My wonderful black cat has dandruff!!! Any suggestions?

Hi! My cat has dandruff. She typically has allergies and is on a specialized diet. I comb her about 2 times a week, but I am going to boost that up to at least once a day. Lately I have been feeding her some table food here and there - chicken, tuna, sometimes even yogurt. She has had to get shots for allergies before.

Is there any advice to help her get rid of her dandruff?

Any info would be greatly appreciated!!!
