The hairs grow at different times, so even when you wax, there's more hairs about to hit the surface and start poking their ugly little heads through. Those are the ones I pluck, but within a couple of weeks, they're coming through faster than I can be bothered plucking them (plus it's really hard to pluck effectively when you can't see them properly, and plucking with glasses on is a bit of a trick which I can't be bothered learning), so usually at around the month mark I give up and get them waxed again.
