Someone wrote a diy electrolysis guide. I’m too dumb to explain it but maybe you can figure it out

Direct copypaste

You will need: two 9V batteries connected in series, three multimeter probes (two standard probes + alligator clips; one double-sided probe with alligator clips), a multimeter that can measure current in tenths of a milliAmpere (microAmperes are best) and an electrolysis needle suitable for your hair thickness like Ballet needles (for example, F3 or F4 size for a beard, 0.004 inches = size 4, and similarly, selected according to hair thickness; F and K differ only in the thickness of the shank), a heat-shrink tubing to attach it to one of the probes (4-5 mm wide probably, keep in mind that the ballet needle shank and the probe needle must fit inside), some kind of dense tube to cover the needle after work, a stainless steel spoon, tweezers, a magnifying cosmetic mirror, some kind of face light that does not blind the eyes (head flashlight pointed slightly down works okayish, but soft light to light under the chin is much better), sterile alcohol wipes.

Connect the + of the two 9V in series to a double-sided wire with crocodile clips, connect the other end of the wire to the spoon, and place the spoon on the floor.

Connect the - to the COM terminal of the multimeter with a single-ended probe with an alligator clip, and connect the multimeter’s current measurement output (sometimes current and voltage are measured on separate ports, look at the markings, find A or mA or uA) to the probe we will be working with.

The working probe with a ballet needle attached with a heat-shrinkable tubing. Stick it in for a time so that it does not exceed 20 mCoulombs (current in mA * seconds = mCoulombs), otherwise, they say, there might be scarring. i.e. no more than 20 seconds at 1mA, or no more than 65 seconds at 0.3mA, or 40 seconds at 0.5mA.

Insert the needle carefully along the hair growth channel, there shouldn’t be any significant resistance. This is NOT an injection, it is almost painless even, before the current is turned on. Once you have inserted the needle up until a slight resistance at the end, freeze and carefully place your bare foot on the spoon, and wait, watching the multimeter to see how much current is flowing and how much time you approximately have (put a clock with seconds nearby)… I need about 20 seconds at 0.5mA to be able to remove a hair with the tweezers without resistance afterward. I noticed that when the hair is done, it starts to hurt a little less. If you don’t feel it, judge by the timing, and by how easy it is to pull it out - with and without treatment. There should be almost no resistance on the properly treated hair. After you waited the appropriate time, lift the leg off the spoon, pull out the needle, and pull out the hair with tweezers. It’s easier to start with hairs on the chin.

It literally makes me look so old wtf
