How to Choose the Best Straightener / Flat Iron for Curly Hair

Considering that everyone is unique and has their own style that varies in thickness, length, waviness, and volume, there are a variety of different straighteners out there for different kinds of hairstyles. A few things to keep in mind when you’re choosing the best flat iron for thick curly hair are material, temperature control, and available features.

It’s important to choose a straightener that’s made of high-quality material and is smooth enough to glide through your locks. Considering that curlier hair may be more difficult to straighten, it’s will require hotter temperatures. You should choose a flat iron with adjustable heat control that´s within your range, which would ideally be between 350 and 450 degrees for thick and curly hair.

Two popular options are titanium and ceramic. Titanium is known for heating up fast and to very high temperatures, which makes it one of the best flat irons for curly frizzy hair. While ceramic straighteners also tend to heat up fast, they don’t typically reach temperatures that are as high as titanium. They are, however, safer to use, so you may want to opt for a ceramic straightener if you have hair that’s thin or damaged from heat or dye. In this case, you should make sure that your iron is made of 100% ceramic and not just coated in the material over a harsh metal. Keep in mind that ceramic straighteners have even distribution throughout the plates, while titanium irons have colder spots and therefore may require constant reapplication and therefore take longer when straightening out your hair.

Many good straighteners for curly hair also use anti-static technology to prevent frizz. Tourmaline is a material that emits negative ions, which have been found to reduce frizz and static while locking in moisture and operating at a lower temperature to further reduce damage.

Straighteners come with a variety of different features. You should figure out which qualities are most important for you and then start your search accordingly. A few beneficial features may include automatic shutoff in case you forget to turn off your iron, a digital temperature screen display, lightweight, a flexible swivel cord, and a fast heat up time. You should also check for indicator lights that tell you whether your iron is on or off.

Also keep in mind that the wider the hot plates are, the more surface area your straightener will cover. Investing in an iron with wide plates will make the getting ready process faster if you have long or thick hair. Choose one that ranges between one-and-a-half and two inches wide and you will find yourself saving time by being able to straighten more hair with every go. However, if you want to be able to iron hard-to-reach areas or have thin or short hair, then a thinner iron may work well for you as long as your hair is not overly-curly.

Our Top Tips For Using Your New Hair Straightener for Your Curly Hair

Now that you’ve found the best straightener for curly hair, there are a few tips that we would like to share with you. Considering that flat irons do emit a considerable amount of heat that can cause dryness and split ends, there are some steps that you can take in limiting damage and enhancing your overall look.

First and foremost, you should invest in a thermal heat protectant spray that acts as a medium between your hair and your hair straightener. It works by using silicone to create a protective layer over strands to trap moisture and strengthen hair, protecting your strands from intense heat. They can also help condition your hair and make it dry faster. Spray it on prior to using your new tool.

Make sure you brush your hair thoroughly to get rid of knots and tangles before you start using a flat iron. This will make it easier for your strands to glide through your straightener, and as a result, your hair will look more neat and polished. You should also blow dry your hair or wait for it to dry before you begin the straightening process. While there are wet-to-dry irons that use steam technology to simultaneously blow dry and straighten your hair, these shouldn’t be used right after you get out of the shower. They should only be used once your hair is damp or dry, as styling soaking wet hair even with the best hair straighteners for thick curly hair can cause excessive damage, frying your strands and creating split ends.

While straightening your hair, you should always monitor your temperature and make sure that it’s not too hot, yet uses enough heat to make your curly hair straight. Divide your hair into sections and straighten them separately, starting with the back of your head and working your way towards the front. Clip your parts into different one-inch sections and take your time to iron each one slowly if you want a beautiful, long-lasting finish.


Alternate Uses For Your Hair Straightener for Your Curly Hair

Contrary to popular belief, the best flat irons for curly hair are not limited to straightening. They can also be used to enhance your curls, crimp your hair, and create different kinds of waves. The straighteners that are curved or rounded are the best for forming different styles of waves and curves. Many also come with 360° swivel cords that allow flexibility in movement and make styling your hair easier. Some models are even wet-to-dry and use steam technology to dry damp hair faster than a blow-dryer can. You can also use the heat to iron your clothes, smoothing out wrinkles.


Cleaning and Caring For Your New Hair Straightener

Different materials require different amounts of care and attention. Ceramic is delicate and may crack when dropped and stop working after a period of time. Titanium, although lighter in weight, is more solid and likely to withstand damage which makes it more durable. Regardless of whatever iron you buy, now that you’ve got one of the best hair straighteners for curly hair, you wouldn’t want anything to happen to it. There are a couple of things you can keep in mind to prolong the life of your iron and use it for as long as you can:

It may be a good idea to store your iron away when it’s not in use. You can place it in your bathroom cupboard to avoid buildup of dust and lower the chances of accidentally knocking it over if it’s just lying on the counter.

It is highly recommended that you regularly clean your flat iron to get rid of unwanted residue from styling products and heat protectant sprays. Once you’ve managed to successfully tame those curls, unplug your straightener and wait for it to cool down. You can either use a professional cleaning spray, rubbing alcohol and cotton swabs, or warm water and a paper towel to scrub the plates. Repeat this process at least once a month or after every use if you regularly use your flat iron.


Final Word

With advancements in technology and style, the best straighteners for thick curly hair nowadays are more advanced, compact, lightweight, convenient, and powerful than ever. There are many brands out there that sell high-quality irons and make straightening curly hair, no matter how thick and seemingly uncontrollable it may be, feel like a piece of cake.
