For people who have psoriasis/eczema/bad skin, how did you get rid of your dandruff?

I've been dealing with dandruff since I was a kid, it's always made me really insecure and always wear a hat. I've tried plenty of different hair products, none seem to work. It's not just my hair on my scalp, it's my beard as well. I'm a 19 year old male (Caucasian), I've been already deciding if I want to go bald or not. I still get dandruff even with a buzzcut and stubble. My skin just sucks. Please feel free to recommend products. I'm trying to improve my life and I find this to be one of the most annoying things.
