Olaplex No.9 Bond Protector Nourishing Hair Serum 3 oz

Olaplex No.9 Bond Protector Nourishing Hair Serum is a weightless leave-in that shields the hair while it builds bonds from within. Worked through damp or dry hair, it forms an invisible barrier that guards against pollution, static, and heat up to high styling temperatures, so daily wear and hot tools do less damage. Antioxidants and bond-building science nourish and strengthen the strand, boosting shine and smoothing frizz without any greasy weight. It primes hair for styling and layers cleanly under other products. Silicone-free, sulfate-free, vegan, and color-safe, it suits every hair type as an everyday first step toward healthier-looking hair.
