I would just do the same as with a color image, that is,
Filters-->Colors-->Color to Alpha. Of course first you would need to
convert the image to rbg. You can put white to alpha and any shade of
gray, or use the color picker to select an exact value. Select by Color
also works with grays
right! gray hairs are earned. why would anyone want to get rid of them.
here is a tutorial that might be helpful:
