The chemical processes used for dyeing the hair, with time, damage the capillary fibre.
Dyeing results are never permanent, for the exposure to agents such as sunlight ends up distorting their action.
The simple fact of washing the hair, as well as its exposure to any other chemical processes, contributes to a progressive loss of the applied colour.
The COLOR PROTECT range counteracts the action of all these elements which damage the hair and reduce its colour intensity, dulling its shine.
