@Mirzaba ok, so with brows i found it helpful to practice brushing them into a shape i liked before i started plucking them. you can buy spoolie brushes, but i just use a cleaned mascara brush.
it hurts a lot the first few times, but if you hold a hot towel/flannel/etc over your eyebrow for a few mins beforehand it doesn't hurt anywhere near so much. the hair root will get used to being pulled out after a few times and it will hurt less and less each time. bear in mind even if you've plucked strays before, it can still hurt if you start plucking hairs you've not plucked before.
