barbershopGo to a barber and join a queue for a battleground using the new “Join from anywhere” battleground feature in the pvp tab.

Sit in the barber chair and choose a style and color etc, when you are done wait for the battleground to come up and enter the battle.

The hairstyle you selected in the Barbershop will stay when you spress the Enter Battle button.  The new style disapears when you logout. But you can simply get a new trendy style the next time you play!
