Changes in hairstyle are illogical.

'Do No. 1:

The 'Usual' 'do.

Well this is more or less it for four years. The hair line moves back occasionally.

'Do No 2:

The 'Tuvix' 'do.

I wasn't sure if I should put this under Tuvok or Neelix, so I decided to put it under both.

'Do No 3:

The 'Cool Dude' 'Do:

'Future's End' may have given us Chakotay/George, but it also gave us Tuvok in this fetching scarf. Okay...so it's not exactly a hairdo but I thought I should add it. It's not as if he does much else with his hair.
