Caffeine promotes hair growth. It has even been shown to slow down hereditary hair loss. Now you can transfer this unique active ingredient to the hair roots during your daily hair wash. The caffeine in Alpecin penetrates even though the shampoo is rinsed off. In a short time (120 seconds), the active ingredient travels along the hair shaft directly to the hair follicle. If the shampoo is left in for a longer period, the caffeine will also penetrate into the scalp. But there are also other reasons why men really love this shampoo. Based on the deliberate omission of conditioners (such as silicone), the hair structure improves after just a few washes while enhancing the hold of the hair. Thin, weak hair becomes stronger and can be styled better.
