Olaplex No. 9 Bond Protector Nourishing Hair Serum 3oz.

Start with damp lengths

Work a small amount through towel-dried hair, from ends up to roots. The serum feels weightless and silicone free, so it won't sit on fine strands or blur curls. You can add more where hair drinks it in.

Guard against daily stress

Powered by OLAPLEX technology, it brings antioxidants to help neutralize free radicals from pollution. That matters on city days, after a commute, or when your hair looks dull by noon. It also helps shield against heat styling and breakage.

Shape your finish

Air-dry for soft texture, blow-dry for a smoother look, or diffuse when you want waves and curls to keep their shape. A little goes a long way, and the slip makes combing easier without the coated feel.

Use it your way
