Vector Electrolysis - As it turns out, it is completely unnecessary to insert a needle to produce sodium hydroxide in the hair follicle. The Vector machine works by simply grasping the hair with tweezers and applying a highly conductive gel with silver chloride. Without the electrically conductive gel this process would not work, as hair cannot conduct electricity. Applying silver chloride gel to the hair above the skin allows electrical current to pass over the non-conductive portion down into the hair follicle. Professionals can use the Vector System with a traditional electrolysis needle in place of the galvanic tweezers.
