I was diagnosed with androgenic alopecia. a year ago my hair stopped falling out. no within the last week it has started falling out again. why?

Stress: Stress is a major cause of hair loss, think major illness, hospitalization or surgery. So is thyroid dysfunction, both under & over-active. Androgenic refers to male-pattern baldness which is typically associated w/too much Dht (dihydrotestosterone), a breakdown product of testosterone. We use Finasteride to stop this conversion. But it's also considered category x in women. Talk to your familydoc.
