There are many possible reasons for itching including fleas, allergies, skin infections and mange. I recommend using a good quality, fast acting flea prevention such as bravecto or simparica as well as an omega fatty acid supplement which is naturally antiinflammatory and moistruising. A full physical exam and further diagnostics would then be required if not improving in 5-7days

    Hi there. The most common cause of itching and hair loss on the lower back/base of tail area is flea allergies - so if Oreo isn't already on a good-quality flea medication like Nexgard or Bravecto, this is the first thing I would suggest. If you're positive she doesn't have fleas, then other possible causes would include environmental allergies, food allergies, a bacterial or fungal skin infection, or skin mites (mange). Treatment will depend on what the underlying problem is, so I would recommend taking her to the vet for an exam. He/she can do some simple skin tests if needed to help diagnose the problem and get her started on appropriate medication to treat it.
