Hair tools that use heat have a terrible reputation for damaging your hair. Sometimes it damages your hair so much that you end up with worse-looking hair than before. But flat irons do not really wreak too much havoc if they're efficient.

You should be looking out for efficient flat irons that can straighten your hair in one or two passes. If you're using an old one that has a lot of dirt and residue on the plates, or one that requires several passes for every section, then it's time to change your iron.

The general rule for choosing the best flat iron for thick hair is to get one that has broader and bigger plates, allowing you to cover more hair at once. But that's not the only thing that you should look for in a flat iron. You should also get one with a higher temperature setting and the right plate material.

Some like it hot

If you have thick hair, choose a flat iron that generates more heat. The thicker your hair, the hotter the temperature it needs.

It's just like ironing your clothes. If you are ironing thin fabrics, then use a lower temperature setting. But if you're doing jeans and heavy linens, then a hotter flat iron is what you need.

As such, a hair straightener with a higher upper-temperature range will work best for thick and coarse hair.

How would you like your plates?

When you search for the best flat iron for thick hair online, you will be presented with several options for plate material. Flat irons have plates made out of tourmaline, ceramic, ionic, and titanium.

Ceramic and ionic plates work best for those who have thin hair. These plates can distribute heat efficiently, but they don't get too hot. Because you don't get the temperature you need to straighten coarse or thick hair, ceramic and ionic plates are not that effective. You end up passing the iron on your hair several times and damage it in the long run.

Tourmaline is a semi-precious material that releases negative ions when you heat it. But real tourmaline plates are hard to find. Most flat irons available today have a ceramic plate that has a tourmaline coating.

Meanwhile, titanium is the best plate material for those with thick or coarse hair. These plates heat up quickly and transfer the heat to your hair excellently. It can also get really hot, which makes it the best flat iron for thick hair. You don't need multiple passes to straighten your locks.
