This week’s Novel Cure of the Week is described in a study published in 1979:
“Nursing care study. Hair Pulling: Cured by a Motor Cycle Helmet,” A. May, Nursing Mirror, 1979 Jun 7;148(23):37-8.
We do not have access to that journal, and would likely enjoy seeing a copy of the article. [UPDATE April 3: Kurt Verkest sent us a copy, for which we thank him.]
The photo below shows a motorcycle helmet from that era; it may not be the same model that was used in the study.
