Help for flaky dry scalp?

Hey you guys,

I've had this bad candida related dandruff problem going on for years, and now while working on my diet and fixing the problem initially that way I've been using tea tree oil as a topical treatment. While this has worked relatively well I have recently moved from warm humid Australia to much cooler dry Finland, and I've noticed my skin getting dry all over. Any easy relief especially for my poor scalp? I'm not into supps, but maybe something I can apply every now and then when needed?

Thanks!
