Grey shadow that is visible even after a clean shave called? [closed]

Solution 1:

The most common name seems to be a 5 o'clock shadow. Stubble is used as well to describe a short beard, although usually in the form of "heavy stubble" where it describes a 10-day beard of a few mms. Permashadow, or perma-shadow, is a slang word that is used in online forums to describe the outline of the beard that is still visible on a clean shaved face.
