I've been seeing waxing ads for a while now and was curious. Mostly about how long regrowth took. Today I went into Boots and got some strips, got home, tried it. They're type where you rubs them to warm them, smooth them on your legs (or wherever) and pull. Thing is, they didn't really seem to work. They only got about 30% of the hairs after about 4 tries. Not sure if I'm doing anything wrong or if there's a certain way to do it. Maybe it was because my legs weren't full on hairy yet, only about 3 days of growth. Any ideas?

EDIT: I apologise for my poor way of phrasing. I've been ill for a few days and I can't work out if I'm reading it wrong or if I typed it wrong or both. I'm not going to try to correct it but hopefully the next thing I type makes a little more sense.
