The world's first shampoo against dandruff and hereditary hair loss - alpecin double-effect shampoo.a very long time ago, sebum was meant to waterproof the hair and skin and protect humans from the cold. Since humans wear clothes, this function has become superfluous. In addition, germs and microorganisms that naturally occur on the skin use sebum as a source of nutrition. Degradation products of sebum irritate the skin, make it itch and accelerate the formation of the keratinous layer. The consequence is dandruff. Due to subsequently released sebum, these skin cells stick together to form large, visible skin flakes.based on an excess of testosterone, which begins during puberty, hair may fall out prematurely. As a result, many men notice hereditary hair loss early on. The hair root is hypersensitive to the hormone dihydrotestosterone (dht). It weakens the hair roots and prematurely renders them inactive. This shortens their growth phases and terminates their lifetime prematurely. If more and more hair roots die in this manner, baldness will ensue.
