A weightless conditioning treatment that seals and protects the colour-treated hair shaft with every wash. A blend of colour-binding peptides, ceramides and an antioxidant-rich botanical complex locks in vibrancy, smooths the cuticle and enhances shine — without compromising lift or tone.

Apply to cleansed hair from mid-lengths to ends. Leave for two to three minutes and rinse. Ideal for use after Colour Preserve Shampoo as a complete colour care system.

Dermatologist tested. Sulphate and paraben free. Suitable for all colour-treated hair.
