Xampu KZ Anti‑Dandruff Shampoo contains ketoconazole, which treats dandruff and scalp infections. It is not safe for a 3‑month‑old baby because its safety and effectiveness have not established in infants. Medicated anti‑dandruff shampoos are not recommended for very young children due to sensitive skin. For a 3‑month‑old with scalp flakes or cradle cap, gentle baby shampoo or mild oils are preferred, and treatment should be guided by a paediatrician.
