Pureology Strength Cure Shampoo & Conditioner Duo 266ml

If your hair has become weak, brittle, dry or damaged from colour treatments, bleaching or regular heat styling, the Pureology Strength Cure Duo provides a complete strengthening and conditioning routine.

The shampoo gently cleanses without sulfates while the conditioner helps restore softness, smoothness and manageability.

Pureology describes the Strength Cure Shampoo and Conditioner system as delivering 2× stronger strands compared with a non-conditioning shampoo in an instrumental test.

Rather than treating shampoo and conditioner as separate products, this duo gives you a coordinated routine designed specifically for damaged, colour-treated hair.

What Does Pureology Strength Cure Duo Do?

The Strength Cure system is designed to address common signs of hair damage, including:

• Hair breakage
• Weak-feeling strands
• Dryness
• Rough texture
• Loss of softness
• Hair affected by heat styling
• Chemically processed hair
• Colour-treated hair
• Hair that feels fragile or difficult to manage

The combination of strengthening and conditioning ingredients helps hair feel more resilient while improving its overall appearance and manageability.

Important: This is a cosmetic haircare system. It does not biologically repair or permanently reverse damaged hair from within the way a medical treatment would. Its benefits are focused on improving the feel, appearance and resilience of the hair fibre.

Key Ingredients & Hair Benefits

Keravis Protein

Keravis is a plant-based strengthening protein used in the Strength Cure formulas.

It helps support stronger-feeling hair and is particularly suited to routines designed for weak, damaged and breakage-prone strands.

For people searching for a Keravis protein shampoo for damaged or broken-looking hair, Strength Cure is specifically formulated around this strengthening technology.

Astaxanthin

Astaxanthin is a powerful antioxidant featured in the Strength Cure system.

Pureology positions Astaxanthin as an ingredient that helps support damaged hair and protect the hair fibre against environmental stress.

This makes it particularly relevant for hair exposed to everyday environmental aggressors, heat styling and chemical processing.

Antifade Complex®

Pureology's Antifade Complex® is designed to help protect colour-treated hair and maintain colour vibrancy.

This makes the duo particularly attractive if you regularly colour, highlight or chemically process your hair and want a strengthening routine that is compatible with your colour-care regime.

Arginine

Arginine is an amino acid included in the Strength Cure formulas.

Pureology identifies arginine as part of its ingredient system supporting stronger-feeling hair and elasticity.

Olive Fruit Oil & Camelina Seed Oil

The formulas also include oils such as olive fruit oil and camelina seed oil, helping contribute to softness, conditioning and a smoother-looking finish.

ZeroSulfate® Haircare

The Strength Cure Shampoo uses a sulfate-free cleansing system designed to gently cleanse damaged and colour-treated hair.

This makes it a strong option for shoppers specifically looking for:

sulfate-free shampoo for damaged colour-treated hair

or

sulfate-free shampoo for hair breakage and split ends.

The Strength Cure range is also positioned by Pureology as vegan and free from parabens and mineral oil.

Is Pureology Strength Cure Good for Damaged Hair?

Yes. Strength Cure is specifically formulated for damaged hair, including hair affected by colouring, heat styling and environmental stress.

The best frequency depends on:

• Colour-treatment schedule
• Heat-styling habits
• Scalp needs

For fine hair, start with a smaller amount of product, particularly when applying conditioner.

Concentrated Professional Haircare

Vegan Hair Repair Shampoo & Conditioner Set

The Strength Cure system uses vegan formulas without animal-derived products or by-products. Pureology also states that it does not test its products on animals.
