This is one less gold sink needed, I see no improvement in gold granted.
Gaia has an economist working for them.
Gold grants when people join, when a site gains more users, more gold is pumped into the system, simply by the general activity of all the new users. Gold sinks are necessary to combat it. It's a fine balance that Gaia works hard to keep.
The hair in the salon are dirt cheap.
The items with wigs in them are expensive. Quest them. It's much better for Gaia to have things people want than to just give them to us for free. It's like facebook games. If you pay cash, you get better items. Makes it tempting for Gaia, makes Gaia money. That's why there is rare stuff.
