When would I see results with an FUE? Not just growth, but actual noticeable results.

It can take 6 to 12 months after surgery to see results.  If you are concerned it is best to contact your doctor.

Generally 3 months after the procedure you should see some grafts growing in. After 6 months the growth should be greater and it takes a full year to see full results. 

You can plan on seeing the beginnings of new growth at around 3-5 months.  As time passes and more grafts enter the growth cycle, the hair will become thicker and more robust.  Full results can be expected by approximately 1 year.
