Is balding accelerated by external factors like stress, or is it just genetic?

Androgenic alopecia (male pattern hair loss) is genetic. There are other forms of hair loss, such as telogen effluvium, that are caused by stress, poor diet, etc.

There is also auto immune related hair loss like Alopecia totalis where someone loses all their hair, including the sides (which doesn't happen with most hair loss patterns).
