I agree that it would probably not work. Glad that YOU posted to this thread about this!
I wanted to find out more, but have been afraid to ask.
I haven't done too much searching about how much a hair is an insulator because I have no doubt that it's a great insulator.
However, what has been bugging me is that if enough electricity were passed through the hair, it might conduct at least SOME.
How much and how long an electric current would be needed to kill the follicle itself without either instantly burning the hair or causing severe burns to the skin, or simply do nothing at all, is beyond me though.. I would think it would have to do more with the heating of the hair itself than the actual passing of electricity to the follicle.. Unless maybe the hair is actually used as a natural resistor??
ehh - just a brain fart - I really don't know.
