Has your vet checked out what might be causing the itchiness? I would start there. We had some itchy, dry skin going on so added coconut oil, mixture of Fromm surf & turf and Fromm duck. No more itchies. I think getting away from grains helped. The coconut oil has really helped the coat also.
There are lots of know,edgable folks on this site to help you out.
