Hair loss and depression

Rare cases of hair loss have been reported with using Prozac, and hair loss such as this (alopecia) usually shows three months or so after the initial cause, which would fit with your Prozac use. Depression may also occasionally cause hair loss, as may other hormonal imbalances such as thyroid underactivity. If you have not already had some simple blood tests taken by your doctor I think it would be a good idea to do so, and certainly you should see them again to let them know how you are feeling - this could be an early sign your depression is returning.
