Stumbled across this doing my weekly shop, 3 for 2 on a lot of toiletries but this seems a decent deal.
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.

How does Alpecin work?
Alpecin Caffeine penetrates even though the shampoo is rinsed out. In just a short time (120 sec.), caffeine 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. This shampoo does not contain any conditioning agents so your hair will immediately have more grip.
Leave on the scalp for 2 minutes, from application to rinse. By intentionally doing without softeners (e.g. silicone), your hair will immediately have more grip.
