She may just have chronic dry skin. Have you given her a period of time where you are not adding anything to her skin to see if it "settles?" I've had one or two that had chronic dry skin. Nothing was wrong with them, other than that.
Here is my approach, its a little long. Take from it whatever you can. I don't know that any of it will work, or if you have tried it already...
How long has it been since she was on a medication? Antibiotics mess up the flora of the GI system. An unbalanced GI may not be able to assimilate nutrients properly. I personally have to wonder if giving a hedgehog a lot of "lets try this to see if it helps" medications without knowing that there is a problem does more harm than good sometimes.
How long did you give the supplements? Supplements can take 6-8 weeks before you even start to see results. With as dry of skin as she had it may take longer. I'd add an omega fatty acid to her diet (flaxseed oil, missing link, etc). I'd likely give it to her nightly or every other night for 3 months to see if it is going to help. Even if it doesn't help, it should not hurt her.
I'd also look into adding a probiotic a couple times a week. I use acidolphilus. Probiotics help the digestive system. There is thought that a healthy digestive system can help skin conditions.
I'd cut out all baths and give her one only if she absolutely needs it. If a wet wash cloth or a foot bath will not clean her, then give her a full bath. But make it short and use only water if you can. Even using Aveeno, bath washes and shampoos can strip the natural oils.
If she isn't itching, leave her a lone for now. If she starts itching I would add a couple of drops of vitamin e oil or flaxseed to her back. One drop in 3 places. Give it 2 nights and add 2-3 more drops in different spots if she is still itching.
This has been my approach with hedgehogs that had very dry skin. Most improved over time, but I've had at least one I can recall who just always had a tendency of having dry skin.
