Your hair needs a product that can stand up against daily styling aggressors. Nexxus Prep & Protect Leave-In Spray is enriched with our PROTEINLOCK formula to form a protective barrier that protects hair from heat and styling damage. This heat protectant hair spray is formulated with elastin protein and hyaluronic acid to weightlessly moisturize, easily detangle, boost shine, and add softness.

We recommend using this leave-in spray before styling hair with our Weightless Styling products for additional protection for your hair.
