I suggest you find a good podiatrist.

I am apparently genetically predisposed to acquire ingrown toenails as my whole family has had problems with them at some point. However, when I got mine cut out the podiatrist also killed the area on my toe where the ingrown toenail was coming from (maybe a bit like laser hair removal... kill the source). Either way, if the doctor knows what he/she is doing you'll never get ingrown toenails again.
