Pureology Strength Cure Shampoo is a rich, repairing cleanser that helps restore fragile, damaged hair.
This creamy, sulphate-free formula gently lifts away dirt while protecting colour-treated strands. As you lather, it feels silky and cushiony, with a light, clean scent that makes washing your hair feel like a small daily ritual.

Ideal for brittle, over-processed, or heat-styled hair, it’s best used whenever you wash, especially after colouring or bleaching. Hair feels smoother, more resilient, and easier to comb, with a soft, healthy-looking finish that moves naturally.

- Apply a small amount of shampoo to your scalp and roots.
