How long does the colouring effect of the Plantur 39 Colour Silver products last?
The Plantur 39 Colour Silver products contain powerful violet pigments that build up on the hair. These build up on the hair. The colouring effect intensifies every time you wash your hair and can be washed out gradually with a conventional shampoo. As such, Plantur 39 Colour Silver products have to be used regularly in order to achieve the desired colour effect and reduce the unwanted yellow hue in the long term. Leave the products on for 2 to 5 minutes depending on the desired colour intensity. Then rinse out thoroughly.
