Hello. I have hair loss - and it's getting worse. I had my ferritin levels checked two years ago and I had a level of 17 (normal range was 15 - 155) so no treatment was needed. I had it tested again last week and now have a level of 12. However, my doctor says that normal level is now counted as 11 upwards so I am still fine. I am not fine - I have bald patches! Is it something I can work on myself or do I need to get a different doctor? Thanks!
