A highly-nourishing and reparative shampoo

N°4 Shampoo repairs and protects hair from everyday stresses - including damaged hair, split ends, and frizz - by re-linking broken bonds. Leaves hair easier to manage, shinier and healthier with each use. N°4 is color-safe and proven to reduce breakage and strengthen all types of hair.

Highly concentrated purple shampoo cleanses, tones, and repairs while keeping hair hydrated from roots to ends. Sulfate-free formula creates a rich lather to neutralize brassiness and boost brightness after one use for all blonde, lightened, and grey hair.
