How to Choose a Flat Iron

First of all, protection should be your number one priority when straightening natural hair. With this in mind, try to look for straighteners with ceramic blades. Those infused with tourmaline or other minerals will also help to reduce frizz while sealing the cuticle and locking in the moisture. It will help to prevent heat damage and stop your hair from dehydrating.

Secondly, consider your hair type. If you have thinner hair, you will need to ensure your flat iron works well at lower temperatures. Equally, those with more coarse hair will need a flat iron that reaches higher temperatures. Variable temperature settings will enable you to create more versatile styles.

If you are looking to straighten a full head of thick hair, you will probably be looking for a wider blade. Shorter hair will need a thinner blade whereas longer hair will benefit from a wider blade as it cuts down the time it takes to straighten. However, if you also want to use this tool to curl your hair, then you won’t want anything wider than 1-inch.

Try to look for some easy-to-use functions such as a lightweight flat iron with a swivel cord. Equally, make sure the cord is long enough not to be restricting. Some flat irons come with heat resistant gloves, heat-proof mats, and safety stands. These are all great added features.

Types of Flat Irons

Your hair type can dictate the best model of flat iron for you. Some flat irons work better on certain hair types than others.  

Ceramic flat irons are the most versatile, and you can use them with most hair types, from thin hair to curly, coarse hair. They heat evenly and can work at low and high temperatures. They tend to be the most protective as the evenly distributed heat prevents direct heat spots from occurring, which can burn the hair.Moreover, most ceramic flat irons tend to come with ionic technology, that helps to neutralize damaging positive ions that cause the hair to break and frizz. No matter your natural hair type, you’ll find good results when using a ceramic flat iron.

Titanium flat irons heat up very quickly and at a very high temperature. While they are extremely effective on natural hair, especially coarse, curly hair, they can be damaging. They do not heat as evenly as ceramic flat irons and can develop hot spots. However, if you straighten your hair daily, it is heat trained. Regarding this, it will be able to withstand much higher heats without getting damaged. If this is you, a titanium flat iron will give you great results.

If you have frizzy hair, choosing a flat iron with tourmaline technology will be a rewarding experience. The tourmaline helps to reduce frizz by sealing moisture into the hair and producing negative ions that neutralize the positive ions that liberated in the heating process. Tourmaline will help you get a sleeker finish.

Tips and Tricks to Flat Ironing Natural Hair


Separate the hair into parts and deal with one at a time. It will make you straighten all the hair evenly without missing parts.


Make sure you use some form of thermal protectant before straightening your hair. Every time you put heat to your hair, it causes damage, so protecting it with a thermal spray or serum will help to lock in moisture and reduce brittleness.

Start Low 

Always start at the lowest temperature and move upwards. You want to straighten it on the lowest temperature as it  gets better results and reduces heat damage.

Make Sure it’s Dry 

Never straighten your hair wet. This causes the moisture in the hair to burst out of the strands, shattering them. This causes brittleness and breakage. Make sure your hair is bone dry before putting a flat iron to it.

To The Bottom 

Always start at the root and work down to the tip. Try to limit the amount of time the iron is on the tip of the hair as this part gets damaged more easily.

Don’t Blow Dry

Air drying the hair is much better for it in terms of protection. However, braiding it or setting it on rollers will stretch it slightly, making it easier to straighten.


Choosing the right flat iron for your natural hair will help you keep it in good condition and will limit the damage caused. Always consider your own hair type and test the flat iron out at the lowest temperature before cranking up the heat. Make sure to research flat irons before jumping to a choice; understanding other people’s opinions will help you know what works best for your styling needs.
