This, just this.
More hairstyles will be added in the future guys, have a little patience.

The dev team has been whiped bloody and has been kept going on pure cafeine IV drips by Yoshi to get us the 3 GB patch with at least hours of extra content.
I wouldn't be surprised if more of those were to be added in in-between patches.
