12 Best Flat Irons and Straighteners for Thick Hair

If you’ve got a lot of hair, you know getting through those gorgeous thick locks of yours can be quite the hassle. That’s why you want to ensure you are using the best tools for your hair for effortless (or at least lower effort!) and effective styling.

Styling thick hair doesn’t have to be hard or take hours of your time. It’s amazing how hair technology has progressed, and there are fantastic options out there.

Knowing what features your hair needs is the first step. If you have coarse or thick hair, this list has some of the best flat irons for thick hair types!

What to Look for in a Flat Iron

There are flat iron options in a variety of price points, so your budget will dictate some of your choices. Consider how often you plan to straighten your hair. If you will use it all the time for years, you’ll want to invest in a higher quality flat iron so it will last longer.

Straighteners can be used to curl your hair too. For a more versatile flat iron, go for one with slightly curved edges. This will give you a gentle curl rather than creating accidental stark creases in your hair.

Plate size can make a difference if you have thick hair (especially if it’s also long!). Wider plates will cut down on the time it takes to straighten your hair.

While thin haired women need to worry about damaging their strands with high temperature and take more care when choosing a hair straightener, your thicker hair can withstand higher heat.

As long as your hair isn’t prone to heat damage or frizz, shop for an iron with a higher temperature to make your styling process easier and faster.

What Type of Styling Iron Will Give You the Best Hair?

Are titanium or ceramic flat irons better for thick hair?

A titanium iron is one of the hottest irons you can use. This heat is what is going to permeate your hair and give you the desired hairstyle you want with a hot tool.

That’s why titanium over ceramic is the best choice for thick hair types when it comes to styling with flat irons.

Is a titanium or ceramic iron better for frizzy hair?

If your hair tends to be frizzy, a higher heat produced by a titanium iron may cause more frizz and damage. This is why a ceramic iron is the best pick for frizzy hair.

If you have thick and frizzy hair, a ceramic iron with a high-heat setting is the best for that hair type. There are also irons made with both ceramic and titanium plates, and you can find an iron like this at the end of my best flat irons list, so stick around!

Like all things, your hair is unique to you! If the first flat iron you try doesn’t do the job, don’t be afraid to try another one!
