Exizol Anti-dandruff Shampoo (Ketoconazole) helps reduce dandruff by killing the fungus on the scalp that causes flaking and itching. It also helps in conditions such as seborrhoeic dermatitis (dry and flaky skin on the face, scalp, or chest) by calming irritation and controlling scaling. It is generally suitable for very oily hair, as it helps control excess oil by reducing underlying scalp fungal overgrowth. It should be used as directed on the label or as advised by a doctor to avoid scalp dryness or irritation.
