Your Ferritin levels seem extremely low.
In comparison my levels are Ferritin 24ug/L (Ref Range15-165), Iron 27umol/L (Ref Range7-27).
i myself am trying to raise my ferritin levels.
I would advise you get a full blood test. Which includes Iron, Vitamin D, Vitamin B and also a full blood report on your hormorne levels.
I had my hormorne levels and iron levels towards the lower end and extremely low Vitamin D levels. I too have serious long term hairloss. Further investigations into my hormorne levels showed that I have Polycystic Ovarian Syndrome (PCOS). The good part is that I am now getting the help I need.
