Not all related: I can see itchy scalp as a possible allergy but eating fish cannot immediately cause you to have thinning hair and dry skin. This is related to a more chronic cause, did you get your thyroid checked? Did you see a dermatologist? You may have an unrelated skin condition.

May not be allergy: Allergic reactions generally occur immediately. Can get hives, angioedema, wheezing, runny nose, sneezing, nausea, vomitting, or diarrhea. Dry itchy skin is not a sign of an allergic reaction, but could be eczema flaring from ingestion of a triggering food.

Time to see dermatol: It is time to see dermatology and get a definite diagnosis. It may be psoriasis. You can try T-Gel Shampoo which might help.
