Our soap dries very hard, which means a longer life for the bar. However, a bar of soap in the shower will get used up more quickly than a bar used strictly for hand washing. For hand washing, a bar can last up to two months. In the shower, the bar will last about 2-3 weeks. To extend the life of your bar of Pacha Soap, keep it out of direct contact with water and let the bar dry between uses.
