From time to time, methods of hair removal have been advertised where the hair is grasped by a tweezer  connected to an electric current source.  The electric current allegedly travels down the hair shaft to destroy the hair root without any probe or needles.  I am not aware of any reputable scientific evidence published in peer-reviewed medical journals to support the effectiveness of electronic-tweezer/no-needle methods of hair removal.  It is my impression that the no-needle and electronic tweezing methods are no more effective in permanent removal of hair than ordinary tweezing.
