Flat Iron for Curly Hair Buying Guide

Best Flat Iron for Curly Hair 2If you notice that your follicles have an oval shape or a shape that doesn’t seem to be flat, the chances are your hair is curly. When choosing hair care products, you want to pick the ones that meet the specific characteristics of your follicles. That also includes the selection of a flat iron.
You shouldn’t worry if you don’t know where to start. It is precisely why we prepared this buying guide. Start reading and learn how to pick a reliable flat iron for curly hair, and get the desired hairstyle every time!

How to Choose Best Flat Iron for Curly Hair

We will dig into the specifics of the flat iron later, but let’s discuss your hair first. Here is a fun fact – curls are hereditary in 90% of the cases. Also, the chances are that people with flat hair envy you for your curls.
The reason why curls appear is that proteins and keratin, which build every follicle of your hair, make disulfide bonds. It is those bonds that cause the hair to have various shapes, including the curly one.
But did you know there are three different types of curls? Your hair might fall into one of these subcategories:

  • Naturally curly hair
  • Wavy curls
  • Kinky curls
  1. What If You Have a Naturally Curly Hair?

    The thing to remember is that hair that is naturally curly is also quite strong. It is why you will need flat irons with a generous amount of heat to straighten and tame them.
    The experts recommend curling irons that go up to 450F of heat. Since you need an extreme level of heat, you might consider titanium flat irons because they can achieve high temperatures fast. However, you also can’t go wrong with ceramics and tourmaline, except you will probably need more time to finish styling.
    Black hair can be even stronger than other types. Please check out our buyer’s guide of flat irons for natural black hair to find an appliance that is the most suitable for your hair type.

  2. How to Tame Kinky Curls

    The name used for this curl type is intriguing, and volume is a trademark of kinky curls. You will also find that these curls are exceptionally strong, which is why they require a high level of heat.
    The experts recommend that you should feel free to go up to 450F. Furthermore, you should even consider keeping your hair in the plates for a bit longer to straighten it properly.
    We would, however, advise you to be careful with high heat. If it is possible to use a bit lower temperature setting than the highest one, go for it as it can reduce potential hair damage.

  3. Should I Use Extremely High Heat for Wavy Curls?

    The third type of curls is “waves.” These may be the softest curls of all three types, which is why the heat you use doesn’t have to be that big.
    The experts still recommend keeping the temperature at around 400F, but if you feel you can achieve the desired results, don’t hesitate to lower the heat. Waves are not that resistant, which increases the chances of achieving the desired results with a fairly low temperature.
    Additionally, using too much heat may cause hair damage, which is not something that you would like to happen. It is something fine hair owners need to be careful with as their hair is particularly sensitive to high heat damage. That is why you should check the reviews of flat irons for fine hair as it contains appliances most suitable for that type of hair.
    Now, as for the desired material, you can’t go wrong with ceramic. Tourmaline can boost heat distribution, which can be helpful to achieve the desired hairstyle quickly.

A List of the Most Important Features and Specifications of a Flat Iron for Curly Hair

Before we proceed, let’s scan the features of a flat iron. These are the parameters that can make a particular unit specific:

  • Plate material – the primary thing you want to consider is the material for the plates and its coating. The most popular choice is ceramic, but you will often find this material in combination with tourmaline. It has the task of promoting even heat distribution and minimizing the damage to your follicles. The final option is titanium, which is the most durable and long-lasting material. It can also be the quickest to heat up.
  • Plate size – you should choose this based on the type of your hair. If it is long, you can feel free to choose a 1 ½-inch or longer plate diameter. But if your hair is short and sensitive, you may want to go with 1-inch plates or smaller.
  • Adjustable heat – some units may have different heat settings to ensure you can optimize the temperature to your hair needs.
  • Control buttons – pay attention to the position of the on/off switch and other control buttons. You want them to be conveniently placed on the handle so that you can easily reach them whenever you need them. Additionally, you shouldn’t be able to hit them accidentally while operating the flat iron.

What Is the Ideal Temperature to Straighten Curly Hair?

Curly hair doesn’t mind high heat, which gives you the freedom to go with flat irons that don’t have adjustable temperature settings. However, if you can choose between different heat levels, it is a feature that you want to use. Additionally, curly hair is usually strong, which is why you shouldn’t consider units that can’t reach at least 400F of heat.
If you are choosing a flat iron for thick hair, you can go with a high temperature of between 400-450F. But if your curls are not that aggressive, and you would describe your hair as fine and sensitive, you may go with a heat level lower than that.
You might need to experiment to see how your hair responds to different temperatures. In that case, always start with the lowest setting you think will work for straightening your hair.

What Other Features Should You Consider When Choosing a Flat Iron?

We mentioned basic features, but you can also look for bells and whistles, and characteristics that may add to the convenience of using the device:

  • Automatic shutdown – the feature will turn off the iron automatically after some time. In most cases, it will be somewhere between 60 and 90 minutes.
  • Brand – a reputable brand is a guarantee that you will receive an original product with all the features as described in the description.
  • Warranty – a generous warranty is a fine indicator that the manufacturer designed a high-quality appliance that can serve you for a long time.
  • Price – you don’t want to neglect considering the price of your flat iron. First, it must meet your budget. Additionally, it needs to provide a fine ratio of cost and quality. In other words, it needs to be a good value for the money.

How to Straighten Curly Hair – A Detailed Guide

choosing flat iron for curly hairYou might know the basics when it comes to how a flat iron operates. However, if you are straightening curly hair, you may need to apply some specific move.

How to Use a Flat Iron on Curly Hair: A Step-by-Step Guide

That is why we prepared a specific step by step guide on straightening curly hair below. And if you want to curl your hair, we also have a best flat iron for curling hair guide that can assist you in the process.

  • Step 1: It All Starts in the Shower

    The first step of straightening curly hair doesn’t even involve using a flat iron. That is because everything starts by washing your hair to prepare it for straightening.
    You probably know that, but go with a conditioner and shampoo suitable for curly hair. The ideal product should work on minimizing frizz, which can be especially important if it is high humidity outside.
    Even if you have thick hair, you should consider using a heat protectant spray. Use a blow dryer or wait for your hair to be completely dry.

  • Step 2: Start from the Root

    Turn on your flat iron, and wait for it to achieve the desired temperature. Depending on the appliance you are using, it may take up to a minute to reach the preferred heat level, so make sure to be patient.
    Now, grab a hair clip or something else you can use to move the upper hair section so that you can reach the root.
    Next, take the first section of your hair between the spot where the curl starts and the root. Use your flat iron to straighten it. You want to go relatively slowly, but also keep your hands steady. The ends of the appliance should face a bit inward.

  • Step 3: Repeat the Process

    The previous step is the entire magic of using a flat iron. The only thing remaining to do now is to repeat that on other sections of the hair.
    Please note that each section should not be too big and fitting for your appliance. Make sure that the flat iron can pass through the entire section right away because you want to avoid making multiple passes. That will increase the risk of damaging your hair, especially if it is not that coarse.
    Also, if it is necessary, modify the section size depending on the location. In other words, pick small sections in areas on the sides and close to the ears, and go with bigger sections where you have more room to maneuver the appliance.


Straightening Tips for Curly Hair

It is time to share some essential tips that will help to straighten your curly hair and make the results last. Here are the factors you want to consider during the process:

  • Only make multiple passes in this case

    – it is vital to avoid making two or more passes at the same hair section. However, you may have missed a small spot, and you noticed that it is still curly. In that case, you can make another quick pass at that part, but make sure not to hold your flat iron for more than a couple of seconds.

  • Think about not using any finishing products

    – while they are recommended for fine hair; strong curly hair might not require any serums or sprays at the end of the process. Furthermore, avoiding to use them may prolong the straightening results. However, this decision is up to you because nobody can deny that finishing products can boost hair quality and volume.

  • Use a hair protectant spray

    – unlike the finishing formulas; you will want to use a protective spray that will improve heat resistance of your hair. It will minimize the damage that flat iron can do. All types of damage are more visible when hair is straight, which is why this additional layer of protection is imperative.

  • Trim your hair regularly

    – while this doesn’t have anything to do with using a flat iron, you should keep in mind that damage like split ends will be more visible if your hair is straight.

Mistakes to Avoid While Straightening Curly Hair

If you want everything to go smoothly, you should stick to the steps and tips we mentioned in the previous to sections. However, if you want to straighten curly hair properly, it is also important not to make any mistakes during the process.
These are the things that may affect the straightening results negatively:

  • Avoid using flat iron on wet hair

    – you may think that it will be easier to straighten it while it is wet, but that is the wrong approach. The only thing you might achieve is a high risk of damaging your hair because it is harder to estimate how long to keep the hair in the plates.

  • You don’t allow your hair to cool down

    – once you finish straightening your hair, it is vital to give it 10-15 minutes to return to its normal temperature before applying finishing products. That way, you minimize the chance of frizz and maximize the potential of any formula that you apply.

  • Using a low-quality curling iron

    – your hair deserves the best possible products and appliances out there. That is why it is vital to pick a high-quality curling iron, and never risk with unknown brands. Remember, it is always better to spend a bit more on a top-quality product that will deliver better results. You can’t put a price on feeling proud and impressing people with how your hair looks!

FAQs & Answers

  • Q: How can I minimize hair frizz?
    A: Frizz is a frequent problem for owners of curly hair that use flat irons. If you want to minimize frizz while straightening your hair, you should make sure that your iron utilizes the ionic technology.

  • Q: How long will my straightening look last?
    A: It depends on your hair specifics. If your curls are not that aggressive, and you would describe them as wavy curls, the effects may last for several days. However, you will have to repeat the process after three or four days.
