Pureology Strength Cure Blonde Purple Shampoo for Blonde & Lightened Hair, 9 fl oz — Sulfate-Free Toner + Strengthening

Formulated for bleached, highlighted and naturally blonde hair, this purple shampoo combines pigment-rich toning with reparative botanicals. It layers cool purple pigments to neutralize yellow and orange brassy tones, while Keravis plant-based protein and antioxidant Astaxanthin help strengthen and rebuild over-processed strands. The vegan, sulfate- and paraben-free formula is designed to be used as part of a maintenance routine to keep blonde shades bright and resilient between salon visits.

How quickly will I see toning results?

Toning begins immediately on contact: purple pigments deposit as you lather and will visibly reduce unwanted warmth after the first use for many users. The intensity depends on how long you leave the product on and the starting shade of your hair.

• Warm blondes: leave 1–3 minutes for subtle neutralizing.
• Neutral blondes: leave 3–5 minutes for balanced toning.
• Cool blondes or heavy brass: leave 5–15 minutes for stronger correction.
• Repeat washes for deeper toning or mix with conditioner for milder effect.

Will it repair damage from lightening?

While primarily a toning shampoo, the formula also supports hair repair. Keravis (a plant-based protein) and Astaxanthin work alongside the Strength Cure base to fortify weakened cuticles and help reduce breakage over repeated use.

• Keravis adds protein to strengthen strands and improve elasticity.
• Astaxanthin supplies antioxidant support to help protect and repair.
• Regular use with the Strength Cure conditioner enhances results.
• Sulfate-free cleansing avoids additional drying of lightened hair.

How should I use it to avoid over-toning?

Apply a dime- to quarter-sized amount to wet hair, emulsify into a lather, and focus on mid-lengths to ends where brassy tones concentrate. Rinse according to desired toning strength and follow with a nourishing conditioner.

• Start with shorter processing times and increase only if needed.
• Use once or twice a week depending on brassiness and color maintenance.
• Combine with Strength Cure Best Blonde Conditioner to lock in tone and moisture.
• Patch-test on a small section if you’re using it for the first time.

Is it safe for color-treated hair and suitable for daily use?

Yes—this shampoo is formulated specifically for color-treated hair and is free of sulfates and parabens, making it gentler than many standard clarifying shampoos. However, purple shampoos are typically used intermittently rather than every day to avoid over-depositing pigment.

• ZeroSulfate formula protects salon color from harsh stripping.
• Vegan, paraben-free ingredients align with cleaner beauty preferences.
• Use weekly or as needed; daily use may deepen cool tones.
• Follow with a hydrating conditioner to preserve softness.

Who this is for: Pureology Strength Cure Blonde Purple Shampoo is ideal for people with bleached, highlighted, grey, silver or natural blonde color who want to neutralize yellow/orange brass while improving hair strength. It suits those seeking salon-grade toning without sulfates—especially anyone with fragile, over-processed strands looking to maintain cooler, brighter blonde tones between professional color appointments.
