Ugh! I get this bad but not sure if it's dry scalp or SD ... My entire hairline from front to back gets it the worst, with severe patches of flaking, scabbing, and intense itching. It tends to go away when I'm in costal temperate climates with soft water which is what leads me to believe it's from dryness. I've been perscribed cortisol creams and such but so far nothing has really made a difference
