When it comes to picking the best flat iron for thick hair, you might not know where to start. Whether you battle with frizz or just have super dense curls, it can be difficult and time-consuming to straighten thick hair with that $10 flat iron you’ve been using for 3 years. On top of that, poor quality flat irons can cause extra damage because you typically need to turn up the heat to maximize results and save time.

A high-quality flat iron for thick hair can cut down styling time, minimize damage, and give you gorgeous frizz-free results! We’ve put together a list of the top picks based on in-depth research, reviews, as well as our own trial and error.

Best Flat Irons for Thick Hair

Dyson Corrale Straightener

Price: $499.99

If you really want to make an investment, the Dyson Corrale straightener is the luxury flat iron you’ve always wanted.

It offers three heat settings (up to 410 degrees) and uses flexing plates to gather more hair, allowing for quicker straightening. It also has auto shutoff, so you never have to worry about burning the house down.


Babyliss Nano Titanium

Price: $149.99

This lightweight, smooth flat iron features 5 extended plates to help you quickly straighten any type of hair.

It has 50 heat settings and reaches up to 450 degrees. It’s also available in 3 sizes (1-inch, 1.5-inch, or 2-inch).


Paul Mitchell Express Ion Smooth+ Flat Iron

Price: $125

When asking a few different hair stylists, they highly recommended this Paul Mitchell styler.

It heats up to 410 degrees, with 1-hour automatic shutoff and dual voltage (meaning you can take it with you when traveling overseas).


PYT Hair Straightener

One of the more affordable options on the list, the PYT flat iron is another top pick by those with thick hair.

It heats up to 450 degrees, with dual voltage and heats up in just 10 seconds. If you need quick straightening power that lasts all day, this is a great flat iron.


GHD Platinum+

This unique, award-winning flat iron is considered a “smart styler” because it recognizes hair thickness and speed of styling, adjusting the temperature for optimal results. It monitors the heat to maintain a 365-degree optimal styling temperature, resulting in less breakage and stronger hair.

It’s available in a few different colors and can be used to create a variety of hairstyles (not just straightening).


Bio Ionic 10x Pro

Price: $230

The Bio Ionic is well worth the investment. With vibrating plates and natural volcanic mineral infusion that help quickly smooth hair while keeping it shiny, get ready to have the best hair of your life. It heats up to 450 degrees with dual voltage and 1-hour automatic shutoff.

Plus, the unique-looking rounded tip allows you to easily use this tool for a lot more than just straightening.


Revlon One-Step Hair Dryer

Although technically a hair dryer, this brush hair dryer combo is worth the mention.

It’s definitely worth a shot if you’ve never tried it before! It significantly reduces frizz, which many of us with thick hair struggle with. It doesn’t completely straighten while drying, but it gives a lovely semi-curled affect similar to a blowout. If you want super straight hair, you can use your flat iron afterwards (and it will be a lot easier to do so).


Bottom Line

These are some of the best flat irons for thick hair to get the best results and cut down on styling time. Whether you spend $500 on the Dyson or go for a more affordable pick, get ready for jaw-dropping results that will leave you wondering why you waited so long to switch up your flat iron!
