The 6 Best Flat Irons For Curly Hair 2023 | For Easy Hair Straightening

Here are some best flat irons for curly hair that help straighten curls into smooth straight locks in an instant. Also learn a few tips on how to keep straight hair frizz free.

People with curly hair generally find it difficult to straighten it. So you need to select the best flat iron for curly hair.

As curly hair is usually thick and rigid in structure, it becomes a little difficult to manipulate the hair texture. 

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.

How To Choose The Best Flat Irons For Curly Hair

Having curly hair is a blessing, but it can also be a curse when it comes to styling it. A flat iron is a must-have tool for anyone looking to straighten their curls, but with so many options available, choosing the right one can be overwhelming.

Here are some things to keep in mind when choosing the best flat iron for curly hair.

Firstly, consider the plate material. Ceramic or tourmaline plates are ideal for curly hair as they distribute heat evenly, minimizing the risk of heat damage. Titanium plates, on the other hand, are great for thick, coarse curls as they provide a higher heat output.

Secondly, choose a flat iron with adjustable temperature settings. Curly hair requires lower heat settings to avoid damage and breakage. A flat iron with adjustable temperature settings allows you to customize the heat to your hair type and texture.

Thirdly, choose a flat iron with larger plate widths for easier styling. Larger plates allow you to straighten more hair at once, which is especially important for people with thick, curly hair. Lastly, look for added features such as anti-frizz technology and ionic technology.

Anti-frizz technology smooths hair while ionic technology reduces static, leaving hair smooth, shiny and frizz-free.

Choosing the best flat iron for curly hair can be challenging, but with these factors in mind, you can find the right one that will keep your curls looking shiny and healthy.

What Kind Of Straightener Is Best For Curly Hair – Brush Or Flat Iron

If you have curly hair, you know the struggle of finding the perfect straightener. With so many options on the market, it can be overwhelming to decide which kind of straightener is best for your locks. So, what kind of straightener is best for curly hair – brush or flat iron?

Firstly, it’s important to note that brush straighteners are not ideal for curly hair. Brush straighteners are designed to work best on thick, straight hair. They can create a sleek, polished look, but they are less effective and sometimes even damaging when used on curly hair.

On the other hand, flat irons are a better choice for curly hair. Flat irons come in a variety of sizes and materials, but ceramic or tourmaline plates are the best for curly hair. These types of plates provide an even distribution of heat, which is important for curly hair as it needs hotter temperatures to straighten compared to straight hair.

Additionally, flat irons also have the ability to curl the hair. With the right technique, you can create a variety of different styles with a flat iron, from straight and sleek to bouncy curls.

Overall, when it comes to choosing the best straightener for curly hair, a flat iron is the way to go. It provides versatility, efficiency, and safety for your curly locks.

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. 

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.
