Can psoriasis of the scalp cause permanent hair loss? Traditionally psoriasis has been classified as a non scarring alopecia - with proper treatment allowing hair to grow back.
We now understand that that is not quite accurate. Scarring alopecia lead to atrophy of the oil glands which is a small proportion of patients appears to lead on to scarring alopecia. A handful of publications (dating back to 1972) have shown the development of scarring alopecia in patients with scalp psoriasis.
