Hello. . Hello. I answered your earlier question about itchiness. I don't know if you have dandruff. Dandruff can be a symptom of seborrheic dermatitis and causes flakiness of the scalp. However, really dry skin can also cause flaking. Seborrheic dermatitis can affect other areas of your body. Recommend that you consider a dermatology evaluation or based on input in your previous question, consider allergy testing.
