electrolysis

It consists of a trained person who will very carefully stick small needles down into each hair follicle, and apply electricity to kill the root of the hair.

It is expensive, slow, and uncomfortable, but there aren't any other choices out there.

Electrolysis occurs in electrolytic cells, which consist of two electrodes in a molten salt or solution. The cell is driven by a battery or some other source of direct electical current. The battery acts as an electron pump, pushing electrons into one electrode and pulling them from the other.

This allows chemists to reverse the process found in galvanic or voltaic cells to produce desirable chemicals, electroplate metals and recharge a battery.
