This Alpecin Caffeine Shampoo provides essential nutrients directly to the hair roots with every use throughout the day. Leaving it on ensures maximum absorption into the scalp for better effectiveness.
Using Alpecin Caffeine shampoo daily provides the hair roots with the active ingredient. It is recommended to leave the shampoo on the hair for at least two minutes so that all the caffeine can be absorbed into the scalp. The longer it is left the more caffeine can be absorbed.
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.
