Because the people who design the loot aren't the ones that design the levels.

I'm guessing either:

- the artists designed the full set, but a designer declared that important NPC's shouldn't have helmets

- it was supposed to be used, but they changed their minds on placement but the message to move it was lost in communication

- they, collectively, forgot

Either way, if you're on PC, I'm sure someone has made a mod for it by now. Hope you don't consider that cheating
