Biolage Color Last Shampoo Refill for Color-Treated Hair, 16.9 fl oz — Low-pH, Vegan, Nourishing Shine

Biolage Color Last Shampoo Refill is a vegan, low-pH cleansing refill that helps protect and prolong the vibrancy and shine of color-treated hair.

If you color your hair and want a gentle daily cleanser that supports tone and gloss, this concentrated refill pouch is formulated with soybean oil and stearic acid to nourish strands while minimizing color fade. The low-pH formula cleans without stripping, leaving hair smoother, stronger, and visibly shinier after use. Packaged as an eco-friendlier refill compatible with your Biolage Color Last bottle, it reduces plastic waste while delivering salon-inspired care at home.

How does this shampoo help color look fresher between salon visits?

The formula uses micro-dosed soybean oil and stearic acid to create a protective surface on hair, helping preserve the depth and tone of dyed strands. Its low-pH balance gently removes buildup without opening the cuticle excessively, which reduces the speed of color washout.

• Soybean oil supplies antioxidant-rich lipids to condition and seal moisture.
• Stearic acid forms a lightweight barrier to shield pigments from external aggressors.
• Low-pH cleansing minimizes cuticle lifting that can accelerate fading.

Will this refill improve hair texture and shine after one use?

Yes — the concentrated care in the shampoo aims to smooth the hair surface and boost reflectivity, so hair appears glossier and feels softer after a single wash. Regular use supports smoother, more manageable strands and contributes to a stronger-looking finish.

• Formulation smooths cuticle scales for increased shine.
• Conditioning lipids help detangle and reduce friction.
• Designed to support hair resilience to styling stress.

Is this product safe for long-term use on color-treated hair?

The shampoo is crafted without parabens, mineral oil, or added colorants, and is vegan, which makes it suitable for routine use on color-treated hair. Using it as part of a color-care system (shampoo plus conditioner) helps extend the visual life of hair color while keeping hair hydrated.

• Free from parabens and mineral oil to limit harsh residues.
• Vegan formulation with no animal-derived ingredients.
• Refill pouch reduces plastic and supports sustainable use.

How should I use the refill to get the best results?

Pour the refill into your original Biolage Color Last bottle and use on wet hair, massaging to lather and rinsing thoroughly. Follow with Color Last Conditioner for optimal color maintenance and manageability.

• Transfer refill into the original pump bottle for easy dispensing.
• Apply to wet hair, lather gently, then rinse completely.
• Use conditioner afterward to lock in moisture and tone.

Who is this for: This refill is aimed at people who regularly color their hair and want a gentle, salon-grade cleansing option that supports color longevity and shine while reducing environmental impact. It suits anyone seeking a vegan, low-pH shampoo that conditions, strengthens, and refreshes dyed hair without harsh additives.
