Noble Formula 2% Pyrithione Zinc (ZnP) Bar Soap - Hand Crafted in the USA Especially Formulated for Those with Psoriasis Eczema Dry and Sensitive Skin  (97.5 ml)

First i was using a diffrent brand, this one is more expensive but doesn't dry my skin that much. I use it for Seborrheic Dermatitis. Quantity is less when compared to price but if u are using it only on affected parts should last ling enough.
