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 hair extensions and reduce their 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 the premium hair extensions that you can buy online.

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

While most people think of using heat protectants to curl or straighten their hair, these products can also be used on hair extensions. Using heat styling tools on extensions can deteriorate their quality and cause hair fall-out over time. So, invest in a professional-grade heat protectant to increase the longevity of your extensions. The following buying guide discusses some factors to consider when choosing the best heat protectants for hair extensions.

Things To Look For In A Heat Protectant For Hair Extension

  • Formula And Function: Assess the kind of hair extension you are using before buying a heat protectant. Choose a product that offers thermal and anti-frizz protection for thick hair extensions. Select thermal and volumizing heat protectant if you have a thin hair extension. For curly hair extensions, stick to cream-based formulas that deliver lightweight hold.
  • Type Of Heat Protectant: Heat protectants are oil-based and water-based. If you have oily hair, choose an oil-based protector, while in the case of dry or normal hair, opt for a water-based protector.
  • pH level: Always opt for heat protectants that are pH-balanced. Some products have a high pH level (8+), which is too harsh on your scalp and extension, while other protectants have a low pH level (3), which does not provide enough protection against heat damage. Therefore, ensure that the formula matches your hair’s natural pH level.
  • Degree Of Protection: Styling tools usually work at high temperatures. So buy only a heat protectant that offers protection against higher temperatures from 400 to 1200 degrees Fahrenheit. It is also advisable to use your styling products at low to medium heat settings to reduce damage.
  • Ingredients To Avoid: Steer clear of heat protectants containing alcohol, sulfate, silicones, and water-based polymers. They rob the extension of its shine and deteriorate its texture.
  • Lab-Tested: Only purchase independently lab-tested products as they offer the optimum protection.
