I have been experiencing hairfall for almost three years now. The hairfall pattern is varying and increases decreases in different parts of scalp. Only onion juice works but hairfall increases if i don't apply it for a week. I got a few tests done and readings along with the given normal range are- Ferritin 13.40 (Range 10-400)ng/ml Haemoglobin 11.2 (Range 11-14) gm/dl MCH 26.9 (Range 27-32)pg MCHC 29.2 (Range 30-37) Is there iron deficiency in the body leading to hairfall?
