Olaplex No.4 Bond Maintenance Shampoo 250 ml

No.4 Bond Maintenance Shampoo brings Olaplex's salon bond-building technology into the shower. Its active ingredient reconnects broken disulfide bonds inside the hair, so damaged, colour-treated hair becomes stronger and smoother with every wash.

The formula is sulfate-free, paraben-free and vegan, safe for colour and keratin treatments, and adds shine and manageability without weighing hair down. It suits all hair types.

Apply to wet hair, lather and rinse; follow with No.5 conditioner. 250 ml.
