The Importance Of Using Heat Protectants On Your Hair Extensions

The constant use of heat styling tools like curlers, flat irons, and blow dryers can damage and reduce the hair extensions’ lifespan. Heat makes natural or synthetic hair extensions weak and breakable. You can prevent this damage by using a heat protectant.

Heat protectants shield the hair extensions and save them from breakage, shrinkage, and damage. They also help extend the lifespan of extensions, wigs, weaves, and other synthetic hair.

Let’s now look at the top heat protectants for hair extensions that you can buy online.

Note: Heat protectants are flammable. Store them away from electrical and other flammable materials.
