For hair style for teh races will be post beta test version and we have a plan to add new ones which doesn't exist in current FFXIV. Also once the content where you can change the hairstyle in game is released we are planning to add even more hair styles at that time. Regarding the amount color we are looking into it right now to see if we can increase them.
Awesome, now we can all be happy now... ( or can we?)
