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

Biolage Color Last Shampoo Refill is a vegan, low-pH cleansing refill that nourishes color-treated hair with soybean oil and stearic acid to help preserve color, add shine, and improve manageability.

This refill pouch delivers the Color Last cleansing formula in a more sustainable format so you can refresh your bottle while reducing plastic waste. Formulated for color-treated hair, the shampoo gently removes buildup without stripping pigments and supports a smooth, high-shine finish. Key actives—soybean oil and stearic acid—work together to condition strands and form a lightweight barrier that helps guard color from everyday aggressors.

How does this shampoo help maintain hair color between salon visits?

The formula is designed with a low pH and a micro-dosed concentrate of soybean oil and stearic acid to gently cleanse while protecting pigment. By smoothing the hair cuticle and forming a thin protective veil, the product helps reduce color fade from washing and environmental exposure.

• Helps prevent color fade for up to 4 weeks when used with Color Last Conditioner*
• Low-pH cleansing helps preserve artificial pigments
• Soya-derived oil nourishes and seals moisture into the hair shaft
• Stearic acid creates a weightless protective coating

What improvements in shine, strength, and texture can I expect?

After a single use, this shampoo is shown to noticeably boost shine, smoothness, and tensile strength compared to untreated hair. The combination of conditioning oil and smoothing agents reduces friction and flyaways for easier styling and a polished appearance.

• Reported 35% more shine after one use
• Smoother hair—up to 13x improvement after one use
• Stronger-feeling hair—reported 2x strength increase after one use
• Improves manageability and reduces surface roughness

Is this refill eco-friendly and safe for sensitive routines?

The refill pouch is designed to lower single-use plastic compared with buying a new bottle, and the formula avoids certain controversial ingredients. It’s vegan and free from parabens, mineral oil, and artificial colorants, plus the bottle and cap are made from recycled plastic.

• Refill pouch uses 62% less plastic versus a full bottle option
• Vegan formula—no animal-derived ingredients or byproducts
• Paraben-free, mineral oil-free, and colorant-free
• Bottle and cap produced with recycled plastic content

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

Pour the refill into your existing Biolage bottle and use as your regular shampoo. Apply to wet hair, massage to lather, then rinse thoroughly; follow with Color Last Conditioner for optimal color care and lasting tone preservation.

• Transfer refill into an upright shampoo bottle for easy dispensing
• Use on wet hair—massage scalp and lengths, then rinse
• Pair with Color Last Conditioner to extend color vibrancy and smoothness
• Suitable for regular use as part of a color-care regimen

Who is this for: This refill is aimed at people with color-treated or highlighted hair who want a gentle, performance-driven shampoo that supports color longevity, adds shine, and improves manageability while reducing plastic waste. It’s a fit for those seeking a vegan, paraben-free option that pairs with a color-care routine.
