Curls are awesome! Ringlets, corkscrew curls, beachy waves, and afro hair should all be celebrated. But if you have curly hair, you will know better than anyone that curls can be hard to maintain. They can tangle easily, become frizzy and be difficult to style. And sure, the volume is great.
But sometimes it can be a bit too much. So it can be tempting to turn to heat styling tools and flat iron your hair into submission sometimes. It can help you achieve a straight, sleek look, get more easy styling, and hey, sometimes it’s just fun to change it up.
So you are on the market for a flat iron. But which hair straightener is best on curly locks? There are lots of different features to choose from which can be overwhelming. Should you get a ceramic or titanium-plated device? What is bio ionic or negative ion technology? What temperature do you need for best results? And how much should you expect to spend? Well, the above questions may depend upon your needs and hair type.
Metal-plated tools conduct heat better and heat up faster meaning they are often preferable for people with very curly hair that is hard to straighten. Ceramic plates heat up more evenly however and may provide more consistent results. You may especially consider these if your hair is a normal type, and not too curly or hard to straighten. Check out tourmaline plates and tools with negative ion technology if you suffer with much frizz or static.
Frizz and static are caused by positive ions and so the negative ones help to neutralize them. Flat iron temperatures usually reach up to 450 degrees Fahrenheit. The hotter the plates, the more effective they will be on your hair, but also the more likely they are to cause damage.
To avoid heat damage, it is best to use the lowest possible heat that will work on your hair. So it is best to experiment with care, make sure you use heat protector and take proper care of your hair before and after applying heat.
So, without further ado let us introduce the list of our top 10 favourite flat irons for curly hair. We know there is a lot of choice out there, so we have made things easier for you by reviewing 10 for you. Take a look below and you will find the best straightener for you in no time.

Which are the best hair straighteners for curly hair?
Finding the best flat iron for curly hair can depend on your exact hair type and your needs and preferences. Like if your curly hair is very coarse, you will likely need a tool that reaches higher temperatures than someone with very fine curls. When choosing the best hair straightener for you, look at the plate material and size.
Metal-plated tools (like these titanium straighteners) heat up faster and might be more suited to very curly, coarse hair, while ceramic ones heat up more evenly and could be more suited to finer hair. If you want quicker straightening with a tool that can handle large volumes, consider a 1.75 or 2 inch plate. If you would like versatility to curl and style with your straightener, we would recommend a 1-inch design.
Finally consider factors like price, size, and ease of use to make your decision. Take a look at the list above for some of the best hair straightener choices on the market for curls.
Is hair straightening good for curly hair?
In general using excessive heat on your hair in any form can be damaging and drying to the hair. This goes for curly and straight hair alike. But don’t worry! This doesn’t mean you shouldn’t straighten your hair. As long as you take the correct precautions, like using heat protector, taking breaks between straightening days, and using the lowest heat possible for your hair, it is perfectly healthy to do so.
In fact if you have very tight curls or knotty hair, straightening can be a benefit. This is because it can help with things like reducing knots and tangling, and therefore reduce hair breakage and loss. If you already have particularly delicate or damaged hair, you may be more susceptible to further damage from straightening.
How to flat iron curly hair?
To get the best results when using a flat iron on curly hair, start by dividing your hair into small sections. It can be best to clip up your upper layers of hair and work your way up from the under layers.
Once you have a small section, comb it out from the tips first to remove knots. Add heat protector and grab hair in the iron from as close to the root as possible. Pull device over your hair and voila! Now move on to a new piece until entire head is covered.
So there you have it. Our top 10 flat irons for curly hair. Although we celebrate every hair type, we think it is fun to change things up and keep it fresh. And we are advocates of people doing whatever makes them feel good! So whether you want to rock curly or straight tresses tomorrow, now you have the tools to go for it!
