Open Question: Can low folic acid cause hair loss?

Sunday, I began to have hair loss. It and a lot of it! Every day, hundreds of (presumably 300 hair down!) I have very thick hair, I began to tell a big difference. I see a doctor, because today I think this might be my thyroid. After blood work, which showed that my thyroid normal, but my folic acid is very low. Although I know this is true, low folic acid can lead to hair loss, that it will quickly? Has anyone experienced it? I was 25, this is the most incredible and most complex thing.
