10 Best Heat Protectants of 2024, According to Hairstylists

And don’t skip the directions. “I know it seems very common sense—but if [the bottle] says to use a pea-sized amount, use a pea-sized amount. Maybe bump it up to a quarter-size if you have more hair, but definitely don’t overuse or underuse the product,” Maria says. Still not getting the results you want? “Watch videos—go on Instagram or YouTube,” she recommends. ”Get a little education on how to use it properly.”

FAQs

Can I use heat protectant on dry hair?

Yep: “They can be used on both wet hair and dry hair,” says Alvarez. “Some are actually meant for dry hair and are activated by heat. These usually tend to create hold in the hair as well” to make your ‘do last longer.

How do I choose the right heat protectant for my hair type?

“Heat protectants work in the same way, whether they’re a cream or a spray,” says Alvarez. “Sprays tend to be lighter and less hydrating, so I’d use them for fine to medium hair. Creams are heavier and should be used for thicker hair.” Maria adds that if you have curly or coily hair, you may want to use a leave-in conditioner before your heat protectant to lock some extra hydration in as you style.

Can I use leave-in conditioner as a heat protectant?

Some leave-in conditioners also double as heat protectants, but not all of them. Check the product label to confirm that it offers heat protection before relying on it during styling.

Dream Coat Supernatural Spray Anti-Frizz Treatment

Pros

  • Sephora shoppers say it leaves their hair looking glossy and smooth
  • Results should last for several washes

  • Reviewers say you need to apply a lot of the product for it to work

Color Wow’s Dream Coat Treatment is a must-have if you’re always battling humidity-induced frizz. It’s activated by heat—after you apply it all over, you’ll need to use a blowdryer (or a blowdryer brush, like the SELF fave Shark SmoothStyle) or another hot tool to smooth your strands. The results can last up to four shampoos later—and, while that might sound too good to be true, Sephora reviewers confirm that it really works. Plus, the ultra-lightweight formula offers flyaway control without weighing your hair down or leaving it looking greasy.

“I’ve used a bunch of heat protectants—most sprays don’t do anything for the frizz, and oils make me look really greasy,” says one SELF staffer with “super thick hair.” “The Color Wow one legit is the perfect balance. My flyaways and split ends look so much smoother, and it actually allows my coarse hair to hold curls with a salon-like finish.” She also loves that it doesn’t have much of a scent.
