Vitamino Color conditioner (part of the Serie Expert range from L'Oréal Professionnel) is an intensely nourishing treatment especially designed to protect hair colour. Regular use will make coloured hair softer and more radiant with each wash. The colour protection comes from Resveratrol, a powerful polyphenol, which protects colour from fading for up to 8 weeks, while nourishing, conditioning and boosting shine. For best results, begin by washing hair with L'Oréal Vitamino Color shampoo before conditioning with Vitamino Color conditioner.
