Keratin Colour is Italian colour cream specially formulated for professionals. This exclusive formula contains Protesil and Keratin. Protesil protects hair ensuring softness and shine. Keratin locks in colour and reduces fade whilst colour is intensified. Keratin also leaves hair soft, silky-smooth and healthy looking. The Tridimensional structure of each shade enhances the resistance of colour from fading and washing. Its conditioning components flatten the surface of the hair fibre decreasing the porosity of chemically treated hair creating a greater shine.
