It has settings for different amounts of heat needed to straighten various types of hair. You should not use the highest setting unless your hair is very unruly with lost of natural oil. It is a well known fact that some straighteners can leave your hair hard and flat. This will never happen with model. Your hair will not get “cooked” even with daily use.

We loved the Bio Ionic’s user-friendly design. Two of our favorite features are its bright digital temperature control and the instructions stamped directly onto the tool. It also feels natural in the hand, and its matte finish provides a slight grippiness, but doesn’t pull at the hair when styling. Plus, the tool sports a uniquely shaped plate that’s curved at the tip and makes it really easy to get close to the scalp. One tester who is new to using flat irons said the Bio Ionic felt intuitive and even encouraged her to try harder styles, like creating curls and waves.
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!
It comes with the most advanced heating element in this industry. Using a digital display, you can adjust temperature from 280F to 450F. This means that you can use it to style fine or very fragile hair as well as very thick and coarse. This is the model that is often recommended for women that have hair that is hard to straighten and difficult to keep straight. So if lower heats do not work for you, use the highest setting, and get pin straight results, like glass.
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.”
Now that you know what the Xtava Pro is capable of, it's worth running through the features that make those results possible. Along with the solid ceramic plates for even heating, there are 10 temperature settings to choose from for optimal styling control. The temperatures are shown on an easy to read digital display and range from 265 degrees to 445 degrees Fahrenheit.

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.
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!

The plates of the HSI Professional are made of solid ceramic that is infused with tourmaline. The combination allows for consistent temperature and gives hair a smooth finish. The wide range of heat settings, starting at 140 degrees Fahrenheit and going up to 450 degrees Fahrenheit, gives you more control over styling and makes this an ideal straightener for multiple hair types.
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.
Aside from ionic and infrared technologies the Bio Ionic Onepass Straightening Iron has something that is entirely new to me: silicon covered plates. They get the hair more in order when you’re straightening, save you a lot of time and reduce the amount of heat that you need. This one is great for African American hair, but I already selected the xtava Pro Satin for that because it’s more affordable.
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!
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.
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:
The Lanxim ceramic tourmaline argan oil flat iron is a great option for this type of style because it’s got one inch plates that have advanced infrared heat technology, an adjustable temperature that lets you personalize the heat levels to your hair, and a swivel cord that won’t get tangled. The floating plates are also infused with argan oil to keep your curls soft and healthy.
Before placing your entire head under unnecessary heat conditions, try straightening a small section of your hair with what you believe is your ideal heat setting. Take notice of the way your hair reacts to this temperature, paying close attention to any fraying or singeing that may result. Smoking and that dreaded burnt hair smell are a sign that you may need to tone it down a bit to avoid permanent damage to your precious locks.

Here at the Strategist, we like to think of ourselves as crazy (in the good way) about the stuff we buy (like pillows), but as much as we’d like to, we can’t try everything. Which is why we have People’s Choice, in which we find the best-reviewed (that’s four-to-five-star reviews and lots of ‘em) products and single out the most convincing. While we’ve written about the best curling irons, hair dryers, and even a certain curling iron used on the Victoria’s Secret Angels, here, we’re going deep on the best flat irons and hair straighteners on Amazon. (Note that reviews have been edited for length and clarity.)
"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.
Coming in at a close second, the CHI G2 Ceramic and Titanium Flat Iron is our second editor’s choice as the best hair straightener on the market today – featuring fool-proof and color-coded temperatures for easy straightening or who just wants to protect their luscious locks. We also love the digital display that is featured on the CHI G2 model along with its combination ceramic and titanium design for optimal shine!
The BaByliss Pro Nano Titanium Straightening Iron really is the Baskin Robins of hair straighteners, making it the perfect choice for anyone that wants to straighten their hair quickly. Whether you have naturally short hair and opt for extensions on occasion or you just chopped off your do’ into a new pixie cut, you will have a hard time not finding the perfect heat setting for your hair so many choices!

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.
With a maximum temperature of 450° F, the BaByliss Pro Nano Titanium Straightening Iron can really pack a punch despite its otherwise small frame. One thing to note though: these heat settings are not pre-set like the CHI G2 hair straightener we also reviewed, and you will need to play around with them to find the right temperature for your hair. This shouldn’t be a problem if you have a Saturday afternoon or two to kill, but may not be ideal for users that are looking for a flat iron with pre-recorded settings.
