Best Flat Irons Straighteners for Thick Hair
Thick hair can be exceedingly beautiful to look at, but at times it can be nearly impossible to manage. Keeping control of your hair is even harder if you prefer a straight look rather than a naturally curly one.
In the world of hair styling, your hair will fall under one of 4 hair types, numbered 1, 2, 3, and 4. Thick hair will typically fall under types 2B, 2C (Medium Wavy and Corse Wavy, respectively) or 3A (Loose Curls). For more on hair types and you can check out wiki here.
This hair is thick, often with lots of natural volume and body, and will almost always be curly. It may also tend toward frizziness.
The good news about thick hair-
- It is less likely to get damage (still need to take care of it with a heat protectant),
- A good styling will almost always show lots of volume and bounce
- You can practically do any hairstyle you feel like on any given day.
The bad news is you have a lot of hair-
- It's stubborn
- It takes forever to dry
- But even longer to style
How we grade out Flat Irons
The best flat iron for thick hair needs to be efficient, hot, and easy to use to make sure that your stubborn hair succumbs to the stylings of your desire. When we tested our flat irons for thick hair we graded them on four different categories; design, heating, performance, and value. Here is a quick rundown of each group for you.
Design- No matter how great the flat iron that you are using on your thick hair it still takes time to make it do what you want. That time can be cumbersome if the design of the flat iron is subpar. We look for light, comfortable to hold, easy to use, and safe, flat irons. Good designs keep from you burning your hands and hair, is simple, and lightweight for all your long sessions of hairdressing.
Heating- We measured how hot the irons get and if there were any cold spots over time with repetitive use. Heating is essential, and you want your flat iron precise with the temperature with no cold spots or uneven heating.
Performance- We look at all the features of the flat iron and compare them to the field here. We see if a safety shut element is present, how easy it is to set or change temperatures, and does the flat iron heat up fast. Any bonus features a flat iron might have we take effect here. The long in short of the story here, however, is did the hair look and feel great after stylings.
Value- This one is straightforward. To figure out the value of the flat iron we compared the cost to all the other categories. The better it performs and least it cost the better the value you get!
Top 5 Flat Iron Straighteners for Thick hair
BaByliss PRO has been one of the staples in the industry for a reason. The little blue beauty is super lightweight and easy to hold and use. The design is near perfect with clamps and the heating dial easily accessible for the user. The power cord swivels at the base of the flat iron making it easy to move around your head without worrying about where the wire is. We fell in love with the design the minute we held the BaByliss PRO Nano Titanium in our hands.
The Babyliss PRO's titanium plates heat up fast, are precise, and stay hot at a max temperature of 450°. This flat iron packs a wallop when it comes to heat (again friendly reminder USE A HEAT PROTECTANT). The titanium plates heat up extremely fast, and our test showed an even heat all across the plates. Our only complaint is the dial goes from 1-50 and does not have an actual temperature readout or else it would get a 10 out of 10.
In all of our testing the irons get hot fast, you can clamp down on the hair with ease, and passing through thick hair was no problem. We were able to straighten, wave, and curl to our desired results with the Babyliss flat iron and have no complaints about how well it performed.
This flat iron is worth the investment plain in simple. We have tested, tested, and tested again and we look for another iron to take its place as the best flat iron for thick hair..... Yet here we are with another update, and it is still #1. We do not give it a full 10 out of 10 on value however because it is one of the more expensive flat irons and we do have some others on this list that are less expensive and still provide enough features to be solid values.
Verdict- BaByliss PRO Nano Titanium Straightening Iron is still in our eyes the best flat iron for thick hair. It gives you everything you want and need in a flat iron. So get ready thick hair to meet your match with the BaByliss PRO.
The Sedu Revolution Tourmaline Ionic Styling Iron provides a minimalist design that makes it light and simple to use. A digital readout on the outside lets you know what the temperature of your iron is at all times and is very convenient. The irons are well placed, and it is easy to clamp down as you pass hair through the iron. We are not a fan of power and temperature settings being on the inside of the iron which is why the Sedu did not get a 10 out of 10.
Sedu Revolution uses ceramic plates infused with black tourmaline to displace the heat evenly. Our test showed a reasonably accurate temperature reading on the plates compared to the settings. The plates did take a little bit longer to warm up compared to the BaByliss PRO when tested side by side but still got hot fast.
We love ceramic plates, and the passes through your hair were smooth and seamless as you glide through your hair. The gemstone infusion of tourmaline in the plates eliminate any frizz and left hair silky and smooth. We could not ask for a better performance from the Sedu Revolution.
In the same price range as the BaByliss PRO, it is on the higher side of flat iron costs. With that said you get your money's worth. The price is justified for the type of performance and flat iron you get.
Verdict- The Sedu Revolution gives BaByliss a run for its money. Honestly, it comes down to preference on which one you should get. If you prefer ceramic irons or even want a digital readout of the temperature, then we suggest getting the Sedu Revolution.

The Hai Convertible Ceramic Flat Iron has a sleek design and lightweight design. The plates clamp together evenly and with ease making the passing of hair through the plates effortless. There is no digital readout however the temperature dial does have the degrees listed out, so you have a good idea how hot the plates are. Again we wish the buttons were on the outside of the iron like the BaByliss, but that is just being picky.
This Hai flat iron had the most accurate heat readings we tested of the irons we tested this time around. The 1.25'' ceramic plates heated up evenly and incredibly precise to the settings of the temp dial.
With Hai's precision heating comes the need to wait a little bit longer than both the Sedu and BaByliss to heat up. With that said you won't be disappointed after the wait. With the Hai flat iron, you will get smooth, seamless passes through your hair and even the thickest of hair that we tested needed one and at the most two passes to get the desired hairstyle we were looking to create.
The Hai is a step down in price range from the Sedu and BaByliss and still held its own in testing. As far as value goes, that is all you can ask for less money similar results. If this iron had a couple more features like slightly better design or a digital thermostat, it would get a 10 out of 10 instead it still scores a 9.5.
Verdict- If you want to save a little money from our top tier flat irons this iron is the perfect step down. The money you save is not lost in performance and makes for a savvy purchase.
The salon tech titanium is one the larger flat irons we tested. The design does have the temperature dial on the outside making it easier to change the temperature while styling. The larger handle and design can become cumbersome on more extended styling sessions. The last little design flaw we found is that it does not work well with converters. If you are traveling abroad, you should check out our best dual voltage flat iron guide here and purchase a different iron.
Man do titanium plates heat up fast and evenly, and the Salon Tech's 1-inch titanium plates are no exception. Our temperature readings were pretty accurate, and the heat was evenly distributed throughout the plates.
The Salon Tech Titanium held its own in performance testing. The titanium plates are only coated with titanium, and we could tell as we did not get as smooth of passing as we did with the better performing irons. We were able to get the desired hairstyles we were testing for even on the thickest of hair, so it still gets higher scores in performance.
In the same price range as the Hai, you get a lot of bang for your buck with this iron. It does score lower than the Hai because speaking frankly the Hai did better in testing and at the time of writing this is slightly cheaper.
Verdict-Salon Tech is a well-known industry leader in beauty. They offer warranties on all products, so this is one of the safer buys on the list. With that said in the price range the Salon Tech Titanium 450 Flat Iron we would probably go with the Hai.

The newcomer to our list in the latest update is the HSI's The Glider. We loved the digital temperature settings and button controls as opposed a dial. It was a bit confusing why the digital display is on the inside of the iron. We wish it were somewhere on the outside so that you could quickly check while you are stying your hair.
Accurate, quick to heat up, and evenly distributed heat in all our testing. The Glider's titanium plates tested very well with all our readings. We would like to make a quick note here- We pride ourselves to check our irons over and over again to see if the results are consistent over 500-1000 usages. At the time of writing this, we have not tested this iron as much as the other 4, so we cannot speak to the longevity or accuracy over time yet.
After a couple quick and effortless passes through the hair, we started to see why so many reviews on Amazon enjoy this iron. The clamping of the irons together was a bit further than we would have liked, but with thick hair (all we tested on it) that was less of an issue. The rounded edges of the irons also made it much easier to wave and curl the hair.
We would consider this in the upper tier of price, but you do save a couple of dollars with The Glider than Babyliss or Sedu. This iron has everything you could want in a luxury iron and justifies the cost.
Verdict- We are starting to fall in love with this iron. There are a few complaints like buttons and digital temp reading on the inside, but this iron held its own against the BaByliss and Sedu. Overtime if the quality of the iron remains the same with multiple usages, this might overtake our top irons in the future.
When you have thick hair, you need top performing well heated flat irons. These irons we have tested and will give you the results you are looking for to help tame even the thickest of hair.
