seborrhoeic dermatitis and rogaine

I've used rogaine for about 4 or 5 months, and have had some success. In the past month, though, my scalp has started to ooze a yellow liquid that can cake up. It's disgusting and seems to be seborrhoeic dermatitis. I've had dandruff all my life, usually the dry kind but also sometimes oily buildup, but this is next level. I quit rogaine for a few days and it clears up, but comes back when I restart. I also tried switching to the foam version but no luck. I've now noticed that the progress I made is going away.. I'm shedding. For the record I've also been on propecia for the same amount of time (and I haven't quit that).

Does anyone have any experience with this and have ideas for how to deal? I may have to just not use rogaine, which is depressing. Also interesting is that this only occurred after moving across the country. No idea if that's related.
