Actually a lot of people think that they might actually be serious about Tristan's hairstyle
Because most people assume that he will get a larger story with that redheaded chick you can see in some of wedding pictures. And that is his "hot" new look for his new love interest
Poor girl
(and I normally like Tristan)
I think the hair might stay but I assume the beard will go before his new story starts. => that kind of messy moustache/goatee thing always seems to be a signal of deeeeeep, deeeeep emotional anguish on Tristan.
(which I say... ok, it made sense for example when he was put under house arrest after confessing his love for Helena => aka he was in deep anguish ERGO he stopped shaving right, but why on earth would you actually want to intentionally look like that for your wedding, you know, when you still assume that it will be a happy occasion?).
Anyway, because of the new chick it's kinda unsure how long Tristan's raaaaaaaaaaaaaaaaaaaage phase will last and how bad it will get or whether nuChick will snap him out of it. But it could also be that it might take a while till she does if she's still busy in her introduction story for a while.
