Just followed an interesting line of research about thyroid problems and MS--since thryoid runs in my family. I found a study that says up to 24% of the people on interferon 1-a and 1-b develop hypothyroidism within the first year of treatment. Hypothyroidism can cause hair loss.
This study suggests you get tested if you're using interferon.
