Hello and welcome.
Thanks for your query.
Yes, iron deficiency
does lead to hair loss, and correcting it solves the problem in most cases. But, it also depends on the value of your serum ferritin. If it is very low a proper dosage should be prescribed, in order to avoid a delay in bringing it back to normal. Please do not rush this as we would not want it to lead to a toxicity. Be patient, although it takes time, your hair will start growing back soon.
Next, has a full check-up being conducted? One of the most common causes of hair loss in women is relating to a thyroid disorder
. If this hasn't been checked, you could request for your thyroid profile to be checked as well. This is in order to rule out other causes leading to hair loss in you.
I hope I have succeeded in answering your questions, you could write back to us anytime for further clarifications.
