You can try a good clarifying shampoo and just condition her ends, I have a boy that gets that greasy look the same day of his bath i tried the new shampoo and the clean look lasts about 3-4 days. it is normal for the hair to seem shorter and it probably grows just as fast as the front but the back end generally has a bit more wear and tear on it so the hair breaks off more back there than in the front. I have to keep mine wrapped to get any length in the back. don't worry about the oily look unless you are taking her out it is actually a good quality to have it naturally protects the hair.
