Again you are doing great with her and even if there is a minor set back it won't last long. A couple words of caution, however, appear to be in order.
The first is that a kitchen in operation is much too dangerous of a place for any bird to be. There are open containers of liquids, such as pots which may or may not be extremely hot and a quick dip into one of them would be disasterous. There are hot surfaces and sharp implements and some items emit gasses which can kill your bird in seconds. You don't even have to smell these gasses, but it is why they used to use canaries in mines.
The second is being around nail polish and such things. I don't know a lot about what a nail technician does but have seen some pretty fantastic things done with nails and I do know that most nail polishes have a strong chemical odor. Please try to remember that a birds respiratory system is about 20 times more sensitive than ours and that it takes two breathing cycles to exhale what was inhaled on the first cycle. We do it all in one cycle..
Please read and make a hard copy of the list that starts on the second page of this topic.

You are doing well but pay attention to this list, please.
