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.
But there are also other reasons for men to really like this shampoo. Thanks to the intentional omission of softeners (e.g. silicone), the hair structure improves after just a few hair washes with enhanced hair grip. Fine and weakened hair becomes stronger and can be styled better.
