itchy scalp fibrosis?

The common complaint of scalp itching is something that intrigues me.

I know dandruff, dermatitis etc. can cause itching

was wondering, does anyone have any knowledge of
skin fibrosis and if a symptom of it is itching - particularly
on the scalp.

SAN FRANCISCO, Oct. 9, 2013 /PRNewswire-USNewswire/ -- The Scleroderma Research Foundation today said that researchers at The Johns Hopkins University working in a novel mouse model of Stiff Skin Syndrome have made key discoveries that may have broad implications for future scleroderma therapy. In a report to be published online on October 10th in Nature, scientists show that integrin-modulating agents can arrest fibrosis in a model of scleroderma-like skin fibrosis and, more strikingly, that established fibrosis can be resolved with such agents. Although years away from an approved drug, the conclusion stands in sharp contrast to traditional thinking about scleroderma's irreversible advance and its resistance to therapeutic intervention. The Scleroderma Research Foundation has supported the work for the past six years.
