If it's mild, with just one or two patches peeling, often over a shower or a cooking area, then the problem is probably caused by moisture from below. Scrape the area right back to the plaster as far around the damaged area as you can, until it becomes almost impossible to get any more off. Paint the exposed area of ceiling with a couple of coats of some kind of sealant...there are commercially available ones, I just use PVA adhesive. Use a plasterboard topcoat finish to plaster over the area, let it dry and sand smooth. You will almost certainly need more than one coat of the plasterboard top-coat to get a good finish; make a good job of the sanding. When fully dry, apply another two coats of your commercially available sealant, or in my case PVA, then paint the whole ceiling. (Obviously, if it's a dirty ceiling, clean the whole thing first). I have been doing this successfully for years. The same procedure can be applied to ceilings where the dampness has come from a leak above, but cure the leak first, of course. If it's a bad one, all over a ceiling, or it's a poor quality ceiling to start with, you might like to think about replacing the ceiling. Now, that is not necessarily as big a job as you think! In some cases, it may be that the plasterboard has not been properly sealed before it was painted, but make sure there are no leaks before you do any work, or you will be wasting your time and money. If it's feasible, I often just "overplate" the ceiling with a new layer of plasterboard right on top of the old one. There are some important points here though...common sense really....you must ensure that the supports are capable of taking the extra weight of the new plasterboard as well as the old, it's not exactly lightweight stuff. If you have good solid joists up there, no problem, if it's metal or feeble timber, perhaps don't do it...err on the side of safety. Make sure you screw up the new boards with longer than normal screws...to go through the old board as well as the new board and well into the timber too. Use plenty of screws since there is no point in using dot and dab adhesive...it won't stick any better than the paint did...still use some on the joints if you wish...tape and finish the joints, replace the cornicing if any (having previously ripped the old stuff down), seal and paint, and Bob is your Uncle. If you judge or worry that the ceiling supports can't take the weight of another layer of plasterboard, then you'll have to just rip the old ceiling down I'm afraid...and perhaps that's an opportunity to beef up the supports too. Good Luck.
