The Plantur 39 Colour Silver Phyto-Caffeine Shampoo gives an elegant silver sheen to bleached and grey hair with each wash. The unwanted yellow hue is reduced and the hair colour gradually turns cooler and more silvery. Strong, violet pigments build up on the hair with each wash, increasing the colour intensity over time. At the same time, activating caffeine penetrates into the hair follicles where it helps to prevent menopausal hair loss . The result: Amazingly beautiful hair, even over the age of forty.
