Wella Invigo color Brilliance shampoo is the perfect tool to protect the color of coarse colored hair. Thanks to the low pH level, this shampoo closes up the hair cuticle right after the hair dyeing process, making sure that the color pigments stay longer in the hair. Copper encapsulating molecules help support the brightness of the hair; histidine and vitamin E control the oxidation process after the coloring and protects the newly acquired color.
