I cannot completely guarantee that some minor irritation wouldn't ensue, but I'd say she would be all right - especially if the shampoo didn't touch her mucous membranes (mouth, eyes, nose, etc.) If it did, it would more easily cause an irritation, but in that case you would probably notice it right away due to adverse cat's reaction like sneezing or reddened, watering eyes. But I wouldn't expect it to be serious either.
In general, human shampoo shouldn't be used for cats (and vice versa) because optimal pH for cat skin is different that the one for human skin, thus prolonged use would be problematic. But a single, incidental use like in your case - I don't think so.
I'm oversimplifying this of course - human shampoos are different enough among themselves, with the baby shampoos regarded as being the most gentle. But even if it wasn't a baby shampoo - at worst, I'd expect a minor and transient irritation to ensue and then quickly become a ghost of time without any intervention and she will be fine.
