Matrix Colour sync Vivid Violet demi-permanent hair colour provides a uniform colour and even coverage of grey hair. Formulated with 2x the ceramides, it fills damaged gaps in the hair fibre to create bold, rich, full-bodied look. This ammonia-free hair colour slightly penetrates the hair shaft. The long-lasting formula with cera-oil also offers more conditioning. Hair is toned and polished and perfectly smooth with rich reflects from roots to ends.
