Everyone in my family have complete hair, so its not a hairditry, I have been taking eltroxin since childhood- half capsule daily morning empty stomach. But if I forget to take for some days lot of hairfall starts. I apply oil everyday. But from the past 6 months-1 year excessive hairfall started, density of hair has reduced a lot, hair has become thin and less, I removed hair for 30 days every week for 1 month still did not help. Recently I did my T3-T4-TSH Test but it shows normal. please suggest medicine to stop hair loss and regrowth of hair and also suggest blood test to identify the cause of hair loss.
