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 & trap them into hair fibres. The mask also uses Redken's signature IPN technology to strengthen the hair's fibres & preserve the richness of your colour, leaving the hair feeling softer & smoother. A must-have for colour-treated hair, this pampering mask will prevent colour fade & keep hair looking & feeling as fresh & 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.
