Top 10 Hair Straighteners Of 2020 Reviewed

1. HSI Professional Glider

Hair Straightener Dual Voltage

This Amazon bestseller has just about everything you’ll need in a hair straightener. The 1-inch plates are high quality ceramic and tourmaline plates for silky smooth results. These plates feature 8 HeatBalance microsensors that ensure temperature remains consistent and evenly distributed throughout. Plus, these are floating plates with curved edges so you don’t have to worry about snagging your hair while you style because the plates adjust the angle as you do your ‘do.

With this hair straightener, you also get adjustable heat settings that range from 140 to 450 degrees Fahrenheit which means that it’s perfect for use whether you have thin, delicate hair or stubborn, coarse locks. We love that it has a 360-degree swivel cord, it heats up quickly, and the fact that it’s dual voltage compatible. You even get a thermal protective glove plus some leave-in argan oil with your purchase.

However, there are some areas for improvement. There is no temperature indicator or display so you don’t really know how hot the iron gets. Also, the on/off switch and temperature dial are awkwardly placed; they’re inside the flat iron which isn’t really the best place for them.

HSI Professional Glider


  • Variable heat settings
  • Floating ceramic tourmaline plates
  • 360-degree swivel cord


  • No temperature display or indicator
  • Awkward placement of on/of switch and dial

2. Infiniti Pro by Conair Tourmaline Ceramic Flat Iron

Hair Straightener For Curly Hair

The InfinitiPro by Conair has extra-long 1-inch tourmaline ceramic floating plates with 30 different heat settings (maximum heat is 455 degree Fahrenheit) and an extra long swivel line cord. It is perfect for creating silky smooth, straight hair or shiny curls. You can use it whether you’re hair is delicate, medium, or thick and hard-to-straighten. AND it has an automatic shut-off feature. It only takes 15 seconds to heat up which means that you can style your hair pretty quickly. However, like our first pick, the settings do not indicate the temperature. Also, the handle can get very warm. The plates also do not completely close unless you put quite a bit of pressure on them. It also doesn’t feature a safety latch that will keep the flat iron closed when you put it down while it’s still hot.

It has LED temperature settings that reach up to 450 degrees Fahrenheit. The Ryton housing ensures that you never feel the heat in your hand even when the temperature’s at maximum.

We love the fact that the ceramic heater ensures the iron heats up super fast. Even better, you can be sure that you’ve got all that unruly hair under control in 10 minutes or less (expertise required, of course). While there’s a lot to love about the BabylissPRO, it doesn’t have an automatic shut off feature. It also is a bit heavy and bulky. And the price isn’t anything to sniff at either.

The temperature is adjustable from 250 degrees Fahrenheit to 410 degrees Fahrenheit. And we really love the fact that the dial shows you exactly what temperature you’re getting whenever you turn the heat up or down. Negative ions help smoothen your hair strands, leaving them silky and shiny.

The 9-foot power cord means you never have to worry how far away the outlet is from where you’ll be styling your hair. It is more expensive than some of our other picks but it’s not as expensive as the BabylissPRO. However, it doesn’t have an automatic shut off feature and the temperature range only reaches 410 degrees Fahrenheit. Also, there have been reports from users that their HAI Classic only lasted a year or two.

The heat can reach up to 400 degrees Fahrenheit; not as high as our other picks but definitely high enough for most hair types. However, for those with stubborn, coarse hair, you may want to look elsewhere for your hair styling needs. Also, this is one of the priciest hair straighteners we’ve tried so you’ll need to save a bit to splurge on this one.

It heats up very fast and cools down just as quickly so you can easily pack it away if you’re in a hurry. The plates are 1.5 inches wide which is perfect for long, thick tresses.

However, it isn’t always one pass as the name states. But it won’t require you to pass through the same section of hair more than three times which still means less time spent styling and less damage done to your hair.

Hair Straightener For Black Hair

Unlike all the other hair straighteners on our list, the Turboion RBB Croc Classic looks a little bit different. It looks more like its namesake – a croc. But that’s not the only thing that makes it stand out. First of all, the shape is unique and perfectly ergonomic. It fits very comfortably in your hands that you barely feel the strain as you style your hair. Of course, it also doesn’t hurt that it only weighs 1 pound. The smooth titanium plates on this flat iron gives you a very smooth glide. There are 17 different digital heat settings that range from 280 degrees Fahrenheit to 450 degrees Fahrenheit.

We do love the fact that the flat iron remembers your last heat setting so you don’t have to keep changing it every time you turn the hair straightener on. With this flat iron, you also get an automatic shut off feature. The plates are 1.5 inches wide which makes it ideal for individuals with medium to long thick tresses. However, it isn’t ideal for making curls due to the large plates. Also, there may be durability issues as several owners have reported that their units never lasted more than a year.

How to Choose the Best Hair Straightener: the Ultimate Buying Guide

One of the best investments you’ll ever make for your hair is buying a flat iron or hair straightener and hair drier. It’s one of the most versatile hair tools you’ll ever use. It can help you create curls (kinky or beach-blown waves), flirty flips, or super straight hair. Even the most coarse, unruly hair will bow down to the will of a good flat iron.

But like most tools, you need to invest in the best. And what’s best for others does not make it best for you. The wrong choice can cause damage to your hair. So before you head out to buy the first hair straightener you see, let’s talk specifics.

What’s the Plate?

The plate is the part of the hair straightener that heats up and used to press your hair. Now, hair straighteners come in different plate materials and sizes. Most plates have a width of 1 inch which work for most people and that’s perfectly fine. However, to really get the most out of your flat iron, you’ll need to consider your hair and styling needs when deciding plate size.

If you have really short hair, you’re better off with a narrow plate, around half an inch in size. If you want to curl your hair, smaller plates are also ideal. For those with longer, thicker tresses, you need wider plates, around 1 1/2 inches, to ensure that you cover more area on each pass. This decreases the amount of passes you need to make, preventing more damage done to your hair.

Should I get Titanium, Tourmaline, Ionic, or Ceramic?

As we’ve already mentioned, there are different materials used to make plates.

Ceramic irons heat up quickly and distribute heat evenly. These irons don’t have cool spots so you can be sure to get an even straightening every single time. These are ideal for those with fine, thin strands. Just be aware that not all flat irons marketed as ‘ceramic’ are pure ceramic. Some only feature a ceramic coating which wears off over time, causing damage to your hair.

What about ionic? Well, ionic just means that the flat iron emits negative ions that counteracts the effects of positive ions in your hair (i.e. frizz) which ensures you get a smooth, frizz-free, shiny look. All ceramic irons are ionic.

Tourmaline is an organic, prismatic crystal found in granitic rocks that is crushed into a fine powder and layered onto the surface of the plate. Tourmaline is great because heat is more consistent and evenly distributed through the plate. Also, it produces more negative ions than ceramic with less heat. This means that you not only get more control, but you also get better results and expose your hair to less damage. It’s the newest entry in the heat styling industry so hair straighteners with tourmaline tend to be pricier. Some hair straighteners like the HSI Professional Glider infuse both ceramic and tourmaline to boost the number of negative ions produced.

If you have stubborn, never-listens-to-me-no-matter-what-I-do hair, titanium is the material you need to set your eye on. Titanium is a metal that is excellent at conducting heat which means that your plates heat up quickly. This metal also keeps heat consistent so there are minimal changes in temperature that could damage your hair in the long run. What makes this great for thick, curly, unruly hair is that it can reach and maintain a high heat for quite a bit of time AND emit 60% more negative ions than ceramic. These two characteristics mean that you get to de-frizz your hair in a shorter amount of time with fewer number of passes.

What About Temperature?

The best hair straighteners should offer you adjustable temperature settings so you can customize it depending on your hair type. This is incredibly important if you have thin/fine, delicate, or damaged hair because it allows you to ensure that the iron doesn’t get too hot for your hair. Basically, having the ability to set the temperature/heat setting gives you more control. But if you prefer to have a set temperature, then you should take note just how much heat your hair can take and how hot your hair straightener can get.

Fine, delicate hair requires lower heat as it can get easily damaged. It’s best if you can get a hair straightener with an adjustable temperature feature with a minimum heat setting that’s below 180 degrees Fahrenheit.

Thick, coarse hair can withstand high heat AND it responds better to it. Using high heat also means that you minimize the number of passes you’ll make which will benefit your hair’s health. You’ll want a hair straightener that has adjustable heat settings with a maximum temperature reaching the 400-degree range like the HAI Beauty Concepts 1.25″ Classic Convertable Flat Iron.

For normal to medium thick hair, the ideal temperature is somewhere between 300 to 350 Fahrenheit. If the length is below the shoulder, experts recommend the heat setting 360 to 380 degrees Fahrenheit. If you can, choose a model that has a digital panel. This allows you to see exactly how much heat the hair straightener is pressing onto your hair at any given time.

How Light is the Hair Straightener?

Ok, you gotta admit that by the time you’re done applying product to your hair and blow drying it, your arms are starting to get a bit tired. So, you better make sure that the hair straightener isn’t going to exacerbate that feeling. You are, after all, weilding a very hot tool near your face and neck.

You need to make sure that your flat iron is very light, feeling comfortable in your hand as you style your hair. You’ll also want it to have a tangle-free cord because that’s just a hassle you don’t want to have when you’re focusing on doing your ‘do right. Or, you can just go for a cordless hair straightener to get rid of that potential problem altogether.

Is there an Automatic Shut-off Feature?

This safety feature ensures that you never have to worry about forgetting to turn off your hair straightener, especially when you were in a hurry to get going. Flat irons with this feature automatically turns off after 60 to 80 minutes of run time. The  Infiniti Pro by Conair Tourmaline Ceramic Flat Iron, for example, shuts down after 60 minutes so you never have to worry that you’re coming back to a burned down house just because you forgot that your flat iron was still on.

Does the Housing of the Hair Straightener Stay Cool?

While the metal part of your hair straightener heats up, the housing – the part that you hold in your hand – should remain cool to the touch. For example, the BaBylissPRO Nano Titanium-Plated Ultra-Thin Straightening Iron features Ryton housing that ensures the handle doesn’t heat up along with the plates.

Remember, quality is an important requirement when it comes to getting the best hair straightener for your hair. if you want to look good when you step out there, then pick the right one. A poor quality flat iron is not only going to work very well, but it could also cause damage to your hair that may take a long time to grow back. If you want good styling AND ensure the health of your hair, the best hair straightener is one that doesn’t come cheap.
