Alpecin Shampoo Caffeine C1 is a shampoo that promotes hair growth and effectively reduces hair loss. This shampoo is very suitable for daily use. The caffeine present penetrates the hair and works even further if the hair has already been rinsed out. The shampoo only takes 120 seconds to properly care for your hair. Allowing it to work longer ensures that the scalp is also cared for. After only a few washes, the hair structure will be improved and fine and dull hair will be stronger and easier to style.
