Matrix Biolage Colorlast Color Protecting Mask (500ml) is a professional-grade, intensive deep-conditioning treatment designed to preserve the depth, tone, and shine of color-treated hair. Inspired by the fade-defying orchid, its low-pH, silicone-free formula wraps strands in 360-degree nourishment, smoothing the hair cuticle to lock in color pigments while preventing heavy product buildup. Infused with UV filters and botanical antioxidants, it actively shields hair from environmental damage, dryness, and frizz—leaving your hair exceptionally silky, radiant, and salon-vibrant for weeks.
