Until recently my daily driver was a 96 XJ6. A sagging headliner was quite a common problem with these cars as the foam on the back of the lining dried up and degraded over time, mostly caused by heat beating down on the roof.
It was much more common in warmer climates but still happened here in Ireland and it happened to mine. On the Jag, the best solution is to remove the headlining board complete. A lot of bits and pieces need to be removed first and the passenger seat needs to be lowered fully to get the lining board out the rear drivers side door. Some folding/bending is needed, likewise when reinstalling, but it is doable.
Depending on the type of car it may be easier. The best thing is to then remove the fabric completely as just repairing the bad spots will be a short term fix as the rest will follow suit eventually. After stripping the fabric off it's best to replace it with new. F.J.Keogh motor factors in Glasnevin do this fabric is various colours. Clean the surface of the lining board completely to remove any old dried out foam particles. A nail brush and light sandpaper will do the job.
Use the old lining as a pattern to cut your new lining. Cut the new lining a tad bigger so you can mark parts of the outer edges for reference points if needed.
It's no harm to give the lining board a light spray of adhesive to prime it and prevent the next layer of adhesive from soaking in too quickly.
Lay new fabric down on the lining board and fold it back in half. Spray the exposed part of the board and the fabric to be stuck to it. Any good quality heavy duty spray adhesive will do, similar to that used by upholsterers or carpet fitters.
Fold the fabric down onto the board, starting along the centre line, working side to side towards the "front" edge. Don't stretch the fabric too much. Better to allow it to tighten as it dries out and leave enough play or slack to work it into any recesses etc. Then fold the other end back and repeat. Leave it to sit for a few hours to stick and dry, before wrestling with it, or hanging it "upside down" as it will be when refitted.
Wear latex gloves!! Change them frequently!! Work in a clean environment.
What's the car in question?

Double-sided carpet tape if you're really looking for a quick fix!
That stuff could stick a fish to a wet mirror.

How would you get any adhesive into where you need except via one edge of the headlining?
