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. 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 if necessary. For more brassy tones, use in dry hair for 15 minutes.Take caution when using on bleached or lightened hair as it can overtone. It does not stain the scalp.
