Shampoo tailored for the beard Facial hair differs from the hair on your head. Your scalp is producing way more natural oils than your face, so most facial washes are designed to deal with that high level of oil. Your face isn't nearly as oily, and washing it with regular shampoo dries out your facial hair and the skin underneath. The beard wash cleanses your beard and skin from dirt, and bacteria while still keeping it moisturized afterward.
