Caffeine promotes hair growth. It has even been proven to slow down hereditary hair loss. Now you can transport this unique active ingredient to the hair roots during daily hair washing.
Alpecin Caffeine penetrates even though the shampoo is rinsed out. In just a short time (120 sec.), the active ingredient travels along the hair shaft directly into the hair follicles. If the shampoo is left on for longer, the caffeine will also penetrate into the scalp.
