I think it's TV so I doubt that the writers would tell Evangeline, you can't shave. Oh and by the way you going to be making out with Josh(Sawyer) in the next episode with stubby legs. As for the guys stubble. I have no idea pretty much all the guys have had perfectly even facial hair for what 72...75 days now. I think it would be funny if by the end they all looked like Santa. Ha! However they did have a hatch for all of the 2nd season so they probably shaved in there. They even show Locke shaving. Now though the hatch is gone. Oh no!
