Grevive Hue Hair Colouring Cream (Dark Brown) is a PPD & ammonia-free hair colouring cream designed to provide a rich dark brown shade with effective grey coverage while maintaining a smooth application experience, formulated with key ingredients such as Water, Cetearyl Alcohol, Ethanolamine, Toluene-2,5-Diamine Sulfate, Mineral Oil, Resorcinol, Propylene Glycol, and Amodimethicone that support colour development, consistency, and conditioning of the hair during the colouring process; the formulation is used by mixing the colour cream and developer in a 1:1 ratio, applying section by section starting from areas with more grey hair, allowing it to develop for 30–40 minutes, and then rinsing thoroughly followed by shampoo, making it suitable for achieving an even and consistent dark brown hair colour when used correctly.
