Picture of Psoriasis of the Scalp
The scalp may have fine, dry, scaly skin or have heavily crusted plaque areas. The plaque can flake off or peel off in crusted clumps. Sometimes psoriasis of the scalp is confused with seborrheic dermatitis. A key difference is that in seborrheic dermatitis, the scales are greasy looking, not dry.
