Having hair trouble.

Megan • Hi I`m Megan and I`m 23.We have been married for a year and now my husband and I look forward to starring our family.
So I have been having trouble with wet dandruff for a while now. I have very long, thick, curly hair. I get those oily spots at the top of my head. I have tried using head and shoulders but that makes it worse. I currently use dove intense repair and that works pretty good. Does anyone have any advice on what I should do or use to help it?
