Wanted: Thermocap

The Thermocap was an apparatus for the treatment of the scalp to regrow hair. Inventor Aloise A. Merke, a Frenchman living in New York, was awarded a patent for this devise on September 22, 1925 though the patent was assigned to the Thompson Barlow Company. The Thermocap was eventually produced by the Allied Merke Institutes, Inc. of New York. It was nothing more than a cap with a socket at the top in which any standard light bulb could be screwed. The bulb was supposed to relax and open the pores thus stimulating hair growth.

I would be interested in this quack medical hair regrowth apparatus or any other similarly strange examples, like the Evans Vacuum Cap.
