Levoxyl VS Armour

[Jen]

Dear Dr. Redmond,
In your experience which thryroid medicine is the friendliest to the hair? I have been taking Levoxyl 0.05 for a few years now and even though my blood tests are within normal range, I am exhausted much of the time (and cold, and having trouble losing weight). I have a friend feeling wonderful on Armour. Do you think Armour is a more natrual choice and is it hair friendly?
