Colour Keeper Shampoo

Colour fades because water and surfactants open the cuticle. This cleanses at a lower pH and closes it again on the way out, which slows the fade considerably.

pH-balanced surfactant system, UV filter, sunflower seed extract, vegetable-derived cationic polymer.

Use from the first wash after colour. Rinse cooler than feels natural — heat is what opens the cuticle again.

Colour retention measured 2.3x longer than a standard shampoo over twelve washes.
