What is Heat Protectant?

Heat protectant is a product that reduces damage to your hair when used before heat styling. (Note that we say it reduces — not prevents. More on that later.) It’s often a spray, cream, or serum that you leave in your hair (damp or dry), although there are also formulas you rinse out in the shower. Some products have additional benefits, such as combining heat protection with a leave-in conditioner or a styling cream.

How Does Heat Protectant Work?

Heat protectants add a barrier between your styling tool and your hair, sealing in moisture and fending off frizz. They also work to smooth the cuticle, making your hair look smooth and feel soft. Quality heat protectants contain ingredients like humectants (like panthenol and propylene glycol), which preserves moisture and blocks frizz; amino acids (like keratin), to strengthen hair and provide antioxidants; and natural oils and extracts (like aloe), which protect and seal the hair’s cuticle. While some products rely on silicones (like dimethicone and cyclomethicone) and water-based polymers (like polyquaternium and acrylate copolymer), these ingredients can leave a film on some hair types and end up weighing it down — so some prefer to avoid them.

When Do I Use Heat Protectant?

Depending on the type of heat protectant, you may apply it on damp hair or dry hair before using any hot tools, including blow dryers, curling irons, and straightening irons. Apply section by section, and comb through to distribute the product evenly.

If you must heat style, do so in moderation to avoid heat damaged hair. Lower the temperature (staying under 350 degrees is best, or even lower for fine hair), and don’t forget that heat protectant for hair! Your locks will thank you
