    Sulfur is a natural powerhouse for fighting acne, dandruff, and fungal infections. It helps regulate sebum production and reduce irritation.
    Salicylic Acid gently exfoliates, unclogs pores, and removes dead skin cells, leaving skin smooth and refreshed.
    Herbs like sage, rosemary, chamomile, and horsetail provide antioxidants, anti-inflammatory benefits, and hydration.
    Lauryl Glucoside is a mild detergent that cleans without stripping natural oils, making it suitable for sensitive skin and scalp.
