[/INST] Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. As per your case history you are having alopecia aerata. My treatment advice is - 1. Take good nutritious diet full of green leafy vegetables and milk. 2. Apply a Tacrolimus 0.03 % ointment twice daily on affected skin. 3. Take an iron supplement and vitamin B12 supplement once daily for 3 months. If problem persists then consult a dermatologist. Hope I have answered your query. Let me know if I can assist you further. </s>
