Going to the endocrinologist

Medications for hair loss
1

I am here soliciting some suggestions on the right way of going about a visit to the endocrinologist to test hormones, serums, etc?

Im trying to find out what if anything is out of balance that is contributing to my loss.

Which tests are the most important in regard to that?

I have insurance so dont want to make it totally obvious that mpb is the main concern.

Thanks a lot
