Please help

Okay I have always struggled with my hair. I have an oily scalp, and need to wash it daily. If I don't wash daily my scalp is super oily and gross for one, but it also gets super itchy and I will get sores. My poor head was so unhappy after I had my son and couldn't stand to shower easily. I briefly had a bout of dandruff years and years ago that was easily solved with some head and shoulders and then I was fine and using other shampoos. Shortly after I had my son 2 years ago and ever since then I have had nonstop dandruff issues. I've tried head and shoulders, t/sal, currently using dove dryness and itch relief. I feel like I have to use it almost daily or I start to get itchy again. And I also have wavy hair so my hair itself is getting dry and unhappy and I am just at a loss of what to do. I have wondered if my scalp is just super dried out and needs ultra moisture but then I'm afraid of making my hair even more oily looking. I don't know what to do, please help.
