It's unclear if the
levoxyl (or similar meds like
synthroid) cause hair loss in select patients. Certainly hair loss is part of hypothyroidism and there may be some adjustment period when starting the thyroid med where the hair follicle is effected. Remember, hair loss lags about 2-3 months behind the event that provokes it.
In most cases of thyroid related hair loss, it grows back -- how long is variable - - 2-6 months on average.
I have seen a few patients benefit from thyroid meds in situations like yours, others not. Have also tried selenium 200mcg/day with some sucess in lowering antibodies and improving hair problems.
