Just after colouring your hair, it has never been so bright & intense that you love it! But, from the first shampoo, it washes away & begins to fade. The Color Locker acts before the shampoo to fix the pigments to the core of the fiber. The Phyto Phytomillesime Color Locker complex, a vegetal origin, forms a protective barrier to trap pigments & prevent them from washing away whilst rinsing hair. Perfectly protected with every shampoo, the colour is preserved & its hold is extended.
