Alpecin Caffeine is working even though the shampoo is rinsed out. In just a short time (120 sec.), the active ingredient travels along the hair shaft where it unfolds its strengthening effect on the hair roots.
But there are also other reasons for men to really like this shampoo. Based on the intentional omission of softeners (e.g. silicone), the hair structure improves after just a few hair washes with enhanced hair grip. Fine hair becomes stronger and can be styled better.
(Information for competitive athletes: Alpecin Caffeine can be detected in hair follicles.)
