Biolage Color Last Conditioner is a professional salon-grade treatment designed to protect and extend the vibrancy of color-treated hair. Formulated with a low pH balance and inspired by nature's fade-defying orchid, this conditioner seals the hair surface to lock in color depth and tone for up to 4 weeks. Infused with antioxidant-rich soybean oil and stearic acid, it creates a lightweight protective shield against environmental fade while delivering 35% more healthy-looking shine. The formula leaves hair exceptionally soft, detangled, 13x smoother, and twice as strong after just one application—making it ideal for chemically processed or dehydrated strands. This weightless conditioner works on all hair textures without flattening fine strands. It's 100% vegan, cruelty-free certified under the Leaping Bunny program, and free from parabens, mineral oil, and colorants. Apply from mid-lengths to ends after shampooing, leave for 1–3 minutes, then rinse with warm water. Finish with cool water for maximum shine.
