have you been referred to an endocrinologist in amongst all the specialists? they are the docs that focus on hormones and may be able to tell you if there is an imbalance there. i have alopecia (a term used to describe the hair loss, not a cause) due to hormonal irregularity. there is something i can take to correct it but not until i am sure i don't want any more children as it inhibits a certain hormone group and would be harmful to a developing fetus
