Does electrolysis send the current down the hair (so you must first grow a long enough hair?)?

In brief: Electrolysis needles

Electrolysis uses a tiny, fine needle that is inserted into the hair follicle.
While a hair wouldn't necessarily have to be present, the needle has to enter at the same angle as the follicle is oriented. Having a hair present makes this a lot easier for the electrologist to gauge. There are other techniques for hair removal, like radiofrequency, that may travel down the hair, not using a needle.
