Olaplex No.9 Bond Protector Nourishing Hair Serum 90ml is a revolutionary leave-in treatment designed to shield your hair from daily damage while delivering weightless nourishment, shine, and styling support. Formulated with Olaplex’s patented bond-building technology, this vegan, antioxidant-rich serum works at a molecular level to protect and fortify the hair, helping it look and feel healthier with every use.

In today’s environment, your hair is exposed to multiple stressors — from heat styling to pollution and UV rays — all of which can lead to dullness, breakage, and weakened strands. Olaplex No.9 is your first line of defense. Infused with red algae extract and a powerful blend of antioxidants, this lightweight, silicone-free serum helps neutralize free radicals, forming an invisible shield against pollution for up to 48 hours while also offering heat protection up to 450°F (232°C).

Designed for all hair types, including color-treated, curly, and chemically processed hair, this serum detangles, smooths, and enhances manageability without buildup or greasiness. It instantly improves hair’s movement, bounce, and shine, making it a perfect prep step before blow-drying, air-drying, or styling.

The silky, lightweight formula absorbs quickly into damp or towel-dried hair, leaving it soft, shiny, and protected — ready to take on styling and the elements with resilience.
