If my SO expressed an an opinion that my beard looked stupid and should be shaved off I’d be even more inclined to keep it, because I’m THAT sort of contrary pain in the arse.
However, the last time I did grow one I myself was the first to admit that my facial hair:
a) Looks nothing like the hair on my head – different colour & texture.
b) Makes me look 30 years older than I am.
So, say nowt, let him work it out for himself.
Might be worth asking his mates to gently take the piss or point out that he looks he’s got a dead honey badger glued to his chin.

Rusty ‘Pube Face’ Spanner.
