Answers to your questions
Do I have to use the double effect caffeine shampoo permanently?
In principle, yes. Thanks to the double effect, i.e. the simultaneous action against dandruff and hair loss, the shampoo prevents hereditary hair loss and gets rid of annoying dandruff. Both causes are permanent, i.e. the hereditary predisposition and the risk of skin irritation and dandruff caused by microorganisms and sebum persist throughout life.
What are the benefits of a scalp massage with the Alpecin Double Effect for hair loss?
By massaging the head with Alpecin Double Effect Caffeine Shampoo, the active ingredients are better absorbed by the skin and the hair roots and a supply of active ingredients (depot) is created. In addition, the gentle pressure removes the top cuticle layer more effectively.
