A gentle formula which helps to maintain colour vibrancy while effectively cleansing the lengths, the Biolage Colorlast Shampoo Duo protects colour depth, tone and shine between salon treatments. Taking inspiration from the orchid, a flower believed to have fade-defying properties, the shampoo plumps the hair with moisture, nourishing the strands from root to tip. A do-it-all formula, the shampoo additionally seeks to provide defense against environmental aggressors. Vegan. Set Contents: Colorlast Shampoo 2 x 250ml
