Morgan:

Interesting question about the conductivity of hair.

Actually, the hair is a complex containing certain protein structures.  The
protein is RF conductive.  Although engineering is playing a more
significant role in biology, there is still not a well defined field of
biomechanics or bioelectronics.  It is surprising, though, how much
technical work is being accomplihed by a relatively small community.  Such
questions as "what are the inertial forces of the enzymes entering the
blood stream" would have been meaningless a few years ago.  But now we have
the tools to answer these questions and examine new aspects of virul
intrusion.

 RF is being used in medical treatments more than ever.  But RF is still
very dangerous and so we need to help people proceed carefully with any
knowledge we have.  The questions about hair are increasingly important for
reasons beyond cosmetics and business enterprise.  The "Help our
girlfriends" discussion is very relevant from the biological as well as the
marketing side.

Also, I liked your question whether or not hair is an isolator.  In terms
of the clasical BAND GAP theory I suppose you could say that it is not
because it is not a crystaline structure.  But when we are dealing with
organic substances, AC and pulse circumstances as well as variable
impedances, we find new will factors apply.

Thank you for your question.


Richard
