Do I really need to use a heat protectant spray?

Yes heat protectant creates a barrier between the hot plates and your hair cuticle, reducing moisture loss by up to 50%. Without it, the heat literally boils the water inside your hair shaft, causing permanent structural damage over time. Apply heat protectant to towel dried hair before blow drying, or to dry hair before flat ironing. This one step makes the biggest difference in long term hair health.
