Encouraging true-to-tone colour, the Biolage Color Last Shampoo cleanses and nourishes the hair while maintaining shade vibrancy and depth. The low pH formula works to gently remove impurities from the scalp and strands, as a micro-dosed colour care system, made of antioxidant-rich soybean oil, delivers colour protection and preservation. Meanwhile, omegas and fatty acids provide long-lasting shine and suppleness after each wash, sealing in the luminosity of your shade.
