Buying Guide: Find The Right Flat Iron for Curly Hair!
You may be wondering why curly hair is so tough to straighten. The reason for that is curly hair is usually thicker and coarser than straight or wavy hair. Along with being thicker or denser, that also means it has strong protein bonds that are harder to break down so your hair will straighten. These are the very reasons why not just any flat iron has the ability to safely straighten curly hair.
So what should you look for in a straightener to use on your curly hair?
Here is a list of some of the main features to look for on a flat iron so you will be satisfied with it when you go to use it on your curly hair:
- Multiple temperature settings
Whenever you are straightening your curly hair the more options you have for doing that the better. One of the things it’s nice to have multiple options with is your flat iron’s heat settings. The more you have the more likely you are to find a heat setting you really like to use when straightening your hair.
We mentioned that curly hair is usually thick and coarse. One thing to note is that word ‘usually’ has some play in it. That is because not everyone has curly hair that is thick or coarse. That also means that not everyone has curly hair that needs extreme high heat to straighten it. That is why it’s preferred to have a variety of heat settings on your flat iron.
Here are some rough guidelines as far as the temperature that usually works best at straightening different types of curly hair:
- Fine or thin hair: 230ºF – 340ºF
- Medium or normal hair: 310ºF – 390ºF
- Thick or coarse hair: 360ºF – 455ºF
Keep in mind this is just a rough guideline that works for most people. To be on the safe side, always start out at the lowest heat setting in the suggested straightening heat range for your curly hair type. Work your way slowly in the heat range until you find a setting that straightens your curly hair easily and does not damage it in the process.
- Specialty plate coatings and infusions
You will have to do much looking online and in person these days to find a flat iron that does not have some type of coating or infusion on its heat plates. Even the least expensive flat irons will usually have some type of heat plate coating. These coatings and infusions all have special properties that help the curly hair straightening process:
Here is a list of some of the more popular heat plate coatings and infusions you will find and how they help you straighten your curly hair:
- Ceramic plate coating
When have a ceramic coating on your heat plate you are pretty much guaranteeing yourself that your flat iron will heat fast and heat evenly. You certainly don’t want any hair damaging hotspots and that is why ceramic heat plate coatings are so widely used.
- Titanium plate coating or infusion
If you are one of those people that seems to always be in a rush to get ready in the morning than straightening your curly hair with a flat iron with titanium infused heat plates is the way for you to go. Flat irons with heat plates that have titanium infusion are usually ready to use in a matter of seconds.
- Tourmaline crystal plate infusion
It’s all about creating negative ions with this type of heat plate infusion. These negative ions work in a way that helps your hair retain more moisture as its being straightened by high heat. It will also leave your hair with more shine and help eliminate frizz, split ends and flyaway hair caused by static electricity.
- Nano heat plate infusion
This type of heat plate infusion does all the same things as tourmaline heat plate infusion does but in a supercharged way. It’s technology that is said to help your hair retain 25% – 50% more moisture that tourmaline crystal infusion does. Your hair will be much shinier after you straighten it with Nano infused heat plates also.
- Silk heat plate infusion
The smoother your flat iron heat plates are the better. That is where silk heat plate infusion comes into play. Silk infused heat plates are among the smoothest you will find on any flat iron. This cuts down on hair drag and allows you to straighten your curly hair much faster.
Keep in mind that many of these straightening iron heat plate infusions and coatings are used in conjunction with others. That’s ok and it’s actually preferred. There is really no evidence that says a flat iron will not work well if it has many different heat coatings and infusions. So if you can get a flat iron with multiple heat plate coatings and infusions go ahead and do it.
- Ceramic plate coating
- Heat plate width
You will find few aspects of the curly hair straightening process that are more often overlooked than the width of the plate size on a flat iron. That is because it’s a lot more important than people give it credit for. Here is how the different size heat plate widths can aid you during your curly hair straightening process.
- Less than 1” width plate sizes
Smaller size heat plate widths do a much better job at straightening short curly hair than do larger size ones. They enable you to get in closer to the scalp and tend to be more maneuverable overall which is essential to short curly hair straightening.
- 1” to 1 ¼” width flat iron plates
These are widely considered to be the most popular heat plate widths on a flat iron. That is because these size flat iron widths can handle most long and short curly hair straightening needs. Using a straightening iron with these heat plate widths will usually allow you to turn your curls into gentle waves or reshape your natural curls too.
- greater than 1 ¼” width plates
This should be your choice if you have long to medium length curly hair. It’s all about heat plate surface area when straightening those hair lengths and wider heat plates give you that.
- Less than 1” width plate sizes
- Floating heat plate design
Floating heat plates have really changed hair straightening irons for the better. They help your hair stay in contact with the hot heat plates longer as your hair passes through the flat iron. The longer a strand of curly hair absorbs heat the easier it is to straighten. Floating heat plates cut down on both the time and effort it takes to straighten your curly hair.
Holding a heavy flat iron will tire you out much faster than you think as you straighten hair. This is especially true for professional stylists that use flat irons many times throughout their workday. So when shopping pay particular attention to the weight of any flat iron you are thinking about purchasing. Super lightweight straightening irons usually weigh less than 1 pound and acceptable weight flat irons run under 1 ½ pounds.
- Ease of Use
You certainly want your straightening iron to be easy to use also. There are certain things built into a flat iron that really help with this. When out shopping for a new flat iron look for things such as digital temp setting and long power cords with swivel ends that make them easier to use. Ultra-smooth heat plate surfaces will help you straighten your hair faster too.
Helpful Tips for Straightening Your Curly Hair
Here is some good advice on how to get the best results when straightening your curly hair with a flat iron:
- Always prep your hair properly before straightening it – this includes shampooing it (best done the night before) and then making sure you pat it dry. Your curly hair should have very little dampness to it (85% – 95% dry) before starting the straightening process.
- Treat your curly hair with protective serums or oil – heat is your curly hair’s friend when it comes to straightening it but it’s an enemy to your hair’s health. That is why it’s recommended to put on a thin layer of heat protective serum or protective oil like argan oil before you straighten your hair. Ask your professional stylist what they would recommend you use for this step.
- Comb your hair thoroughly before straightening it – one of the keys to getting your hair to straighten easily as you use a flat iron on it is its ability to pass smoothly over the hot heat plates. Getting out all the tangles and knots in your hair will really help your hair pass easily over the hot heat plates.
- Section your hair before straightening it – the next time you are in a hair salon watch closely if one of the stylists is straightening a client’s hair. You will notice they always section it beforehand. This is a time-tested method to help any hair straightening process turn out looking better.
Curly Hair Flat Iron Use FAQ’s
- Question: I just bought a new flat iron and have not used it yet. Any suggestions before I use it the first time?
Answer: I have two big suggestions for you. The first is to thoroughly read through your owner’s manual and instructions before using it. This is because even if you are an experienced flat iron user your new flat iron may work totally different than your previous one.
Be careful using a very high heat setting initially too. Just because you straightened your hair easily without damaging it at 390ºF with your old flat iron does not mean that will work with your new flat iron. Start out with a lower heat setting to make sure you don’t damage your curly hair. You can adjust the heat upward as necessary until you find a heat setting that works great and is easy on your curly hair too.
- Question: Do flat irons have to ever be cleaned?
Answer: Great question and the answer is yes. As a matter of fact, one of the main reasons any flat iron stops performing well is the fact that it has started to build up unwanted residue on its heat plates. This keeps your hair from flowing smoothly across them which is a vital part of any hair straightening process.
How do you clean your flat iron? There are actually several different ways you can accomplish this. One of the best ways is to simply wipe the heat plates down with a soft cloth after you use it (be careful not to do this if the heat plates are still very hot).
For cases where you are starting to get some residue build-up try this. Once the heater plates have cooled completely grab a few soft cotton balls. Next, dip them in rubbing alcohol and swab the plates clean. Once that is done a finished wipe with a soft cloth should leave your heat plates looking shiny and new.
