Just like with other pets in your home, you cannot use human shampoos on your ferret. Containing strong chemicals that can severely irritate your ferret’s fur and skin, bathing your ferret in any human product should be strongly avoided.  When bathing any pet is it imperative to only use shampoos specifically designed to suit that pet's needs and requirements. As our hair and skin are adapted differently to our furry counterparts, as we wouldn’t wash our hair with their shampoo, why wash theirs with ours.
