Betraying its chic, minimalist appearance, this brilliant bottle holds miracles. So much more than a hair treatment, OLAPLEX's three-step ritual is a system that permanently rebuilds the damaged disulphide bonds in your hair – which are compromised as a result of colouring, heat styling and everyday wear and tear. A daily cleansing and repairing shampoo, this silky fluid deeply hydrates and strengthens hairs as well as repairing shattered hair bonds in between your salon or styling sessions, so you can carry on maintaining your favourite hair colour and style without the worry of damaging your hair beyond repair. No.4 Bond Maintenance Shampoo formula is colour- sulphate- paraben- gluten- and nut-free, as well as vegan-friendly too. Use after the brand's No.3 Hair Perfector weekly treatment and follow with the No 5 Bond Maintenance Conditioner.

Apply to damp hair, work through hair from root to tip creating a lather. Wash off then follow with the No.5 Bond Maintenance Conditioner. Can be used alongside the weekly No.3 Hair Perfector treatment.

Have you noticed your hair become dry, brittle and elastic since you began bleaching, perming or heat-styling? Let us introduce you to OLAPLEX. Starring a patented active ingredient that works on a molecular level, OLAPLEX formulas seek out broken bonds in the hair (which are caused by chemical, thermal and mechanical damage) and repair them, restoring compromised hair to former glory. Previously only available in salons, the OLAPLEX No.4 Bond Maintenance Shampoo repairs hair bonds while gently cleansing hair, imparting deep moisture and strength (it's the perfect follow-up to the incredible No.3 Hair Perfector).
