your question needs further elaboration,like ur
history of hair fall
in the family
associated medical conditions
any prescribed medications
general health and your diet etc
what was the level of fall in the iron
so i mean to say that there are lot onf things which need to clarify at this point.
I would suggest to contact your doctor again and discuss all these issues in detail with him/her.
I am afraid that i cant help you out with such a brief history.I hope you can understand what i am saying.
thanks very much and all the best.
