Piroctone olamine, also known as Octopirox, is an antifungal and antibacterial agent commonly used in cosmetic and personal care products, such as shampoos, conditioners, and lotions. It works by inhibiting the growth of various microorganisms, including yeasts and fungi, by disrupting their cell membranes and interfering with their metabolism. Specifically, piroctone olamine targets the enzymes responsible for synthesizing the cell membrane of microorganisms, inhibiting their growth and causing their eventual death. It also has anti-inflammatory properties that help to reduce redness and itching on the scalp and skin.
It should be kept in mind that shampoos with Piroctone Olamine should not be used more than twice a week, unlike other daily-use shampoos that don't have this ingredient. One of the biggest side effects of Piroctone Olamine is that it can cause irritation and itchiness on the head.
