What Zinc Pyrithione does
- Reduces yeast on the scalp
- Helps reduce visible flaking
- Adds mild antibacterial action
Zinc pyrithione is a man-made compound, formed by combining pyrithione with zinc. Formulators choose it because it works against Malassezia, a yeast that lives on most scalps and is linked to flaking. It also has mild antibacterial action.
It does not dissolve in water, so it sits in shampoo as fine particles that spread over the scalp during washing. Shampoos with it often look pale or slightly opaque. It is a rinse-off product, so it is meant to stay on the scalp only for the short time a shampoo is worked in before rinsing.
Good for
People with flaky or itchy scalp who want a rinse-off shampoo with an anti-dandruff active.
