Should you layer your hair- It is very fine and quite thin- you often wear it in a ponytail- Would layers make fine hair look thin and stringy?

Yes, layers would make your hair look very thin and possibly stringy.

The answer above is right. I have very fine hair. You can have layers but how about asking your hairdresser to cut your hair shoulder length or a long bob then your layers would look better, and you'd can still wear a ponytail.
