Pureology Strength Cure Blonde Purple Shampoo 33.8 fl oz — sulfate-free toning, reparative for blonde & lightened hair

Pureology Strength Cure Blonde Purple Shampoo is a sulfate-free, color-depositing cleanser that tones brassiness while helping to strengthen and repair lightened, blonde, and silver color-treated hair.

This concentrated 33.8 fl oz salon-sized formula combines purple toning pigments with Pureology’s AntifadeComplex plus plant-based Keravis protein and antioxidant Astaxanthin to neutralize yellow/orange tones and support fragile, over-processed strands. The product is vegan, paraben-free, and formulated to maintain color vibrancy between salon visits while delivering restorative benefits.

How does this shampoo remove brass and restore cool blonde tones?

The shampoo deposits blue-based purple pigments that counteract warm yellow and orange undertones, brightening pale, silver and platinum shades. It works during the short rinse window to adjust tone without stripping color because it’s a ZeroSulfate formula designed for color-treated hair.

• Deep purple pigments neutralize brassy warmth in blonde, grey, and silver hair.
• AntifadeComplex helps protect color molecules from fading.
• Sulfate-free base cleanses without harsh surfactants that can strip dye.

Will it help repair damaged or over-processed hair?

Yes — Strength Cure Blonde uses reparative ingredients to reinforce weakened fibers while toning. Keravis, a plant-derived protein, helps strengthen the hair shaft and reduce breakage, while Astaxanthin provides antioxidant support to help hair feel healthier over repeated use.

• Keravis protein strengthens and helps prevent future damage and breakage.
• Astaxanthin supports strand resilience and overall hair condition.
• Formulated to pair with the Strength Cure conditioner for additional repair and hydration.

How should I use this purple shampoo for best results?

Apply a quarter-sized amount to wet hair and emulsify, focusing on areas with brassiness. Leave the shampoo on according to your desired tone: shorter for warm blondes and longer for cooler or more neutral shades; always rinse and follow with conditioner.

• Warm blondes: leave 1–3 minutes; neutral blondes: 3–5 minutes; cool blondes: 5–15 minutes.
• Use a dime-to-quarter sized amount depending on hair length and porosity.
• Rinse thoroughly and follow with Strength Cure Blonde Conditioner for balanced hydration and continued toning benefits.

Is this shampoo safe for colored hair and suitable for professional use?

Designed for color-treated hair, the formula is salon-quality and trusted by stylists for toning and maintenance. It’s vegan, paraben-free, and formulated without sulfates to help prolong salon color while delivering targeted toning and repair.

• ZeroSulfate and paraben-free — safe for most color processes when used as directed.
• Concentrated formulation ideal for salon or at-home maintenance.
• Pairs with other Pureology Strength Cure products to extend color life and improve hair condition.

Who is this for: Pureology Strength Cure Blonde Purple Shampoo is aimed at people with blonde, highlighted, lightened, grey, or silver color-treated hair who want to reduce brassiness while improving hair strength. It’s a practical choice for anyone seeking salon-grade toning and repair in a vegan, sulfate-free formula — especially those with fragile, over-processed strands who follow up with a conditioning treatment for best results.
