September 2, 2022 by Edna K. Martin – Hairstylist, Certified Skin Care Coach

Flat irons are one of the most versatile styling tools a woman can have. Its work ranges from straightening to curling your mane. However, when using hot tools such as flat irons, you need to consider some things.

For instance, you should always apply heat protectants before using a flat iron. But, using heat protectants does not mean that the flat iron temperature should be high.

Thanks to quality flat irons with adjustable temperature settings, you can now set the temperature of your flat iron according to your preference. This leads to the question of what the ideal flat iron temperature is.

If you have this question in your mind, you have come to the right place. Read on to know the flat iron temperature guide for different flat irons.

Factors that determine your flat iron temperature

Before you know the temperature setting, you will be opting for your flat iron. You should know that there are some things you have to know first.

Here we will discuss the factors that determine your flat iron temperature.

Hair type:

Before embarking on any hair care routine, you should first and foremost know your hair type. Knowing your hair type means you will know the right products and the right way to care for your lock.

There are different hair types ranging from normal to fine to coarse. Hence, your hair type determines the heat you will expose it to.

Condition of your hair:

The next factor to consider is the condition of your hair. Now that you know your hair type, you should know the condition of your mane.

For instance, if your hair is unprocessed, the temperature it needs is different from when flat ironing processed hair. Thus, treated hair is more fragile.

Yet, if your mane is untreated, you might need to know whether the hair is dry or not. Dry hair is at the risk of heat damage, so you should be cautious of the flat iron temperature.

Also, it is essential to know whether your hair is damaged. If you expose too much heat to a damaged mane, it is at the risk of more damage. So, you need to be cautious with the temperature settings.

Generally, hair that is in healthy condition can withstand more heat than unhealthy main. Yet, you should be careful of the temperature settings.

Quality of the flat iron:

every woman should see flat iron as an investment. Hence, you should go for a high-quality flat iron. This ensures that you can use the tool without much damage to your mane.

One of the features of a quality hair straightener is adjustable temperature settings. If the flat iron you have does not have adjustable temperature settings, you should consider going for one that has it.

The heat protectant you are using:

This is another thing you should consider. Different thermal protectant products have different ranges of temperatures. For instance, if the heat protectant you are using has 300°F, your flat iron temperature should not be higher than that.

These four factors are essential when determining the temperature range you need. That being said, let us go into the flat iron temperature guide.
