benefits

Piroctone Olamine is a popular ingredient in hair care products that treat dandruff and other scalp conditions. Controls dandruff: Piroctone Olamine is effective at controlling the growth of Malassezia, a yeast that can contribute to dandruff and other scalp issues. By controlling the growth of this yeast, Piroctone Olamine can help to reduce or eliminate dandruff. Soothes the scalp: Piroctone Olamine has moisturizing properties that can help to soothe and hydrate the scalp. This can help prevent dryness, flakiness, and itching, common symptoms of dandruff and other scalp conditions. Safe for coloured hair: Piroctone Olamine is safe for use on coloured hair and will not cause fading or strip colour. Prevents fungal growth: Piroctone Olamine not only controls the growth of Malassezia, but it also prevents the growth of other fungi that can cause scalp problems. Long-lasting effect: Piroctone Olamine has been shown to have a longer-lasting effect than some other dandruff-fighting ingredients, meaning you may be able to go longer between washes. Gentle on the scalp: Piroctone Olamine is gentle on the scalp, making it suitable for sensitive skin.

Mechanism of action

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.

Side effects

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.
