~ AFFINAGE_Colour_Dynamics Customise your hair with electrifying vibrancy, subtle tones or incredible soft pastel effects. Colour results can be easily adjusted according to the degree of pre-lightening - the lighter the base, the brighter the colour! You can also vary the intensity of the colour by adjusting the processing time. Colour Dynamics are the ultimate fashion colours which wash out gradually depending on the frequency of shampooing. Colour Dynamics is a gentle low pH formula with no ammonia or peroxide leaving hair with glossy vibrant colours.
