I can totally relate! I have been losing hair for about 4-5 years now and was finally diagnosed with HypO almost 2 years ago and when I told my Dr. that I still had hair falling out after a year of being on Synthroid he tried telling me that I was depressed and wanted to put me on anti-depressents. I was like NO WAY!!! I finally ended up going to a Endo and she checked my iron levels and sure enough they were extremely low and she told me that its the cause of my hair loss. I have now been on 2 iron pills a day for the last 4 months and I have noticed my eyelashes are growing back and I think I may be getting some new growth on my head but its so hard to tell. My eyelashes havent looked this good in years, im so glad I got another opinion and didnt go on anti-depressents. The Endo told me its going to take a long time for the hair to grow back, so try to be patient as hard as that is. Your not the only one out here with hair fallng out.
