I'm sorry to hear that Princess is having this problem! There are a number of different things that can cause hair loss in cats, so it's hard to say what might be going on without being able to examine her and do some testing. The most common possibilities would include allergies, fleas, a bacterial or fungal skin infection, or skin mites (mange). Treatment will depend on what the underlying cause is, so I would recommend taking Princess to the vet for an exam when you are able to. He/she can do some simple skin tests to help diagnose the problem and get her started on appropriate medication to treat it.
