That Otherton hair salon must be awesome!
From these Season 4 caps of Charlotte, Juliet, and Kate, it looks as if they found a battery-powered spiral curling iron in the barracks that they could trek through the jungle with them. Juliet's hair was unusually poofy on the beach all of a sudden in The Constant, and in promo shots of upcoming episodes all three look like they've been visiting the DHARMA hairdressing station. And when did Kate learn how to twist up a cutesy bamboo hairband? Her hair looks like it's tiara-prom-ready, for heaven's sake. Even Rose has twirled up her hair in Season 4.
OK, so I kvetch, but sudden changes in details and continuity like this stand out with me. Be glad that you weren't sitting next to me in the theater when I saw Total Recall! But seriously, it must be hard on the actors to go to work clean every day and then get grunged-up for action, so I sympathize. Maybe since LOST will be following the popular glam TV shows this season, TPTB decided to pump up the glam on LOST a bit to attract new viewers from those shows. It's understandable. At least Claire and Sun still have their natural island hair, so all realism has not been totally abandoned. But in all fairness, Josh Holloway has been complaining about Sawyer's hair getting too long, so he should be allowed to give himself a haircut with one of Locke's knives, if we are to believe that the girls are setting their hair with some kind of bamboo curlers and seaweed gel. :-)
