Olaplex Bond Protector Nourishing Hair Serum No. 9 90ml/3.1FL.OZ.

A leave-in serum that shields hair from environmental and styling damage. Its antioxidant-rich, silicone-free formula nourishes hair, blocks pollutant exposure and neutralizes free radicals, yielding a satin-like shine and noticeable resistance to heat (up to 450F). Suitable for all hair types, it helps promote better style memory, curl bounceback, tangle- and static-control. To use, apply a small amount to damp hair working from ends to roots - use more for longer, thicker hair. Air-drying will yield a soft texture while blow-drying creates a smooth finish. For waves or curls, try diffusing; apply sparingly to dry hair for additional frizz and static control and a glossy look.
