How To Choose The Right Flat Iron for Thick Hair?
It goes without saying, ceramic plates will protect the delicate strands of your hair better. These plates are much gentler and distribute heat evenly across the hair. Thick hair, this is what will help to speed up the hair straightening process.
Where possible look for hair straighteners that have this type of metal plate. They heat up quicker also and remain hot for longer. Watch out for flat irons that claim to be ceramic.
Some will state ‘ceramic coating,’ which means they are not ceramic; they have the coating. The quality will not be the same as a fully ceramic plate. This will mean more damage and overall lower performance of the device.
However, they are a lot cheaper and these disadvantages are the reason why.
The coating is prone to remove itself over the lifetime of your flat irons; keep this in mind. With thick hair, the best option is to look for a device with wider plates, not necessarily longer. This will help with two things.
Firstly, speed and how long it will take you to straighten your thick hair. Second, wider plates will mean that you spend less time swiping the plates up and down your hair, resulting in less heat damage.

Quick Styling- Wet To Dry
More recently these kinds of flat irons have entered the market. Of course, they will save you time as there is no need to use a hair dryer on your hair first.
However, with very thick hair, think about how practical this option is for you. Your hair’s thickness will mean that extra heat and drying are needed. As much as a pain it may be to have to use a hairdryer first, for you as a woman with thick hair, this is advantageous.
Using a wet-to-dry flat iron may mean longer styling and possibly a bit more heat damage if you pull the plates through your hair, more than what you normally would as it’s still wet.
If your hair is thick, consider opting for a flat iron with smaller or narrower plates on the shorter side. The smaller size plates could help you get closer to your roots and be easier to handle while straightening your hair.
As an option, it is an advantage to you with thick curly or wavy hair if you can control the heat settings on your flat iron. Also, think about the level of heat you want your flat iron to reach.
Will it be hot enough for quick results and less swiping? Is it a question you should ask yourself while deciding what type of flat iron to buy?
The higher the heat, the less time should be spent swiping up and down your hair. Add this in with a thicker width plate; you are in heaven! Also, think about the type of thick hair you have; if you have African- American hair again, the heat control level will be of excellent value.
How To Use Flat Iron On Thick Hair?

When you apply whatever to the hair, you must ensure that the hair is dry before applying the flat iron to straighten it. The benefit of drying that hair is that it makes it healthy and it does not much time to straighten it with flat irons.
If you think that heat can damage the hair then you can use a heat protectant. The type of heat depends on the type of flat irons you use. This is in the form of lotion and sprays.
If you have thick hair this is good for you. You can then apply the iron to the hair and do it gently and you can gradually adjust the temperature until you achieve the kind of results you want to achieve.

Flat Irons for Thick Hair FAQs
Basis this on the type of hair you have, if you have very thick long coarse hair, for you I would suggest wider plates, to help with the thickness of your hair to straighten as a priority.
Ceramic plates allow for even distribution of heat, this is important as it means less time will be spent ironing over areas that are not straight enough. It will also reduce heat damage as not all the heat will be concentrated on one area of your hair.
Some devices have a ceramic coating this is what makes them cheaper and more affordable. Be careful, please! As the coating can chip and peel. This will expose your hair to damage and burning.

Titanium plates heat up very quickly and will transfer the heat a lot faster than ceramic plates. That said when using this kind of plate, you are more open to burns, because of the high level of heat that is transferred and retained against the hair. The advantage is they will work quickly.
Tourmaline is a mineral that is crushed and added to the metal of the plates of a flat iron when it is produced. It helps to give hair a healthy shine.
A heat protector always, it can be a spray, lotion or balm this is your choice, as long as the primary focus of the product is to protect the hair from damage. A leave-in condition is also recommended.
Stay away from oils as this can burn under the heat, and cause damage to your flat iron in the long term with the product built up and burned onto the device.
Sadly, there is a chance yes! But make sure you use a heat protection product, also limit the time you spend swiping your hair with the irons if you can. Keep an eye on the level of heat you use also.
Of course, you can! You can use it to add volume and create soft waves in your hair. Just curl your hair around the flat iron instead of swiping it straight at the ends to create waves.
Overall when it comes to flat irons suitable for thick curly or coarse hair, it appears that ceramic plates, different heat options, and wider plates are the best options to look out for.
You can’t go wrong; there will be a suitable setting for everyone.
The wide plates make dealing with thicker hair much easier to manage and faster to straighten.
You could also keep in mind that universal usage is a good option to have from a flat iron. This will mean you will not need to reinvest in a new one if you travel.
