Pureology purple shampoo for blonde & lightened hair — 33.8 fl oz Strength Cure, sulfate-free toning & strengthening

Pureology Strength Cure Blonde Purple Shampoo is a sulfate-free, color-depositing cleanser that tones brass, strengthens lightened hair, and helps maintain salon-fresh blonde between appointments.

Designed for blonde, highlighted, grey or silver color-treated hair, this 33.8 fl oz professional-size shampoo blends concentrated purple pigments with repairing ingredients to neutralize yellow and brassy tones while supporting fragile, over-processed strands. The formula pairs Pureology’s AntifadeComplex with Keravis plant-based protein and the antioxidant Astaxanthin to reinforce weakened hair and preserve color vibrancy without sulfates, parabens, or animal-derived ingredients.

How does this shampoo neutralize unwanted brassiness?

The shampoo deposits cool purple pigments that counteract warm yellow and orange undertones in blonde and lightened hair. Depending on the shade and porosity, the pigments sit on the hair surface to visually cancel brass, leaving a cleaner, cooler blonde after rinsing.

• Blue-based purple pigments target yellow and orange brass.
• Adjustable timing (1–15 minutes) controls intensity of toning.
• Use weekly or as needed to refresh cool tones between color appointments.

Will it repair and strengthen hair damaged by lightening?

Yes—this Strength Cure variant combines structural support and antioxidants to help mend and fortify weakened strands. Keravis helps reinforce fiber integrity while Astaxanthin provides antioxidant support that contributes to a more resilient appearance.

• Keravis plant-derived protein strengthens stressed cuticles.
• Astaxanthin antioxidant helps protect and support repair.
• Regular use in the Strength Cure system helps reduce breakage and improve manageability.

How should I use it to get the best toning results?

Apply a small amount to wet hair, lather at the roots, and work through to the ends—leaving it on controls how much tone is deposited. Shorter times give a subtle cool-down; longer times create a stronger neutralizing effect. Rinse and follow with the companion Strength Cure Blonde Conditioner for conditioning and continued tone maintenance.

• Use a quarter- to dime-sized amount depending on hair length and thickness.
• Timing guide: 1–3 minutes for warm blondes, 3–5 for neutral blondes, 5–15 for cool blondes.
• For stubborn brassiness, repeat or leave on longer as needed.

Is this product safe for color-treated hair and suitable for my haircare routine?

Formulated with Pureology’s AntifadeComplex, the shampoo is gentle on professionally colored hair and helps protect color longevity. It’s sulfate-free and vegan, making it compatible with most color-preserving routines, and pairs well with the Strength Cure Blonde Conditioner for balanced toning and repair.

• Sulfate-free and paraben-free to minimize color stripping.
• Vegan formulation safe for color-treated strands.
• Best used alongside Pureology Strength Cure Blonde Conditioner for full results.

Who is this for: This shampoo is made for people with lightened, highlighted, platinum, grey or silver hair who want to reduce yellowing and strengthen delicate, over-processed strands. It suits salon clients and at-home users who need a professional-size toning shampoo that combines pigment deposition with reparative ingredients—especially those seeking sulfate-free, vegan options to support color longevity and hair resilience.
