>Yes, allergies can be grown out of. Hmmm... that looks like grammar accident waiting to happen. Anyway, when I was a kid I was definitely allergic to animal fur. I use to break out in a rash around the edges of my lips - just the sides, not the top or bottom, and it could take up half my face. I don't know when, but I grew out of it.
I was allergic to yolk, mustard and gunpowder smoke. Nothing big, I'd get a bit of a rash in a couple of places, or my palms would itch and redden. It would go away in a day. The gunpowder was funny to find out - we had those little toy guns with a paper tape and a bit of gunpowder between the layers of paper, and the hammer would hit it and ignite it, with a nice bang and a bit of smoke. Seems to be I got a particle in the corner of my eye, and that's how we found out.
By puberty, it was all gone and replaced with a few mental allergies ;).
