Biolage Color Last Shampoo for Color-Treated Hair — 33.8 fl oz, Low-pH Formula & Shine-Boosting

Biolage Color Last Shampoo is a low-pH, soybean-oil and stearic-acid formula that gently cleanses color-treated hair while helping preserve color and boost shine.

This salon-grade shampoo is formulated specifically for dyed and color-enhanced hair. Its color care concentrate uses antioxidant-rich soybean oil and stearic acid to create a lightweight protective veil over each strand, reducing the factors that cause hue shift and dullness. The vegan, cruelty-free bottle is made from 100% recycled plastic and avoids parabens, mineral oil, and added colorants, making it a responsible pick for everyday color maintenance.

How does Biolage Color Last Shampoo protect color between salon visits?

The shampoo’s low pH and micro-dosed soybean oil help seal the hair cuticle and reduce color washout during cleansing. Stearic acid adds a smoothing layer that helps reflect light and maintain tone clarity.

• Low-pH formula to minimize cuticle lift
• Soybean oil delivers antioxidant protection
• Stearic acid smooths and seals the hair surface
• Tested to help preserve color vibrancy for up to 4 weeks when used with the conditioner*

What difference will I see after one use?

From the first wash, hair appears shinier and feels smoother thanks to the nourishing concentrate. The formula cleans without stripping, so color looks fresher and hair has improved manageability right away.

• Notable increase in shine after a single application
• Softer, easier-to-comb strands
• Gentle lather that removes impurities without fading color

Is this shampoo safe for chemically treated or fragile hair?

Biolage Color Last is designed for color-treated and chemically processed hair: it cleans while supporting strength and hydration. Because it’s free from parabens and mineral oil and uses a mild pH, it’s suitable for delicate, colored hair when used as directed.

• Vegan and cruelty-free formulation
• No parabens, mineral oil, or added colorants
• Pairs with Color Last Conditioner for added nourishment

How should I use this shampoo for best results?

Apply to thoroughly wet hair, massage to create a gentle lather, then rinse completely. For optimal color preservation and moisture balance, follow with Biolage Color Last Conditioner and use the system regularly.

• Wet hair thoroughly before application
• Massage gently—avoid aggressive scrubbing
• Rinse and follow with Color Last Conditioner
• Use consistently to help maintain color vibrancy

Who is this for: Biolage Color Last Shampoo is tailored for anyone with color-treated hair seeking a professional-strength, eco-conscious cleanser that maintains tone and increases shine. It’s a good choice for salon-colored, highlighted, balayage, or chemically treated hair types that need gentle cleansing, added smoothness, and long-lasting color appearance without harsh additives.
