Sometimes fleas can be difficult to get rid of. You might want to get some Frontline spray from your veterinarian to get rid of the fleas. It is essential to get rid of all the fleas because pets develop allergies to flea saliva and one bite can set the allergy process off. To address the allergy component I would use Derma-IonX orally. Derma-IonX which is an oral homeopathic product stimulates the enzyme systems in the body which reduces itching and inflammation, promotes healing of the skin and helps with assimilation of nutritional components in diet and supplements. The supplements I use along with it include probiotics and Omega 3,6,9. Together with Derma-IonX it produces a synergistic effect for a faster response. I would also suggest that you give your cat only filtered water for drinking and bathing if your water contains chlorine or fluoride. For the dietary modifications you might want to try a grain free diet for a while. This all should help with the dryness of the skin and coat.
If you need to get more shampoo consider Defendex shampoo which is nontoxic and washes away debris and soothes the skin. Using these products is a simple and effective way of helping resolve a difficult condition.
