Our Classic Clean 2 in 1 shampoo, with a new HydraZinc formula, is even more active than before in fighting the source of dandruff at the first wash. It works against flakes as well as other related signs of dandruff - dryness, itchiness and a tight scalp. This pH-balanced shampoo leaves you with clean, manageable hair day after day, even on colour-treated hair.
