What is the remedy for Eczema in scalp and chest? Homeopathy/Ayurveda?

I notice red patches in the middle of chest in 2002 and in 2005 the severe dandruff problem (since 2001) found to be none other than Eczema. Scales from red patches on few areas of scalp. Few on chest and few on back.

Applied Conaderm shampoo, Meta Foam on scalp and Mometasone Furoate Cream for skin on chest. When I apply it soon disappears and reappear again after some time and aggrevate when take eggs, fish and groundnuts.

Please provide me permanent cure for eczema.
