Depends on what's wrong with it. Grass seed is pretty inexpensive, so if you just have some bare patches to fix, then a little seed is all you need. Nearly all species of lawn grass can be planted by seed (though not all varieties).
If your lawn is thin or bare over wide areas, you should probably overseed the entire lawn. More expensive, but again, grass seed goes a long way. All you need to do is mow the grass short, go over it with a verticutter (which you can rent) then overseed. Fertilize, keep watered and in a few weeks, the new grass should be growing. You could do all this for $100 - $200, depending on the size of your lawn.
If you have a spreading grass like St. augustine or bermuda, and the bare patches aren't too large, you can just give it plenty of fertilizer and water, and it will eventually spread back over any areas where it died out.
