DANFRO SHAMPOO is used to control dandruff, itching and flakiness. Studies show that, Salicylic acid helps rid patient's scalp off dry skin and dandruff, which means reduced itchiness and irritation. It's effective at treating dandruff, seborrheic dermatitis, and psoriasis. Ketoconazole shampoo is often more effective and, as a result, is used for more severe cases of itching and flakiness.
