The Piroctone olamineor octopirox (in Latin: piroctone olamine) is an active substance effective against parasitical fungi, molds, bacteria and yeasts., particularly Malassezia furfur yeasts, which commonly exist on the human skin surface. If the yeast breaks out, the skin is irritated, which results in dandruff formation or other skin diseases.
Octopirox is a very effective substance with a wide antifungal spectrum (particularly in Malassezia yeasts) which is also demonstrated by in vitro study 1.2 (the effect of octopirox, which inhibits growth of Malassezia yeasts already at a concentration of 63 μg/ml) shown in the Figure below. Piroctone olamine is also effective against an excess of bacteria (various types).
Octopirox is effective only as long as one washes his/her hair. It is therefore necessary to make the product and its contents work for 3-4 minutes.
