Maintain your hair's colour for longer with the Redken Colour Extend Magnetics Deep Attraction Mask, a colour-locking treatment that will extend the life of coloured hair. The sulphate-free hair mask uses zinc gluconate, known for its colour retention properties, to attract colour molecules and trap them into hair fibres. The mask also uses Redken's signature IPN technology to strengthen the hair's fibres and preserve the richness of your colour, leaving the hair feeling softer and smoother. A must-have for colour-treated hair, this pampering mask will prevent colour fade and keep hair looking and feeling as fresh and vibrant as it did on day one. Apply to clean, wet hair. Leave in for 5 to 15 minutes depending on the condition of the hair. Rinse. Can be used weekly or daily if needed. If contact with eyes occurs rinse immediately.
