1. Exposition

What does the whiteness of the son of man's head communicate?

Revelation 1:14 (ESV)

14 The hairs of his head were white, like white wool, like snow. His eyes were like a flame of fire,

The one who looked like a son of man had white hair on his head, very white, pure white, like snow (cf. Daniel 7:9). The whiteness speaks of age and thus of wisdom (Job 12:12). The word like is used to communicate that the white is beyond the whiteness of wool or of snow.
