No Orange Shampoo is suitable for coloured hair with orange tinges and dark shades. It gently cleanses and neutralises undesired copper/red reflections, leaving the hair more shiny and hydrated. This shampoo is best used as a pre-toner in the basin before applying toner. Simply wear protective gloves to avoid standing your fingers, apply to wet hair, massage and leave on the hair for 1-5 minutes, lather and rinse. Repeat this application. Take caution when using on bleached or lightened hair as it can overtone. It does not stain the scalp.
