How do you treat your hair if the top of your head is oily but not the rest of your hair?

I had the same problem. What you do is DO NOT use a moisterizing shampoo! It'll jut make it not look clean at the top of your head. Instead find a non-moisterizing clerifying shampoo. (you can find one made by "Ion" at Sally Beauty Supply)

Also, don't put conditioner on the top of your head. Using it from about your ears length down to the tips.

Both tips will help keep the oil undercontole.

(Also, if you find that one day in the morning it is looking a bit oily, but you have no time to take a shower, dry shampoo worls aswell.)
