How Ketonase Soap works

Ketonase Soap is a combination of two antifungal medicines: Ketoconazole and Zinc pyrithione. It works by destroying the cell membrane of fungi that cause dandruff. Ketoconazole works by breaking down the cell membrane of fungi, effectively killing them, while zinc pyrithione controls fungal growth and reduces irritation, redness, and flaking. Together, they combat fungal infections, soothe the affected area, and prevent recurrence, promoting healthier skin and scalp. Use as directed for best results.
