Barber shop is a good idea but as someone above suggested, Activision will NEVER bring it into the game. They won’t even consider or think about it at all, never forget that these are the most money thirsty and greedy men in the entire world. All they care about is money, nothing else. Neither making good games, nor your convenience or feelings have any significance for them.
A barber shop who is actually a barber but not a gynecologist or a surgeon (like in retail) would actually be a good addition to the game. I made a thread about this more than a year ago, couldn’t stand my hair color on my hunter. Obviously, Activision didn’t care, they dont even read EU forums except for deleting anti-boost posts lol. So I rerolled a new hunter in that time 
Also: a small change like barber shop is nothing compared to the 58 boost they bring into the game anymore kekw. Stop worrying about this. It’s like being afraid of table knives in the middle of a nuclear war. Barber shop isn’t even 1% of a retail feature compared to paid boosts.
Here it was:
