Hello, Welcome to healthcare magic. Hair fall for 1-2 years is called as chronic telogen effluvium. The common causes include anaemia and thyroid abnormalities. Please get your hemoglobin, serum ferritin levels and thyroid status evaluated. You need to continue treatment for your thyroid issue. If the above tests are normal, you can take a tablet with biotin, cysteine and methionine for 3 months. This will strengthen your hair roots. For dandruff, wash your hair with an anti dandruff shampoo containing ketoconazole 2% and ZPTO 1% thrice a week. It is better to avoid oil. If you want to apply oil for conditioning effect apply it half an hour before bath and wash it off with a mild shampoo during bath. Eat a balanced diet with proteins , fruits and green leafy vegetables. Try to cut down mental stress. Hope this helps you. Take care.
