Basically, i have been suffering from excessive oil production on my entire head, face, ears, and back. When these areas are wet with warm water, i have been scratching them off with nails and i get huge amounts of a whitish yellowish oily paste in my fingernails. This can occur multiple times a day. Ive been using ketoconazole shampoo prescribed but it only leaves my head clean for a few hours at most. I just want to live a life without an oily face and head every second
