No.4 helps increase moisture levels and helps add shine and manageability. It’s a luxurious, highly-moisturising, shampoo that helps leave hair easy to manage and healthier looking with each use.

As with the rest of Olaplex products, Olaplex No.4 is completely non-toxic as well as sulfate-free, paraben-free, vegan, gluten-free, nut-free, and colour safe. For best results, use the 3-4-5 system at home.
