I would say from back to front. wet the hear from back (center) with salty water, use low voltage if longer time such as 8h. I think it depends of the zapper circuit how much the voltage goes down when attached to skin. Exact voltages can not be told told cause the zappers are all little differend. From side to side the head the current causes pain. That is not good since it is talk about the brain. User must feel him/her self. Do not sleep with too high voltage. The salty hair acts like a time relay. When the hair dries the current becomes weaker. A small cheap circuit with 406-435khz (mo ...
