I’ve suffered from SD for decades, mostly on my scalp. I can usually control it with prescription shampoos but lately it’s been out of control.

Two dumb questions (I’m new to Reddit and couldn’t find these topics addressed):

1 - I’m a male with short hair but I always just let it air dry. Is that hurting my cause? The scales are way worse on top where it stays damp longer.

2 - I split time between a very dry and very damp place. Does it make sense that it seems was worse in the damp place?

And maybe a really dumb one, would it be helpful if I cut more hair super short and let my scalp get some more exposure to the sun?

TIA for any thoughts!
