I realize that this may have been addressed already but, as we all know, the Reddit search engine is not the greatest and I couldn't find it. Is there any reason why Jack's hair is the same in the sideways timeline as in the "current" timeline? In the original timeline on the island and in the flashbacks, his hair was always short and unparted. Even when they get off the island, it's longer but unparted. Now that Jack is back on the island, his hair is longer and parted, as well as in the sideways timeline. The writers seem to almost always change characters' hair in order (I would assume) to differentiate between story/time lines. But these are not differentiated. Any thoughts? Or a link to a previous thread where this was already discussed?
