A concentrated bond-care shampoo that gently cleanses while repairing and strengthening from root to tip — the everyday shampoo step for any hair type maintaining OLAPLEX results at home.
What It Is
Nº.4 is the daily shampoo step in the OLAPLEX system. Unlike most shampoos that simply cleanse, Nº.4 continues the bond-building work of the treatment steps at the wash stage. The result is hair that gets progressively stronger with every wash rather than progressively more fragile from the surfactant contact.
The formula is concentrated — a small amount goes a long way, which matters for a daily-use product. It lathers well on wet hair, rinses cleanly and leaves hair noticeably shinier and softer than before washing. Colour-safe and suitable for all hair types and chemical services.

How To Use

Moda Pro Tip
OLAPLEX formulas are concentrated — start with less product than you think and add water to build the lather. Using too much shampoo is the most common reason clients feel like it is not working; the formula is already cleaning, it just does not need to foam dramatically to do it.
Key Ingredients + Technology
OLAPLEX Bond Building Technology in a concentrated, colour-safe surfactant system that repairs bonds at the cleanse step rather than waiting for the treatment step.
Why Moda Carries This
OLAPLEX pioneered bond building and clients ask for it by name. Nº.4 is the shampoo that keeps the whole system consistent — using it between treatments means the bond-repair work is reinforced at every wash rather than only on treatment days.
