Will I need to use the Double-Effect Caffeine Shampoo in the long term?

Basically yes. Due to the product's dual action, i.e. the simultaneous effect against dandruff and hair loss, the shampoo prevents premature hair loss and removes annoying dandruff. Both are long-term causes which means that the hereditary predisposition as well as the risk of skin irritation and dandruff due to microorganisms and sebum will remain for life.
