The rash consists of red scaly patches, which tend to clear eventually, leaving some thinning, scarring or color change in the skin. The scaling can sometimes be quite thick and warty. Some patients have patches on their fingers and toes. When the scalp is involved, hair in the affected area may be permanently lost.
