In our good year of 2021, it seems curly hair is finally receiving the praise it deserves. But that doesn't mean those with ringlets and coils can't still experiment with heat styling. After all, there's something liberating about the ability to transform your texture at will.   

Finding a great straightener for curly hair is a journey in and of itself. Like snowflakes, every curl pattern is unique, and a tool that works well for one curly-haired person might not cut it for another. To help you determine what type of flat iron will effectively (and safely) straighten your mane, we've broken down the nitty-gritty, from material composition to recommended temperatures and heat protectants. 

Titanium vs. Ceramic: What's the Difference?

As Ulta notes in its Hair Tool Guide, titanium flat irons distribute intense heat quickly and evenly. That makes them a great choice for thick, textured hair, and they tend to be the preferred option among professionals. 

If you have fine or damaged hair, however, the high heat of a titanium straightener could cause breakage and dryness. That's where ceramic comes in. Flat irons with these non-metallic plates produce negative ions that seal the hair cuticle, which results in a smooth, healthy-looking finish. Many ceramic straighteners are also infused with tourmaline, a mineral that maximizes the output of negative ions. 

What Temperature Should Your Straightener Be?

The temperature you choose for your straightener should be a fairly intuitive decision. Finer hair requires a lower heat setting to prevent damage, while coarse strands can safely withstand higher temperatures. According to Ulta, fine or chemically treated hair should be ironed below 300 degrees Fahrenheit. Meanwhile, medium-textured hair can handle between 300 and 380 degrees, and tighter textures may require up to 450 degrees to achieve the desired pin-straight look.  

How to Protect Curly Hair While Straightening

Two words: Heat protectant. A quality protective oil or spray can mean the difference between retaining your natural curl pattern and creating severe long-term damage. Some products work more effectively on dry hair, while others should be applied to damp or wet strands. No matter which you choose, keeping your straightener below the product's maximum protectant temperature will ensure it functions properly. For example, if a spray protects against heat up to 350 degrees, you shouldn't exceed that number when styling.   

With these factors in mind, we scoured the internet for the best straighteners for every curl pattern. We ended up with 15 high-quality flat irons that have received the approval of curly-haired customers from all over the country. 

According to reviews, these are the best straighteners for curly hair:
