A shampoo that stimulates hair growth directly at
the roots. The caffeine in Alpecin products penetrates to the roots of the hair, even after washing the hair. In a relatively short time (120 seconds), the active substance reaches the hair follicle directly. If you leave the shampoo on, the caffeine will also reach the scalp. Dosage and method of use: The preparation is applied like a normal shampoo, by massaging it into the wet scalp and then rinsing with a sufficient amount of water.
