Does anyone know...

...of a really good shampoo for oily hair?  Seems all they make these days are things to put more moisture into your dry or damaged hair and that's the last thing I need.  Also, I would prefer something that doesn't volumize hair at all.  My hair is super thick as it is and does not need that kind of help.  I don't care about price so much as performance.  And if it's a salon type shampoo, where it is purchased at.  And if I'm allowed to be picky I would prefer either clear or white shampoo, nothing that has been dyed (but I'll take anything at this point).  Scented is okay.
