how long do hairs have to be to wax?

[MrsSnape]

I bought some wax for the first time yesterday and the last time I shaved my legs was Tuesday.

At the moment my legs are at that "prickly" stage and the wax I bought said it was designed for really short hair...will it work yet or should I leave it for a few more days?

I'd leave it and then you'd get a better result and won't have to do it so often. Sounds rubbish now but you'll be pleased once it's done. Ever thought of getting an epilator? I've got one and if you can stand the pain for a bit it's much easier than waxing.
