Biolage Smooth Proof Shampoo is specially formulated to tame frizzy or unruly hair. Enriched with camellia and glycerin, it gently cleanses while smoothing the hair fiber. Free from silicone, parabens, and weight-bearing agents, it creates a protective shield against humidity to minimize frizz. The result: softer, more manageable hair with a natural shine. Ideal for damaged hair or hair exposed to humid conditions. Directions: Apply to wet hair, lather, rinse, and then follow with Smooth Proof Conditioner for best results.
