Heat Protectant Spray: A Buying Guide

We often need to use styling equipment like blow-dryers, straighteners, and curlers. But all these are not good for our hair health and cause damage every use. A heat protectant spray minimizes this damage and ensures a safe styling. But, these leave-in products now have many more features and benefits. Choose a spray that can fulfill all your purposes with this complete buying guide.

Why Do You Need a Heat Protectant Spray?

Curlers, straighteners, and blow dryers release enormous heat on your hair while you style your hair with them. This heat can strip off the natural or artificial color pigment in your hair, causing frizzy and brittle hair. A heat protectant spray minimizes this damage because of high heat from a hot tool by adding a protective coat to your hair.

It is ‌a leave-in product applied before styling. These sprays also come with nourishing, hydrating, and conditioning benefits, leaving your hair smooth, silky, fragrant, and shiny afterward.

Ingredients To Look for in a Heat Protectant Spray

Some hair protectant sprays contain water-based polymers like acrylate copolymer and polyquaternium, while others have silicones like Cyclomethicone. You can consider the following ingredients in a heat protectant spray while buying:

Argan oil

This oil nourishes hair and skin. With the richness of antioxidants, essential fatty acids, and vitamins, it safeguards and seals your hair's cuticle, ensuring strength.


Keratin is a structural protein that builds your hair. A keratin-rich hair protectant spray can help strengthen and nourish your hair.

Vitamins A and E

Vitamins A and E infused heat protectant spray helps protect your hair against damage.

Vitamin B5, panthenol

Vitamin B5 improves manageability, reduces hair loss, boosts volume, and strengthens hair against breakage. Panthenol is a moisturizing compound derived from Vitamin B5. It attracts moisture in the hair and locks it in.

What To Consider While Buying a Heat Protectant Spray

Hair type

Most hair protectant sprays suit all types of hair. But some come specially formulated for a particular hair type. So, it would be better to consider the hair type while making the purchase.

Sulfate-free and paraben-free formula

Heat protectant sprays are leave-in products. So, look for a sulfate-free and Paraben-free formula as you don't want to harm your scalp and hair with these toxic chemicals.

Texture of Spray

Invest in a weightless, no-hold, non-sticky formula that does not leave a residue on your hair. If you have artificially colored hair, be sure to go for sprays that are ‌safe on colored hair.


You may not like to invest in a product that smells unpleasant. That said, you may not want to use products with a strong fragrance. So, look for a product that has a pleasant light smell.

Vegan and cruelty-free

Remain guilt-free with your purchase by buying a 100% vegan and cruelty-free heat protectant spray.
