14 Best Heat-Protectant Sprays to Prevent Serious Hair Damage

If you’re styling using heat, you should be using a heat-protectant spray.

Heat-protectant sprays are like the sunscreens of the hair care world. They create a protective barrier between your strands and the scorching temperatures of hot tools like flat irons, hair dryers, curling irons, and blow-drying brushes.

Best Heat-Protectant Sprays

    Just like your favorite hair oil or leave-in conditioner, these heat-protectant sprays are incredibly easy to use. All you have to do is spritz them through your damp or dry hair before you start styling. Heat-protection sprays also lock in moisture, which can help improve the effectiveness of your hot tools, thanks to their frizz-reducing, shine-boosting, and split end-sealing capabilities. If you regularly skip using one before thermal styling, your cuticles will eventually become dry, brittle, dull, and break off. The damage is noticeably bad if you have color-treated hair, since your perfectly highlighted or dyed mane will fade quickly.

    Whether you're using a travel-sized hair dryer or rotating curling iron, these are the best heat-protectant sprays that will prevent you from frying your tresses.
