For such a high-end flat iron, we were disappointed that the Babyliss doesn’t have a precise temperature display like the Bio Ionic. Our testers were confused by the settings, which had numbers going up to 50 vs. actual temperatures. The numbers represent a range, but you have to look through the instruction manual to figure out what that is. One tester summed it up perfectly: “I don’t want to read an instruction manual to use a hair straightener.”

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.”
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.
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.
While there are a lot of great options to choose from, our all-around top pick is the LumaBella Keratin Duel Touch Hair Straightener. Featuring unique, keratin-infused plates for optimal shine and less damage, the LumaBella Keratin Duel Touch Hair Straightener proves that technology really can make a difference when it comes to hair care! We also love this model’s innovative smart heat sensors that protect hair from heat damage and lock in moisture.
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.
Most buyers were happy with their purchase of the Xtava, loving how well it worked on their natural hair, how quickly it straightens and cuts down on style time, and the extra features like the heat resistant bag. Everyone should be able to have straight, sleek hair as a style option no matter their hair type, and it's well-designed styling tools like the Xtava Pro Satin that make it possible.
Try first flat ironing your hair from the roots on the lowest temperature on your flat iron, and straighten your hair normally. When you are comfortable with the way that you are straightening your hair, then you can start straightening your hair with the temperature that you would normally straighten your hair, but don't forget to use a heat protection spray so that you don"t damage your hair.
Despite these downsides, the HSI Professional comes with plenty of positives, including extras not often found with other hair straighteners. Along with the straightener, you'll receive a carrying case, a heat-resistant glove for easier hair styling, a style guide, and a travel-size argan oil leave-in hair treatment serum to smooth and protect your hair. This is more than most high-end hair straighteners come with, all for a fraction of the price.
This mini straightener is perfect for my bangs. I also used it to make some longer strands wavy by pulling it down at an angle. I bought it for travel abroad in Denmark since it has the dual voltage, but have only used it in the US so far. It heats up fast and makes my hair super smooth. And the free sample of conditioner smells soooo good and made my hair super soft!
At first, the Bio Ionic 10X Pro Styling Iron’s vibrating plates seemed gimmicky. But we were surprised at how effective they were when styling our hair. Our testers found the vibrating plates made straightening their hair go faster with virtually zero snagging. Engaging the vibration was also simple — click the power button and tap the plates together and you’re ready to go.

4. The button placement is very similar to the Remington flat iron. When the iron is powered on, quickly press the power button 2 times and a small lock icon will appear on the digital indicator under the Fahrenheit symbol. When the lock icon is visible you cannot change the temp or turn it off by accidentally pressing the buttons. To unlock, quickly press the power button 2 times again and the lock icon will disappear.
If you want to achieve sleek, pin-straight hair, a high-quality hair straightener should be in your beauty arsenal. A hair straightener, also known as a flat iron, smooths the follicle of your hair between two heated plates. Some hair straighteners can even do double duty, creating loose waves and curls without the frizz. So how to choose the best hair straightener for you, and get those shampoo commercial-worthy locks? There are several things to consider to make sure you'll get the best style result, but the most important is hair type.

The ability to create bouncy curls or waves with a flat iron (we know, it seems counter-intuitive!) is a biggie in the beauty industry and merits a bit more discussion. If you’re totally lost and there aren’t enough video tutorials on the planet to explain this weird yet awesome process, don’t worry! Just follow along with our step-by-step guide and you will be curling with the best of them in no time!
Nearly 21,000 people gave this flat iron a five-star review on Amazon. If they factored price into that rating, then I agree. For less than $60 it’s pretty spectacular, but it doesn’t beat the fancier ones in terms of performance. The temperature automatically drops after 15 minutes of use. And while it’s easy to adjust that, it is also slightly inconvenient.
