Unfortunately my friend has decided to keep his beard for now, after shaving his head his scalp is feeling the chill, so he's decided to keep his beard to keep his face warm, until his hair grows back to a length he can keep his head warm with, at which point the beard is gone.
Many thanks for all the tips though. Perhaps a mod could put these in the wiki? (the page in there for shaving someone else is completely empty at the moment)
