Plucking hairs with tweezers...

Does plucking hairs with tweezers help or hurt future electrolysis?

Hurts. It makes the hairs coarser except for on your eyebrows as far as I know. I ended up with a bunch of coarse hairs on my upper lip and chin because I went overboard tweezing every hair I could see with a 12x magnifying mirror.

Removing hair with the root is counteractive, whether it’s by tweezing or waxing, because it makes the hair stronger over time and thus more difficult to kill later.
