Best Flat Iron for Curly Hair Guide

Fighting with curly hair can be exhausting, and it can be challenging to find the right tools to tame your mane. Every curl is different, and depending on your hair density, your ideal flat iron may look different than mine. As someone with curly hair, I know how overwhelming it can be to search for the perfect flat iron that doesn’t leave behind any stray waves.

The best flat irons for curly hair will actually smooth out your hair without causing major damage. The highest quality flat iron is likely to cause the least amount of breakage.

In this list, we have chosen the favorite flat irons of salon professionals with high-quality heat distribution between the plates, various plate sizes to fit every need, and a mix of the two best materials for flat irons: ceramic and titanium.

What to Look For in a Flat Iron

With so many flat irons on the market, how do you know which is the best for curly hair? There are a few features that you want to keep in mind.

Adjustable Heat Setting

Temperature control is also a must-have feature. Most flat irons come equipped with temperature control, but it varies in precision. It’s also a good sign that the heat will be evenly distributed without hotspots and minimize heat damage.

Plate Size

Decide which size plates will work best for your hair. If you have really thick curls, you may want to consider a wider plate width, and if you have fine hair, it can speed up the time it takes to do your hair.

Titanium vs. Ceramic

Consider the composition of the plates. Are they completely ceramic, have tourmaline, or are they titanium plates? Different hair density does better with different materials. Thick hair can withstand the intense heat from titanium plates, but it can cause breakage and damage to fine hair.

It may seem like there is a lot to consider when comparing flat irons, but this guide will walk you through the best flat iron options to help smooth out your curls.

Question: Which is better: titanium or ceramic plates?

Answer: Your hair type is the guiding factor in this decision. If you have fine curls that are easier to straighten, go for a ceramic flat iron. If your curls are thick or coarse, the heat capabilities of the titanium flat iron will work best.

Question: Is it okay to straighten your hair every day?

Answer: Heat damage is a genuine concern when heat styling. It is perfectly fine to straighten your hair often; just be sure to take proper precautions. To avoid drying out your hair, use a heat protectant before you apply heat to your hair. It can help limit breakage or premature damage. You can also use a leave-in product after you flat iron your hair to preserve the style so it lasts multiple days without a need for touch-ups.

Question: Should I get a 1-inch or 1.5-inch flat iron?

Answer: The size of flat iron you choose largely depends on your hair’s length and density. The longer or thicker your hair, the easier it is to get away with a wider flat iron. If you have short hair, bangs, or lots of flyaways to tame, you lose out on precision with wider plates.

Question: How can I tell if I need a new flat iron?

Answer: The best indication that you need a new flat iron is the deterioration of the plates. If the plates are visibly worn down, scratched, or lifting from the iron entirely, you know it’s time to invest in new flat iron.

Final Thoughts

Not all flat irons are universal. Factors such as your hair thickness, length, and curl density, will be a driving force in which flat iron you choose.

CHI is a tried and true brand and has been my personal favorite since I bought one as my first ever flat iron. If you don’t want to spend that much, the Kipozi Professional flat iron also has titanium plates at a much more affordable price. If you’re leaning toward a ceramic option, the HSI Professional flat iron is a bestseller and favorite among the curly-haired crowd.

However, all the flat irons mentioned on this list are great options. There are a variety of reputable brands with some different features that you can look at to see what’s most important to you. There are some affordable options and some high-end flat irons if you’re looking to splurge.

Ultimately, you should consider how often you’re going to use your flat iron. If it’s a tool that’s in your arsenal every day, then the higher quality and more expensive options tend to be gentler on your hair in the long term.
