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.
The only patented system to noticeably repair extreme damage—turn dry, brittle hair into soft, shiny, and more resilient hair.
