What is your serum ferritin level? Mine is about 25 , and from googling it's not optimal for hair growth. Must go back to my GP to see about taking iron supplements ( or maybe I'll take supplements for 3 months and see if hair responds) and then retest ferritin and see if has made any difference. Curious if your ferritin is also low. This seems to be very common with menopause so am also looking for the answer!
