What’s heat protectant spray?

Heat protectant spray—also known as thermal spray or thermal protection spray—is currently one of hottest hairstyling trends. Before you consider it excessive, think for a while how beneficial this product actually is. With just one cosmetic you can improve the appearance of your locks and shield them from heat damage.

Even the ease of use makes a heat protectant spray a product worth having close at hand: you simply spray your strands with it before grabbing a blow dryer or a flat iron, or before going to the beach. Yes, that’s right, a product like thermal spray also keeps your tresses safe by locking moisture inside the shafts when you’re sunbathing or goofing around with your friends in the sun.

Taking this one simple step, you can stop worrying whether you’re causing irreversible damage to the hair when the temperature rises. No dryness, no brittleness, no splitting. It’s pretty incredible that applying a heat protectant spray takes just a few seconds but the benefits it brings out are enormous and long-lasting.
