How To Choose A Good Flat Iron for Relaxed Hair?

Flat Iron Materials

They also glide through the hair without snagging and release negative ions that seal in moisture into your hair.

Temperature Control

This is the most important feature to consider when choosing a flat iron. This is because different hair textures require a different amount of heat.

Relaxed hair is the most fragile hair, and you need a flat iron that you can control the temperature while styling. Intense heating causes smooth results but in return leads to heat damage that can interfere with your curl pattern.

Being in control of the heat will prevent any irreversible damage to your hair. Go for a flat iron with multiple heat settings.


Tourmaline flat irons are also good for relaxed hair because they produce six times more negative ions compared to ceramic. Your hair becomes shinier and silkier with less heat.

Size of the Plates

You can choose the size and width of your flat iron plates depending on your hair type. If your hair is long and coarse, you require a flat iron with wider plates so that you can style your hair faster. If your hair is thin and fragile, smaller plates will do.

Frequently Asked Questions

What temperature is best to flat iron relaxed hair?

This depends on your hair type. If your hair is colored, fragile, thin, and delicate, subjecting it to high heat can lead to damage. Use low or medium heat for such hair. On the other hand, if your hair is coarse and thick, you need to use the highest heat setting.

Is titanium or ceramic better for relaxed hair?

Titanium is the best if your hair can take up the heat because it heats up in seconds and can be damaging to fragile and thin hair. Ceramic is gentler and good for thin and delicate hair.

How often should you flat iron relaxed hair?

Once a week


Relaxed hair is very fragile and requires the use of proper hair tools to protect it from thermal damage and breakage.
