Dear Group:  I have been trolling the thyroid files trying to find the answer
  to three questions.   1) Does an overproduction of  T4 
  cause hair loss?   2) Why are fetuses only able to work with T4 and 
  not T3?.  How many subscribers to the thyroid group are doing well 
  with only TR3?   Thank  you,  All.   Edith Wallace
