Ketwon Shampoo is a medicated topical formulation containing Ketoconazole 2% and Zinc Pyrithione 1%, designed for the effective management of dandruff and seborrheic dermatitis. Ketoconazole, an imidazole antifungal agent, exhibits broad-spectrum activity against dermatophytes and yeasts by inhibiting ergosterol synthesis, thereby disrupting fungal cell membrane integrity. Zinc Pyrithione complements this action with its antibacterial and antifungal properties, reducing scalp flaking, itching, and inflammation. Ketwon Shampoo is indicated for the treatment of scalp conditions characterized by scaling, redness, and itching, including dandruff and seborrheic dermatitis. The combination of these active ingredients provides a synergistic effect that helps restore the scalp’s natural balance and prevents fungal proliferation. For optimal results, it is recommended to apply the shampoo to wet hair, massage gently into the scalp, leave on for 3-5 minutes, and rinse thoroughly. Use frequency may vary depending on severity, typically 2-3 times weekly. Ketwon Shampoo is generally well tolerated; however, mild irritation or dryness may occur in some patients. It is contraindicated in individuals with known hypersensitivity to ketoconazole, zinc pyrithione, or any formulation components. Avoid contact with eyes; if contact occurs, rinse thoroughly with water. Consult a healthcare professional before use in pregnant or breastfeeding women.
