DANDRUFF

Dandruff, or scurf, is due to a mild chronic inflammation of the skin of the scalp. The inflammation may be present for many years, the only disturbance being a slight itching. The head is 'scurfy,' i. e. the horny cells of the scalp are shed in large numbers and form scales; and there may be a tendency for the hair to come out.
