This shampoo has been created for brunette hair, featuring green pigments that counteract & neutralise red tones in the hair. The result is a cooler & more natural-looking brunette colour. It is ideal for brown, chestnut, & auburn hair that is natural, coloured, or bleached. To use: After shampooing normally, apply to the hair & work into a lather. Leave for 1-3 minutes before rinsing thoroughly.
