Best Flat Irons for Thick Hair Rated and Reviewed for You

Thick hair can be beautiful to look at. But, at the same time, it can be impossible to manage. This is especially true if you prefer a straight look to your naturally curvy or wavy one. Finding the best hair straightener for thick hair makes straightening your hair a much easier task.

Thick hair has lots of natural volume and body. That's the good news.  Precision temperature control, high heat range, plate size and materials are critical to choosing which flat iron is right or you. Wet to dry technology can shorten styling time. While floating plates can help them glide smoothly through your hair without pulling or tugging.

With so many different models available on the market, it can be rather difficult to choose the best flat iron for thick hair. But don’t fret. We have gathered five of the best hair straighteners specifically designed for your hair.

Top Five Hair Straightening Tools for Thick Hair

1. Turboion Rbb Croc Classic Straightener - Black Titaniun


The Croc Turboion hair straightener is an essential hair tool that can help reconstruct and recondition the hair. This unique flat iron may look a little strange but it provides great performance and results. Designed with 1.5 inch ceramic plates, this iron heats up quickly and cools down quickly.

This flat iron also comes with digital temperature control on the handle and will heat up to 450 degrees.  You can control the heat setting of the tool to meet all your styling needs. Lightweight and easy to use this may be the best straightener to keep your hair soft and shiny hair all day long.

2. CHI PRO G2 Digital Titanium Infused Ceramic Flat Iron


The CHI PRO may just be the perfect tool for you. This flat iron comes with inch titanium infused ceramic plates, accurate temperature control and a dial for easy temperature adjustment.

You can always set the right temperature depending on your needs. Temperature range for this iron extends up to 450 degrees. There are also programmed settings for fine, medium or coarse hair if you are looking for simplicity. This flat iron is lightweight and is easy to carry. If you have thick hair with waves and curls, you will find this iron to be easy to maneuver and achieve your desired style.

3. Sedu Revolution Tourmaline Ionic Styling Iron


One of the unique features of this Sedu styling iron is the rounded edges of the tool’s straightening plate. This design prevents the hair from developing crimp marks and allows you to create almost any style you desire. Designed with tourmaline infused ceramic plates, it provides even heating without damaging hair. And this flat iron comes with a fully adjustable temperature scale that ranges from 180 to 450 degrees. With the adjustable settings, you can always find the right heat setting for your hair.

One drawback of this flat iron is its weight, as it is rather heavy compared to other flat irons in the market. That is a trade-off to weigh against the quick styling benefits of its accurate, high heat capabilities.

4. Hai Convertible Ceramic Flat Iron


The Hai Convertible uses both ceramic plates and ceramic fusion technology working together to seal in moisture, reduce frizz and prevent hair damage. You can choose from different plate widths as this flat iron is available in 1 inch to 1 ¼ inch irons.

This flat iron also comes with adjustable temperature control that can heat up to 390 degrees. This hair straightening tool heats up fast and holds heat evenly. Now, you can style thick hair quickly and easily with this unique iron.


This Babyliss iron is designed with extra long nano titanium plates, which is perfect for long and thick hair. Compared to tourmaline and ceramic plates, titanium plates are smoother.

With its high heat range of 450 degrees,  this iron is great for straightening even the most frizzy, curly or coarse, thick hair. It also makes use of infrared heat to seal in natural oils and moisture and achieve that shiny, healthy and salon straight appearance.

While it is one of the best flat irons for thick hair, it is not the best choice for those with fine hair. The temperature settings may not get low enough for fine hair. On the bright side, this flat iron does have accurate temperature control with an LED display. So you can easily dial in the perfect heat setting that works best for your type of hair.


Thick hair can be  difficult to manage and require multiple passes of your flat iron especially if it is long, wavy or curly. Definitely frustrating when you're in a hurry and you don't want to leave the house without looking your best. And, of course, getting that soft feel, shine and straight style while being gentle on your hair are important considerations as well.
