Pureology Strength Cure Shampoo for Damaged or Color-Treated Hair, 33.8 fl oz — Sulfate-Free, Vegan Repair & Color Protection

Pureology Strength Cure Shampoo is a sulfate-free, vegan shampoo formulated to repair damaged or color-treated hair, reduce breakage, and seal split ends while preserving color vibrancy.

Built for hair weakened by chemical services, heat styling, or everyday stress, this concentrated formula is part of Pureology’s Strength Cure system. It pairs gentle cleansing with advanced anti-breakage technology to strengthen strands and improve manageability without stripping color. The large 33.8 fl oz size is ideal for at-home use or salon backbar needs.

How does this shampoo rebuild strength in damaged hair?

The shampoo uses targeted repair technology to fortify the hair fiber and reduce breakage over time. While gentle surfactants cleanse, conditioning agents and strengthening ingredients work to restore elasticity and resistance to snapping.

• Formulated to restore up to 99% of hair’s virgin strength when used within the Strength Cure regimen.
• Concentrated formula requires less product per wash for effective cleansing and repair.
• Sulfate-free surfactants protect color and avoid the harsh stripping action of traditional detergents.

Will it keep my color looking fresh and vibrant?

Yes—this shampoo is specifically color-safe and crafted to preserve dyed hair’s tone and shine. The mild formulation limits color fade caused by aggressive cleansing while adding glossy, conditioned finish.

• Zero-sulfate cleansing helps retain salon color between appointments.
• Moisture-balancing agents reduce dullness and enhance surface shine.
• Safe for frequent use on color-treated hair without compromising pigment.

Can it help with split ends and everyday breakage?

Pureology Strength Cure Shampoo is designed to seal and smooth split ends while reducing the rate of new breakage. Regular use improves texture so hair looks and feels healthier, though professional trimming is still recommended for very damaged ends.

• Ingredients target the cuticle to minimize frizz and prevent further splitting.
• Strengthening actives increase strand flexibility to reduce snapping under tension.
• Works best combined with the matching Strength Cure conditioner and treatments for visible results.

How does the vegan, sulfate-free formula affect daily styling and scalp comfort?

The clean, plant-friendly formulation balances effective cleansing with a comfortable scalp feel and improved styling performance. It removes dirt and product build-up without leaving hair dry, supporting smoother blowouts and longer-lasting styles.

• Vegan formulation avoids animal-derived ingredients and common harsh detergents.
• Gentle lather rinses clean without overdrying, aiding comb-through and styling.
• Suitable for fine to medium hair types; concentration helps extend usage on thin hair.

Who is this for: Pureology Strength Cure Shampoo is aimed at anyone with weakened, chemically processed, or heat-stressed hair who wants to rebuild strength while keeping color intact. It’s appropriate for clients and consumers seeking salon-quality repair in a large, economy-sized bottle—especially those committed to a matching Strength Cure routine for best results.
