First, be sure you have an alpha channel. Other than that, it depends on the backgrounds.
If they are complex, the scissors select tool, while cumbersome, can be helpful.

I find the 'Foreground Select Tool' can be useful in cases where there is a complex background.

a. roughly mark out the face b. let it do it work
c. press enter
d. apply the quickmask
e. clean up the selection
