Pyrithione Zinc is a coordination complex of zinc with fungistatic and bacteriostatic properties. In fact, it is best known for its use in treating dandruff and seborrhoeic dermatitis, particularly in dandruff shampoos. Besides, Pyrithione Zinc also has antibacterial properties and is effective against many pathogens. Its other medical applications include treatments of psoriasis, eczema, ringworm, fungus, athletes’ foot, dry skin, atopic dermatitis, tinea, and vitiligo. It is worth noting that Pyrithione Zinc’s antifungal effect is thought to derive from its ability to disrupt membrane transport by blocking the proton pump that energizes the transport mechanism. Remember to call your doctor or get medical help if the use of Pyrithione Zinc shampoo causes irritation. You also need to tell your doctor if you are pregnant or plan on getting pregnant, because you will certainly need to talk about the benefits and risks of using pyrithione zinc shampoo while you are pregnant
