Scalp Psoriasis

How do i know if i have psoriasis on my scalp ?

Symptoms may include fine scaling that looks like dandruff or appear as thick, crusted plaques that cover the entire scalp. Other skin disorders, such as seborrheic dermatitis, may resemble psoriasis. However, scalp psoriasis appears powdery with a silvery sheen, while seborrheic dermatitis looks yellowish and greasy.
