I have natural 4c hair and I have to pass the flat iron several times before it’s smooth. 

And this results in a lot of damage due to excessive exposure to heat. 

Most of the conventional straighteners are not designed to handle such hair textures. Even if they do, the results are often short-lived.

How I tested for the best flat irons for curly hair?

I first selected the top flat irons for curly hair available today and tested them on the basis of the following factors. With help from my team, I then rated them on a scale of 1-5.

  • Plates – Curly hair requires flat iron with materials like titanium or tourmaline
  • Multiple Temperature Settings – As curly hair can be fragile, the multiple heat settings let you control heat distribution
  • High Maximum Heat – Curly hair requires a temperature of upto 450F to change hair textures to smooth.

It is actually hard to believe because if you straighten curly hair, it always looks far from professional work. 

This also worked so well and took so much less time than the rest of the straighteners in the list. 

I like that it comes with flexing plates that make sure that every inch of your hair is styled evenly. 

It is very common to have frizzy hair after using a flat iron on curly, but I was surprised to notice that my hair looked exceptionally smooth!

Dryson always manages to combine the latest technology in their products to give you a seamless customer experience. The cordless feature is great for those who want to use it on the go. 

It is very common to get flyaways and tiny curls sneaking out when you straighten curly hair. This hair straightener is great for taming those annoying top-ups and flyaways. 

Although this is a little on the pricier side, I’d say the results are pretty worth it. 

The best part about this straightener is that it has the ability to straighten large sections of hair in one go. 

You can even expect your style to stay until the next hair wash after using this straightener.

These flat irons have steam vents that have the ability to convert the water from the hair into moisture before straightening it.

Tips for straightening curly hair with a flat iron

Wash and condition your hair– When you are planning to straighten your curls, the preparation starts at the shower. 

See also  Routine Shampoo And Conditioner Review | Is It Worth It?

Wash your hair with a straightening shampoo. This will help in removing frizz and smoothing out your hair. 

You should follow up with a conditioner or hair mask that is formulated for removing frizz. 

Moisturize your hair- Curly hair usually tends to be dry and fragile. 

So it is important to supply an adequate amount of moisture in the form of oils, leave-in conditioners, hair creams, etc. 

Always select products with moisturizing ingredients like coconut oil, shea butter, argan oil, etc. 

You can also pre-poo your hair before the shower using any oil or mask to get that frizz-free hair. 

It is important to keep frizz at bay when you are styling your hair. You can apply these products to both dry and damp hair.

Use a heat protectant- When you use heat tools, some amount of heat damage is bound to occur. 

This could further lead to thinning and breakage of your hair. So it is important to use a heat protectant spray or cream before using any heat tools on your hair. 

People with curly hair need to blow dry their hair before using a flat iron so a heat protectant is essential. 

Blow-dry your hair- Curly hair is difficult to dry and it might still have patches of wet hair. So it is important to make sure that your hair is completely free of moisture. 

To ensure this, you have to section your curls and blow dry each section separately before using a flat iron on them. This should be done after using all the pre-styling hair products on the hair. 

Maintain the style- To make sure that the straightened look stays intact, you have to practice certain things. 

After you are done straightening your hair, use a hair spray on it. You can look for something with a medium hold that will make your hair look naturally straight. 

You can also switch your regular pillowcase with a silk/ satin pillowcase that reduces friction and maintains the hairstyle. 

Those were some of the best flat irons for curly hair. As curly hair is more prone to breakage and dryness, I strongly recommend using a heat protectant before straightening.

Also, a serum or leave-in conditioner will help keep frizz away and make sure your locks are moisturized.
