Discover the best heat defense sprays to protect your hair from damage. Learn how to prevent heat damage and maintain healthy, vibrant locks.

Whether you love bouncy blowouts, sleek flat-ironed style, or voluminous curls, you know heat defense hair spray is a must-have for thermal styling. Heat styling without proper heat protection can easily cause damage resulting in dry, brittle hair, breakage, and split ends. Using heat protection is the key to keeping your locks healthy, hydrated, and strong. Explore what heat damage is and how you can help shield your hair from its effects.

Hair is made of the protein, keratin. It is protected by the cuticle which is the outer layer of the hair. When heat is applied—especially at temperatures of over 300°F—the cuticle layer breaks down and robs the hair of its moisture. As the cuticle lifts, the hair becomes more porous and, therefore more prone to dryness, frizz, and split ends.

Excessive heat styling can weaken the inner cortex, and lead to breakage and thinning over time. That's why heat damage is more than cosmetic, it’s structural damage to the hair shaft so using a heat protectant spray to shield every strand is important to maintaining healthy looking or healthy feeling hair.

Before you turn on your hot tools, be sure to reach for the heat protectant spray. Apply it to damp or dry hair and adjust the heat setting based on your hot tool according to your hair type for the best result. Low to medium heat is best for fine or color-treated hair, and medium to high for thick or coarse textures. Think less is more. The goal is to use the lowest temperature setting to deliver the most effective result for your hair type. Here are some of the best heat-defense hair products to try.

Lastly, trim your hair regularly. Keeping ragged, frayed strands clipped prevents split ends and helps promote healthier growth and smoother-looking hair.
