They are mostly light, and flakey, so flakes come off like
dandruff. Even if I spend months not itching them, there are still some there. Sometimes, it's better than others and clears up. But it seems to be a constant problem, because, if I get rid of one patch there's just another somewhere else.
They are not really itchy unless I think about them, even then It's overcomeable. Not like how a rash might itch.
I also have dyed my hair a few times and used bleach.
