The Scientific American reported a fix for hair loss in August 1914. Let me share it with you. “A gold wire 1/500 inch in diameter is bent to form a loop barely visible to the naked eye, which is then threaded with a woman hair of the desired color and from 8 to 12 inches long. The wire is introduced into a Pravaz hypodermic needle and then bent and cut, forming a tiny hook. The needle is inserted normally, twisted and carefully withdrawn. The doubled hair is anchored by the hook in the subcutaneous tissue. As many as 50,000 hairs may be required. ”

That amounts to 15 grains of gold. Someone made money out of this.
