How to Use A Thermal Protectant for Your Hair

It is always best to apply some kind of thermal protectant to your hair before using any kind of thermal styling tool. Before blow drying, you should apply a light heat protectant oil to the ends of your hair to prevent split ends. If you are using a flat iron or a curling iron or wand, it is best to apply a heat protecting spray that has a little hold in it.

In these instances, even a lightweight hold hairspray will work fine but we recommend using a spray that was designed to protect your hair from heat.

It is important to keep in mind that thermal protectants only help to prevent hair damage. You still have to make sure that you do not leave your hair in the clamp of your flat iron or curling iron or wand for too long. Let’s take a look at some of our favorite thermal protectants.
