Alpecin German Caffeine Shampoo
The shampoo that stimulates hair growth directly at the roots. A daily hair wash with C1 immediately provides the hair roots with the activating ingredient.
Alpecin Caffeine is very well detectable after being left on for as little as 120 seconds. If left on for longer, more caffeine will be absorbed into the scalp.
Men's skin is more sensitive than women's skin. This is due to the male hormone testosterone - it makes men's skin less robust and weakens its natural protective function significantly. For the scalp, this means that it loses moisture, its cells regenerate too slowly and both skin and hair roots age prematurely, thereby accelerating hair loss.
Information for Competitive Athletes: Alpecin Caffeine Shampoo can be detected in hair follicles.
