Isaiah 50:6 I offered My back to those who struck Me,
and My cheeks to those who tore out My beard.
I did not hide My face from scorn and spittle.
Was this literally fulfilled in Jesus?
Yes, Isaiah 50 has often been taken as a Messianic prophecy (I'm offering a New Testament interpretation of an Old Testament text).
Although we do not have direct New Testament discussion of anyone plucking out the hairs of His beard, the other parallels to Jesus are quite clear:
Jesus bore the cruel physical and emotional abuse prophesied by Isaiah.
