The first Alpecin shampoo with 4 active ingredients. Together they remove dandruff, relieve scalp irritation and form a powerful anti-dandruff defence system. The 4 active ingredients are: - **Salicylic acid** and **fumaric acid**. These help to remove existing dandruff and create a smooth scalp surface, reducing the colonization of microorganisms in a sustained manner. - **Zinc pyrithione** and **piroctone olamine**. Effective against fungi, yeast and bacteria. This prevents new dandruff and restores the scalp’s natural balance. In addition, panthenol, allantoin and a sophisticated galenic formula prevent irritation and stabilize the scalp’s resistance. Suitable for daily use against dandruff.
