What shampoo should be used for an oily dandruff hair ?!

SO many ones: Find a good shampoo for oily hair and lather up with your fingernails scratching your head. This will remove a lot of the dead skin of the scalp that causes dandruff. Shampoos with selenium sulfide seem to help a lot of people. There is, however, no true cure.

Head ; Shoulders: Try head ; shoulders first. If it does not resolve, get an evaluation by a dermatologist.
