Piroctone Olamine for Dandruff

Hairetic's preferred Anti-Dandruff active agent, and the perfect combination of performance and protection for senstive skin. Piroctone Olamine is a great option for helping to prevent dandruff with the minimum side effects.

What Is Piroctone Olamine?

Piroctone Olamine is an antifungal and antibacterial agent used in shampoos and scalp treatments. It impairs the cell membrane of Malassezia yeast—one of the main causes of dandruff—by inhibiting ergosterol synthesis and disrupting cell metabolism (Wikipedia).

Why Choose Piroctone Olamine Over Zinc Pyrithione?

  • Piroctone Olamine is safer to use: The EU banned Zinc Pyrithione in March 22 after classifying it as a Category 1B reproductive toxicant. Whilst it can be effective, the EU ban focused on less toxic alternatives being available (such as Piroctone Olamine) (Official EU Regulation)
  • Comparable or better efficacy: Clinical studies show 0.5% piroctone olamine + climbazole matched the dandruff‑fighting power of 1% zinc pyrithione shampoos, with improved scalp condition and itch reduction (PubMed study).
  • Gentler on scalp & hair: Unlike zinc pyrithione’s harsher action, piroctone olamine avoids over‑drying or degreasing, preserving scalp microbiome and hair strength.
  • Formulation‑friendly: Stable across pH 3–9, easily incorporated in leave‑on products without destabilizing surfactants.
  • Environmentally responsible: Less toxic to aquatic life and breaks down efficiently—especially compared to zinc pyrithione, which is now restricted in the EU.

Benefits of Piroctone Olamine

  • Highly effective antifungal action against Malassezia
  • Moisturises and soothes itching or dryness
  • Safe for coloured and chemically‑treated hair

Is it safe for daily use?

Yes—formulations typically use 0.3–1.0% concentrations, and daily or alternate‑day use is fine for most users.

How long until I notice improvement?

Itching and flaking often diminish within 2–4 weeks. In comparative trials, users reported a 90% reduction in scalp itching after 4 weeks (PubMed study).

Will it work on color‑treated hair?

Yes—it does not strip dyes or alter colour‑treated strands.

Is it suitable for sensitive scalps?

Absolutely—low irritation potential makes it ideal for sensitive or reactive skin.

How does it compare with ketoconazole or selenium sulfide?

Depending on formulation, it can be as mild and effective as ketoconazole or selenium sulfide, without harsh side effects.
