The Nº.4 Bond Maintenance Shampoo, infused with patented OLAPLEX Bond Building Technology, is a highly concentrated reparative shampoo that hydrates and nourishes hair.

Helen's Take 🧐

A good option after the coloring service. Make sure you use it for 2 weeks after coloring your hair (maximum of 3 weeks). Because it is concentrated and repairing, this product can overwhelm your hair. The shampoo is more on the heavier side (more of a treatment for the hair)- it is loaded with hair-care ingredients. But after 2 weeks of use, switching to another more light day-to-day version is better.
