11 Heat Protectants That Will Shield Your Hair From Hot Tool Damage
Yes, you need to use one.
Admit it: We all low-key love hot tools. Curling irons, straighteners, and blow dryers can totally transform our hair from a frizzy mess to bouncy and shiny. Whether we want to add life and volume or create sleek shine, hot tools are sometimes the only way we can get our stubborn hair textures to oblige. But it's no secret that subjecting our strands to high heat on the regular can wreak havoc on their vibrancy and health, leading to dull, brittle hair and even split ends. One way to save your strands from sizzling under the scorching heat? A heat protectant.
By coating the hair with ingredients like silicones and nourishing amino acids, heat protectants work to seal the hair cuticle and protect it from losing moisture and elasticity due to contact with high heat. And as any good hairstylist will tell you, they're a must to apply before cranking up the degrees on your straightener or curling iron.
"It is imperative that everyone use a product on their hair simply to protect from the natural elements and excess heat," says celebrity hairstylist Clariss Rubenstein. "Every hair type needs a barrier between itself and solutions and other things that can penetrate the hair and possibly cause damage. And the right heat protectant can feel like it's not even there."
Just keep in mind that while heat protectants can provide a shield for contact with high heat, they can only reduce the amount of damage caused by heat styling—not completely protect your hair. So while the only way to really eliminate damage is to put down the hot tools, these sprays are an easy solution for when you just have to have those perfect flat iron curls.
Best Heat Protectants for Hair:
Shield your hair from heat with nourishing ingredients like sunflower seed, green tea, and aloe vera extracts, which coat strands and lock in moisture and shine. "It reduced the blowout time and my hair felt silky and smooth after just one use," one tester said during our annual Beauty Crush Awards, reporting that after a few hours her hair was still frizz-free.
This protection spray keeps hair safe from thermal damage up to 450°F and shields it from harmful UV rays and pollution. The product is packed with nourishing ingredients, like rosemary leaf extract to protect hair from free radical damage, glycerin to hydrate and soften hair, a vitamin B blend to condition and strengthen it against breakage, and caffeine to rejuvenate hair follicles and energize the scalp.
Rubenstein loves this drugstore beauty buy for a smooth look. She says that she uses it when she wants to make her A-list clients' hair super shiny while still looking clean (not greasy or weighed down) with lots of movement. Antioxidants from Camelina sativa seed oil protect the hair while calming frizz and flyaways, and hair is protected up to 450ºF. If you're a frequent flat iron user, Rubenstein recommends you give this affordable spray a try.
Another favorite of Rubenstein's, this heat protectant is packed with botanicals, including blue agave nectar, which hydrates and treats hair while guarding against heat styling. "I love using it when I curl or wave hair because it boosts volume," Rubenstein tells us. "It has a nice medium hold without feeling stiff or sticky. I'd recommend you spray a little on damp hair, blow-dry, and add a little more before using your curling or flat iron."

When applied to damp hair before blow-drying, this award-winning leave-in spray protects hair from high temps and leaves it shiny and soft.

This tried and true drugstore heat protectant stands up against curling irons, flat irons, and blow dryers because it uses heat-activated technology to seal in the hair cuticle and fight damaging friction. We love it for the trigger spray that offers easy all-over misting, plus the lightweight, non-greasy formula that doesn't weigh hair down.
CHI's weightless heat protectant formula is clearly made by the makers of hot tools. This spray does not play when it comes to protection.
