser. No directions on how to add the water. But I looked it up on you tube. I added a couple of drops of Argab oil to the water mixture. This gave me sheen, moisture and protection. The only thing is I couldn’t get my roots. I have really thick hair so I have to get super close to the root but I just used my other Flat Iron to catch the roots. Would still recommend and will be using this method from now on.
This Amazon reviewer dubbed it the "perfect travel tool" that straightens their hair just as effectively as a normal sized hair straightener and they like that it automatically changes voltage so you don't have to worry about doing so manually. Reviewer Lynn B. writes on Ulta that she loves how quickly it heats up, and how she can easily pack it away right after use thanks to the heat-resistant carrying case it comes with.
Crimping irons[7] or crimpers work by crimping hair in sawtooth style. The look is similar to the crimps left after taking out small braids. Crimping irons come in different sizes with different sized ridges on the paddles. Larger ridges produce larger crimps in the hair and smaller ridges produce smaller crimps. Crimped hair was very popular in the 1980s and 1990s.[citation needed]

Before explaining the advantages, let’s discuss the heating process. Flat Iron does the basic purpose of heating so that the hair follicles can flatten. Flattening of follicles is needed to create any hairstyle. Hair follicles contain natural moisture. When we heat the hair, the natural moisture gets eliminated. That’s why hair ends up with the rough texture.
The CHI brand has long been one of the most popular for hair straighteners and flat irons, and for good reason – their products work well and they work quickly. The CHI Original Pro 1” Ceramic Tourmaline Flat Iron is no different. Thanks to its durable build, quality craftsmanship, and leading tourmaline-infused ceramic plates, this is the last hair straightener that you will need to buy for a long time.
When you’re shopping around for a great flat iron that’ll give you flawless waves, you’re essentially looking for three specific qualifications. First, you want something that’s got one inch plates or smaller. Any thicker, and the curls will be so loose, they’ll be virtually non-existent on anyone whose got hair shorter than the butt. Secondly, a rounded body is a must, as you’re wrapping the hair around and through the straightener to create a loose curl. Third, you need something that’s sleek and easy to handle, so your hair won’t snag and break off while you’re curling. Check out these awesome options that make it easy to curl your hair with a straightener.
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.
In addition to a fast heat-up time and multiple temperature settings, the 9-foot cord and 360 swivel make for easier styling and prevents and tangling. You can also travel with this styling iron thanks to the dual voltage settings. Anti-slip edges and floating plates allow your hair to glide effortlessly between the plates, with no pulling or snagging which can be especially damaging for fine hair.

If you are unsure what exactly your hair type is (or if it has changed over the years, which happens more often than you’d think!), check out this incredible overview by the hair professionals at Redken! Don’t stress if you have combination hair (i.e., fine and curly or thin and straight) either; we recommend choosing a hair straightener based on your biggest hair complaint and focusing on that problem first. So, if your curls are driving your nuts, you will want to select a hair straightener with higher temperatures, thin hair needs moisture, etc. You’ll find that your entire hair type can usually benefit from the extra TLC!
No two heads of hair are the same, so the straightener that does wonders on your best friend's fine tresses may be useless on your curly mane. Luckily, there are many different types of hair straighteners. Some provide higher heat settings and wide plates to tackle thick curly hair, and others have ceramic plates and options for low heat settings that are better suited to easily damaged fine hair.
By-and-large, most people with natural hair have some variation of type 3 or type 4 – which is exactly why low-end hair straighteners can be so dangerous. More curly natural black hair has a tendency to be more porous than other hair types. As a result, it can lose moisture easily and become damaged. With the wrong flat iron, this can lead to split ends and breakage after just a single use.
If you have ever visited a luxury spa or wellness company, you have probably run across far infrared heat a time or two. Without going into too much science, infrared heat is the same heat you feel when the sun kisses your cheeks and warms your body from the inside-out. Far infrared heat, in particular, has been used by medical and wellness professionals for years to treat a variety of conditions from muscle pain to even cancer.
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.
“This is a badass flat iron. Here’s the skinny: The moment you turn it on, it has a ‘Fragile, Damaged, Healthy’ setting, and it also auto-locks the buttons to keep what temperature you want while doing your hair. It comes with a professional bag for traveling with it. This flat iron is ‘pinky in the air while drinking your tea’ fancy. It is the Ferrari of flat irons, for a girl on a budget wanting a new flat iron. And for my fellow sistas: It works amazingly on African-American hair.”

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.
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.
EDITOR’S CHOICE: CHI has and always will be a powerhouse brand in the hair straightener industry, and the company’s new G2 Ceramic and Titanium Flat Iron is no exception! Packed with ceramic and titanium technology, this hair straightener was designed to give you silky, shiny styles without snags. We also love its easy-to-read, color-coded temperature settings, so you know the temperatures that you are using at any given time!
Do you have curly, dry hair? Thick, color-treated hair? Short, straight hair? Fine, kinky hair? Finding the right flat iron for you really depends on your hair type. Heat and plate types are an important factor in this. Your flat iron should reach and maintain the right temperature and be made from the plate material that works best for you. While most will work well on a variety of hair types, pay close attention to reviews from people with hair similar to yours (bonus points if they include before and after pictures).
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.
I started this site after I made the decision to get a new hair straightener. I am not a novice with irons by any means, and I’ve had just about every kind imaginable except for some of the newest options. When I realized how far the industry had come in the last couple of years, I decided it was time to try something new. A good flat iron can last for years, as long as you look after it and make sure you buy one that’s robust enough to take what you put it through. By doing your homework up front, you can make sure you not only get the right straightener for your locks, but you don’t end up spending an inordinate amount of money on something that doesn’t work for you. Believe me, I’ve been there!
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.”

Creative director of GLAMSQUAD Giovanni Vaccaro prefers this flat iron by Sedu. "The ceramic plates are really key to maintain the integrity and healthiness of the hair," he says. To get expertly straight hair, Vaccaro recommends using a boar-bristle brush to help mediate frizz, and that "the follow through is key" when moving the iron and comb completely from roots to tips.

Seemingly small details like cord length can make all the difference in the effectiveness of a beauty tool. A longer cord length is desirable here, giving you more freedom and versatility depending on the power outlet situation in your home or your hotel if you're traveling. A cord with 360 swivel capabilities is also a plus. You'll be moving your hair straightener all around your head as you style, and a rotating cord will keep it from getting tangled.

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.
