Have you tried using anti-dandruff shampoo or something? Maybe try Wen Tea Tree Formula.

Dandruff is actually a mild yeast infection. Any shampoo with zinc can help. You can try zinc supplements as well. Shampoos with anti fungals like tea tree oil can help as well as sujphur based treatments. Best bet quickest and easiest is like head and shoulders. It will tend to get worse in the winter due to less exposure to sunlight as uv light kills the yeast to some extent.
