Biolage Color Last Shampoo for Color-Treated Hair — 33.8 fl oz, Low-pH Vegan Protection

Biolage Color Last Shampoo is a low-pH, vegan shampoo formulated with soybean oil and stearic acid to gently cleanse and help preserve vibrancy and shine in color-treated hair.

Formulated for salon-quality upkeep at home, this large 33.8 fl oz bottle of Biolage Color Last Shampoo uses a micro-dosed color care concentrate to remove impurities while minimizing color washout. The plant-derived soybean oil and stearic acid work together to nourish strands, add surface smoothness and create a lightweight veil that helps maintain tone and luster between professional services. The formula is paraben- and mineral oil-free, vegan, cruelty-free and packaged in bottles made from recycled plastic.

How does this shampoo protect color during regular washes?

The low-pH formula helps keep cuticle scales closer to the hair shaft, which reduces color loss during cleansing. Antioxidant-rich soybean oil and stearic acid create a protective layer that locks in moisture and surface smoothness, so pigments remain more stable over time.

• Low-pH cleansing to support cuticle integrity
• Soybean oil provides antioxidant nourishment
• Stearic acid adds a lightweight sealing effect
• Consumer test: helps prevent color fade for up to 4 weeks when used with Color Last Conditioner*

What immediate benefits will I notice after one wash?

From the first use hair typically feels smoother, looks shinier and appears more vibrant. The formula is designed to rinse clean without leaving heavy residue, so color-treated hair feels light yet conditioned.

• Up to 35% more shine reported after one use*
• Smoother surface for easier detangling
• Non-greasy conditioning that won’t weigh down color-treated hair

Is this shampoo safe for chemically treated or fragile hair?

Biolage Color Last Shampoo was created with the needs of color-treated and chemically processed hair in mind. It gently cleanses while providing strengthening and hydration to help reduce the look and feel of damage without harsh sulfates or unnecessary additives.

How should I use it for best results with my color routine?
