Biolage ColorLast Purple Shampoo for Color-Treated Blonde Hair, 13.5 fl oz — pH-Balancing, Brass-Neutralizing

Biolage ColorLast Purple Shampoo is a low-pH, pigment-depositing shampoo that neutralizes brassy yellow tones and helps keep color-treated blonde hair looking cool and shiny between salon visits.

Formulated with violet pigments plus botanical extracts like fig and orchid, this toning shampoo lowers hair pH while gently cleansing and conditioning. Instead of stripping color, it deposits a calibrated hint of purple pigment to counteract warmth, leaving hair smoother and with renewed cool dimension. The formula is vegan, paraben-free, and designed to work as part of the Color Last system alongside the matching conditioner.

How does a purple shampoo actually neutralize brassiness?

Purple pigments sit opposite yellow on the color wheel, so they visually cancel out unwanted yellow and orange tones that appear in lightened, highlighted, or gray hair. This shampoo deposits violet color in small amounts while cleansing, which refreshes cool tones without changing your base color dramatically.

• Contains violet pigments that temporarily tone yellow/orange tones.
• Low pH helps seal the hair cuticle for color longevity and shine.
• Use 1–2 times weekly or as needed to maintain chosen brightness.
• Works best with the Color Last Conditioner to balance hydration.

Will it dry out or damage color-treated hair?

Biolage ColorLast Purple Shampoo is formulated to both tone and condition, so it aims to cleanse without excessive stripping. The product’s botanical base and conditioning agents help maintain softness and reduce breakage compared with non-conditioning purple formulas.

• Infused with fig and orchid extracts for conditioning benefits.
• Reported to leave hair up to 2.5x smoother with reduced breakage.
• Vegan and paraben-free formulation avoids harsh sulfates and ingredients.
• Follow with Color Last Conditioner to restore moisture and manageability.

How should I use it for best results and how often?

Apply the shampoo to wet hair, lather, and rinse; frequency depends on your hair’s porosity and how quickly brass develops. For most blondes, once or twice a week is enough—use less often on porous or pre-lightened hair to avoid over-toning.

• Wet hair thoroughly before applying to ensure even pigment distribution.
• Lather and leave on for 1–3 minutes for subtle toning; longer for stronger correction.
• Rinse well and follow with Color Last Conditioner to seal the cuticle.
• Adjust frequency based on color results and hair condition.

Can all shades of blonde use ColorLast Purple Shampoo?

Yes—this product suits many blonde shades, from natural to highlighted to platinum, and can also be used on gray or silver hair that shows yellowing. Results vary by starting tone: lighter, cooler bases will see subtler effects, while brassy or yellowed hair benefits most from the violet pigments.

• Effective on highlighted, plated, or all-over blonde and gray tones.
• Stronger toning effect on warmer, brassy hair; use cautiously on delicate or porous strands.
• Combine with the Color Last system for consistent color maintenance.
• Patch-test first if you have previously colored or chemically treated hair.

Who is this for: Biolage ColorLast Purple Shampoo is made for people with color-treated blonde, highlighted, or gray hair who want to reduce unwanted warmth between salon visits while keeping hair conditioned. It’s a good option for those seeking a gentle, botanical-forward formula that supports color vibrancy without animal-derived ingredients or parabens. If you need intensive color correction or a permanent change, consult your stylist; for routine brass control and added shine, this shampoo is a quick at-home maintenance step.
