About N°4

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.

PH Balance: 6-6.5

From the people

“The quality of this product is unbelievable...I have frizz from breakage and some dull dryness from coloring and the shampoo and conditioner delivered on their promises and then some. My hair is so soft and smooth. Can't say enough how much I love these products.”
