Keep your hair healthy while using hot tools.

Use your blow dryers, flat irons, and curling wands—I’m not here to judge, I use them too. But if we’re going to town with 300+ degrees, we need to do so with hair drenched in one of the best heat protectant sprays. “I like to think of heat protecting sprays like sunscreen for your hair cuticle,” says celebrity hairstylist Sunnie Brook. “They create a protective barrier between your strands and heat tools, while locking in moisture and slowing down the penetration of the heat.”

They're not going to prevent damage completely. Still, they will ensure you have less breakage, fewer split ends, less frizz, and stronger, more resilient strands, explains stylist Lacy Redway, who works with stars including Tyla, Coco Gauff, and Florence Pugh. Some products, like the Kim Kardashian-approved ColorWow Dream Coat, will even impart a glossy finish.

With healthy hair as the overarching M.O., I set out to find the most protective, cuticle-friendly heat protectants in existence. I’ve tested my fair share, consulted the pros, and asked fellow Marie Claire editors weigh in on their go-tos. To see which hair products made the cut, keep scrolling. And remember: Extreme heat damage is optional, as long as you have one of these heat protection products.

Do I Need Heat Protectant?

Whether it's a heat protectant or a leave-in with UV protection, it's important to use at least one product between your natural hair and a hot tool. “Heat protecting sprays minimize damage from heat—they don’t eliminate damage,” explains Brook. Heat protectant products create a border between your hair and hot tools, which in turn, minimizes damage.

"They help to maintain healthy hair, preventing frizz and completing the finish look. Some heat protectants can also guard against humidity and pollution," explains celebrity hairstylist Davontae Washington, who has worked with Kim Kardashian and Megan Thee Stallion. "It is the same concept as applying SPF before you go out into the sun. Heat protectants should be viewed as a preventative product to minimize damage over time."

What to Look For in Heat Protectants

  • Type of Mist 

Most heat protection products will work for all hair types, but some nozzles are better suited for thick versus fine hair. “If you have thick, curly hair use a spray bottle that covers more area when used,” says Brook. “If you have fine hair, use a product that has a fine mist spray so that you don’t over saturate your hair with the product.”

  • Directions

Pay extra close attention to the instructions on your heat protectant. Some are designed to be used exclusively on damp hair, in which case they’re only suited for people who heat style their hair once per wash. Otherwise, you need to search for a product that can be used on dry hair. “The way you should apply your heat protectant depends on the formula of it, so I recommend following the instructions on the package,” emphasizes Redway. “If it calls to be used on damp hair before blow drying, do so! If it’s an aerosol and can be used on dry hair, apply it as you work on styling your hair.”

  • Additional Ingredients

“Heat protection is designed to work across all hair types, but some have built-in benefits that may be better for your hair type, like moisturizing properties,” says Redway. “If you have textured hair that reverts, it’s important to consider heat protection that will not counteract by reverting your hair.”

When Do I Use Heat Protectant?

Heat protectant isn’t one-and-done. Just because you use it on damp hair ahead of your weekly blowout, doesn’t mean the protection lasts through day two styling. You need to reapply the product before using a hot tool. “Ideally, you limit your heat styling to only one to two times a week to keep your hair healthy,” says Brook. If you are worried about product buildup or weighing down your hair, look for formulas that use words like lightweight or flexible, suggests Washington.

How to Apply Heat Protectant

It's best to apply your heat protectant evenly throughout your hair, focusing more on the mid-lengths to ends where hair is typically more prone to damage from heat styling. "You should avoid applying too much product at the roots to prevent weighing down your hair or making it look greasy," notes Washington.

Do All Hair Types Need Heat Protectant?

Whether your hair is straight, wavy, curly, or coily, it's important to use a heat protectant before picking up a blow dryer or hot tool. "If heat is going to touch your hair in any way, you should also use a heat protectant," emphasizes Washington. "It is my number one rule for my clients to follow."
