My Inquisitor just grew out his beard when the BE became availible.
I went with Scout Harding's long braided hairstyle for a while, but eventually I had to accepted that the weird glossy-glossy shader they insist on adding for each hairstyle for whatever reason (whose hair actually looks like that?) made it look too undenieably straight; Kel looked more like gearing up for a James Brown look-alike-contest, rather than a veteran ranger with long heavy dreads.
In conclusion, he looks battle-worn enough. In my headcanon, those two particular years didn't really change anything about the thirty he's lived adventuring before already.
