Ideal for use in between salon appointments, Redken's Root Fusion Duo blends seamlessly with hair to cover up dreaded roots, regrowth & grey hairs, leaving you feeling confident around the clock. With an innovative, easy-to-use formula, the lightweight, fast-drying spray utilises colour-concealing pigments that attach to individual strands for buildable coverage & a natural-looking, non-greasy finish. Suitable for all hair types, the root touch-up rinses out easily with shampoo.
