I have the same problem with my hair, I also get bad Acne and itchy scalp and sometimes spots on top.. I managed to get rid of the dandruff using nizoral shampoo but it still hasn't stopped my hair looking dead and getting overly greasy.. my body is definately out of balance due to anti-biotics and i am trying hard to rectify it by cleansing and de-toxing.. just wish it didn't get worse before getting better.
