Wanted: Evans Vacuum Cap
The Evans Vacuum Cap was produced ca.1905 by the Evans Vacuum Cap Company of St. Louis, Missouri. As the name suggests, by placing the cap on the head and then creating pressure via vacuum, blood flow to the scalp was supposed to be stimulated enough to generate new hair growth. The Hygiene Vacuum Cap was a variant of the apparatus.
I would be interested in this quack medical hair regrowth apparatus or any other similarly strange examples, like the Thermocap.
