OLAPLEX No. 9 Bond Protector Nourishing Hair Serum is a leave-in antioxidant hair serum to shield from pollution and heat that cause tangles, breakage, and static. OLAPLEX Bond Building Technology is paired with potent, antioxidant-rich Red Algae Extract to nourish hair, block pollutants, and neutralize free radicals. See satin shine, style memory, bounceback curls, anti-tangle and anti-static action, and heat protection for all hair types.

Apply a small amount to damp, towel-dried hair working upward from ends to roots. Use more as needed for longer, thicker hair. Air-dry for a soft texture. Blow-dry for a smooth finish. Diffuse for waves or curls. Apply sparingly to dry hair for frizz and static control and added shine.
