Albeit it might be too soon to ask for more hairstyles we don't even know if they are actually prepared, it's true that more options, even the chance to be able to change yours through a barber or something like that, were said to be able from the release of the game in 2010.

It's high time to see at least a few more options even if no one would modify their chars, because now more people will come and we will be able to have more alts for free.

In fact, there were hairstyles prepared that didn't make the final cut (or I think so), as I've seen images of some of them based on the missing Final Fantasy XI hairstyles like the "onion-hair" male lalafel or long hair female lalafel.
