What It Is

A multi-benefit healthy hair serum, powered by OLAPLEX® technology. OLAPLEX® No. 9 Bond Protector Nourishing Hair Serum is a silicone free, weightless, antioxidant-rich serum that enhances any hair routine to protect & perfect all hair types and textures.

What It Does

Pollution damages our hair everyday, leaving it dull, lifeless, difficult to style and ultimately resulting in broken bonds. No.9 is packed with antioxidants to neutralize free radicals, act as a shield against pollution, guard the hair from breakage and protect against heat styling.

Apply a small amount to damp, towel-dried hair, working upward from ends to roots. Add more as needed. Air-dry for soft texture. Blow-dry for a smooth finish. Diffuse for waves or curts. Scan the QR code for education and videos by hair type & texture.
