How to Choose the Best Flat Iron for Curly Hair?

If you want the best results, there are a few things to take into account when buying a flat iron for curly hair. Let’s take a look!

Ceramic Vs Titanium

So, you’ve come across ceramic as well as titanium hair straighteners. Which one should you choose? Well, it depends on your hair type. Titanium plates heat up really quickly and can reach higher temperatures than ceramic plates. 

For someone who has thick, curly hair, titanium flat irons would be a great choice. On the other hand, if you have really fine hair, ceramic flat irons would make more sense as they’re less damaging. 

Ceramic irons transfer less heat which results in less damage. They’re usually combined with tourmaline and promise great results. 


It’s also worth considering the maximum temperature a tool can reach. Thick, curly hair requires a tremendous amount of heat to straighten. In such a case, you should go with irons that can reach a temperature of up to 450 degrees F.

Additionally, it’s a good thing if the tool has various heat settings. That will allow you more control and precision over your styling. 

Plate Size

It’s a matter of personal choice. But if you have long hair, go for plates that are 1½ inches wide. For someone with shorter hair, a one-inch plate will do the trick just fine.

Additional Features

Check if the iron has an auto shut off feature. This should not be a deciding factor but it’s good to have all the new features, right? Plus, it would give you some sense of security in case you forgot to unplug the device. 

Another thing to look out for is the design. You would want the on/off button at a place where you don’t accidentally turn it off while styling. Also, the iron should be easy to handle. 


Should I buy ceramic or titanium flat iron?

As we’ve mentioned above, titanium flat irons are a great choice if you have naturally thick, curly hair. Even the salon professionals use titanium flat irons because they work fast and can transform even the most stubborn curls. 

How long will my hair stay straight?

It depends on a number of factors including your hair type, texture, weather conditions, the quality of flat iron, etc. But you can expect your hair to stay straight for a day or two. And the moment you wash them, they’ll get back to the way they were prior to straightening. 

Can I use a hair straightener without using heat protectant spray?

It’s not a good idea to straighten your hair without heat protection. The last thing you want is damaging your tresses. Never forget to use heat protection spray while using a flat iron. 


The end result will depend greatly on the quality of the flat iron you use. So, it’s important that you choose the right product. Luckily, the flat irons we’ve reviewed above do a really good job of straightening the tresses no matter your hair type. 

Just make sure you know how to properly use an iron. You can read the instructions provided by the manufacturer. It’s important to separate your hair in sections.
