Abstract
A device and method to cause hair loss or prevent or inhibit hair growth. The invention uses plasma (ionized gas) that is generated by flowing gas in close proximity to an electrode that has a high potential applied to it. The result is a stream of charged gas particles that are directed to the skin that contains hair. The flowing stream of gas is held above the surface of the skin. Additionally, a grounded conductive material is affixed to the skin to dissipate any charge buildup on the skin and focus the plasma.
