How do you get the hairstyles without a zcard on zwinky

In Zwinky, there are certain items for sale that can only be purchased with a zcard, and as far as I know, there is no cheat to get around it. (Basically it's Zwinkys way of getting you to spend money!). However, you can "buy" non-zcard items in any shop in the mall in Zwinky world. In order to get play money you have to play games. You can even collect play money just by wandering around the town. Each time you go from one place to another, I think you get an extra dollar or something.
