If you love to heat style your hair, you’re no stranger to heat protectant—or, at least, you shouldn’t be. While you may love the big, voluminous curls or sleek, polished locks you achieve with the help of your go-to hot tools, all of that heat styling can take a serious toll on the look and feel of your tresses. That’s why if you want to keep creating the looks you love without dealing with excess dryness, frizz, or breakage, you’ll need to add a heat protectant to your hair care routine ASAP.

While every mane can benefit from a heat protectant, not all formulas are created equal—and you should invest in a product that’s best suited for your hair type and concerns. Below, we’re breaking down what you need to know about heat protectant plus 15 of the best heat protectant formulas you can buy now.

Do hair heat protectants really work?

Much like wearing a mask to protect yourself from germs, heat protectants act as a barrier between your strands and your hot tools. These formulas coat the hair cuticle and minimize the effects of heat damage, help manage frizz, and protect against color fading. It’s important to note that heat protectants don’t protect your hair from damage completely but help to reduce the chance of damage Even if you use heat protectant every time you use hot tools, we recommend taking breaks from heat styling every few days, air drying, and keeping your hot tools on the lowest temperature setting.


Do you let heat protectant dry before straightening?

If you wrap your hair around your curling wand the second after you apply a heat protectant, that sizzling sound may be all too familiar. This is the result of your hot tool coming into contact with the liquid that’s still damp in the hair. That’s why we recommend distributing the product evenly throughout your mane and waiting for it to dry completely before you begin styling.
