The Plantur 39 Colour Brown Phyto-Caffeine Shampoo results in a deeper brown and greater colour brilliance with each wash. Annoying greys and light roots are covered. Coloured pigments build up on the hair with each wash to increase the colour intensity over time. At the same time, activating phyto-caffeine penetrates into the hair follicles where it helps to prevent menopausal hair loss. The result: Amazingly beautiful hair.
