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!
