So the hair styles and colorings you can start with are pretty basic. That's fine to begin with - but it would be nice to see some more exotic colorings and styles in the Cash Shop at least.
Greens, blues, pink, etc for hair (in different shades, they can be made to look nice they don't need to all be neon or anything). We have Wings and Football uniforms and stuff in the Cash Shop already so it's not as if everything needs to look 100% serious - so exotic colorings of hair would fit in nicely.
The styles for girls aren't all that varied (I haven't tried guys to see, but I'm guessing they are about the same). It would be awesome if some extra styles were opened up in the Cash Shop for sale.
The color would be the easiest and quickest to implement and would be a pretty good seller I believe in the Cash Shop.
Are new hair colors already planned to be added in the Cash Shop for later?
