I had the same problem. one day I realized the oil in my hair depends on my food intake. In particular, for me it has a huge correlation with the "glycemic index": http://en.wikipedia.org/wiki/Glycemic_index http://en.wikipedia.org/wiki/Glycemic_index Chocolate is the biggest scalp hair oil producer of all. For me it is incredible how fast it goes from my stomach to my hair, I feel my hair grease within hours!! of eating it. The same could be said about acme and skin pimples. If instead of Chocolate I eat Apples or even sugar fruits like plums, I have no such a problem. It has to be something like the fiber controlling the sugar released on blood per second or something.
