I suffer from Hair Loss (Hair Fall), is it AGA or Ferritin induced ?

I have been suffering from hair fall from since sometime. I am unable to identify if it’s AGA or Ferritin induced hair loss. My hair loss is equal all over, but a little more in sides in the TOP of my head.Based on my recent blood test report, I have slightly high iron(31), where max

normal is 27 and high % Fe saturation (58) where max normal is 50. But my Ferritin is Low (29). Since my iron is high and Ferrin being Low, how do I increase my Ferritin. I have tested for thyroid and results are normal.
