The question is, does it live up to all the hype? There are more than 30,000 reviews on Amazon, 70% of these reviews give a 5-star rating, and 14% give a 4-star rating. According to the numbers, the HSI Professional truly is a high-quality product that is well-deserving of the attention it's been given. Buyers love how quickly the HSI Professional heats up, what it does for their hair, and how easy it is to use— even on short hair.
There is a slide at the base which holds the device from opening all the way (easier for storing) but if you slide the piece it allows the flat iron to open all the way. The instructions inside the box don't explain this part, so at first I thought it didn't open very far, but once I figured this out, it became a breeze to use. Speaking of the instructions, they are listed in English, Spanish, French, and German. (I think... I don't speak/read all of those languages, but I believe that's correct.)
Weighing just over 1 pound, the BaByliss Pro Nano Titanium Straightening Iron is the lightest hair straightener on our list of the best flat irons! This lightweight design makes it a great choice for users that are constantly on the go, and even when traveling. In fact, this model might make a wonderful “second straightener” for someone that wants to keep their locks looking fine on the road without toting around their heavier at-home hair straightener!
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!
Hair breakage is an all too common problem, and even the most seasoned of hair stylists can slip up from time to time. That’s why LumaBella’s Keratin Duel Touch Hair Straightener features a unique smart heat sensor. This nifty little gadget can actually tell when there is too much heat for your hair, and will automatically adjust to a safer styling temperature!
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.
Heat stylers, such as flat irons, get a bad rap for singeing hair beyond repair, but that doesn't have to be the case. The key to preserving your hair's health while using these hot tools is passing a quality straightener over heat-protected strands without letting the heat sit on one spot too long. Speaking of stellar straighteners, here are 11 of our top picks, ya know, if you're looking to upgrade yours.
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!
The MHD professional flat iron hair straightener is great for creating loose curls because it’s got smooth plates and negative ions that leave your hair soft and frizz-free. The 3D floating plate allows your hair to glide through without catching or breaking, and reviewers love it because it’s durable, reliable, and works on any type of hair — even the most stubborn and frizzy.

I've owned a Conair, Chi, and I-Tech straighter before, but this one is FABULOUS! A lot of research was done before I made the decision to purchase this one, and I feel like it paid off; my previous straightener was 4 years old, so it was about time. I received this new one today before I got home for my lunch break, so I had to go ahead and bust it in ;) There really is no tugging at all on your hair - so smooth, and I was shocked that it truly heats up in 15 seconds, as advertised! It also does something magical to my hair, like it adds more shine like no flat iron has done before. Mind you, my hair is very difficult to deal with. I am a Caucasian, but my hair has always been coarse, wavy, dry and thick! This iron worked beautifully on my hair. 10/10 would recommend! If it doesn't work the same after a few months, I'll be sure to update my review. As of today, I'm very happy! :)


I ABSOLUTELY LOVE this hair straightener/curler. I was looking into buying the new TYME Iron that came out but found this one that was so similar and more than half the price. After seeing some reviews, I trusted it enough to purchase it. Got it in today and curled my hair (WITH my clip-on hair extensions) and it not only curls/straightens SO pretty but leaves hair nice and soft and silky AND therefore made my extensions blend in so so seamlessly. If you're looking for a new straightener/curler, I absolutely recommend!
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.
The type of heat you use to style your hair makes a big difference in how healthy it will be. Our Xtava Pro-Satin Infrared Ceramic Flat Iron for Hair uses infrared heating technology, which heats hair from the inside out. Infrared technology is a game-changer for styling your hair because it allows heat to penetrate directly into the inner part of the hair strand, not just the outside layer. Infrared heating to the middle of the hair strand provides a more effective heat for styling and decreases damage to the outside of your hair. Infrared technology also stimulates negative ions in your hair that draw oils from the hair shaft to the surface; this helps lock in moisture and lock in your look, even in humid weather. Better heat = better hair health. Guess that’s not much of a secret after all, is it?

If you’ve ever used a CHI hair straightener before, then you’re probably pretty well acquainted with the turn dial temperature control of models’ past. While this dial design made it easy to switch on your hair straightener each morning (even before you have had your morning coffee!), it also made it all too easy to accidentally change the temperature during use.
One of the Babyliss’ major drawbacks, and why we only recommend this flat iron for experienced users, is the outside gets hotter than any of our other picks. Hot to the point that it was too hot to hold. One tester said she was “afraid to accidentally touch the top of it.” Others said they could feel the heat against their scalps. At first, another tester said she didn’t mind the heat. This was moments before she burned the top of her hand when it merely grazed the side of the tool.
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.
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.
“Being a mom of two, it’s hard to have time to get my hair done, but with this, I do my hair in 30 minutes, rather than over an hour. I haven’t bought a new straightener in probably four years, and I bought this with very little expectations. OMG! First of all, not only did it take half the time to do my hair, but it left my hair as amazing as I always wanted it! Super silky-smooth. I then used it to make some curls on my 8-year-old. In less than 15 minutes, I was done with her hair and she was in love with the curls.”
If you have very thick, curly, or coarse hair, you may be wondering if xtava’s Infrared Flat Iron for hair can handle the job of hair straightening your locks - and we have good news for you. Our hair straightening iron has two key characteristics that equip it for the job: high, consistent, and even heat that can lock in your style and extra-wide, 2” floating plates that can handle a lot of volume.
To solve this problem, CHI’s new G2 Ceramic and Titanium Flat Iron features a digital temperature display located right on the outside of the handle.

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!
Available with either ceramic plates (good for all hair types) or titanium ones (choice for curly, thick, and coarse textures), this innovative styler features touch sensor technology that lowers the heat when it's not being used, then automatically brings it back up to temp as soon as it's touched. Translation: No more waiting for your iron to heat up in between passes. Use it for smooth and sleek styles, or take advantage of the round brush-esque attachments to create more of a bouncy blowout effect.
