In game "Barber Shop" option

[Shougun]

I remember Yoshi or someone of the devs saying in a interview that we will be able to change hairstyle in the game but it wont be ready at launch.

Yes - It was in another thread talking about adding an awesome job and Edward Scissor-hands was the first thing you saw.

They also will be adding more hair styles and making some hairs available to all of that race rather then just one type ("only dust walker").
