Hey glammerZ!! I just wanted to say good luck because most of the bratZ hairs are UNDER 20 WOOZ! 
Most people are getting them from lots of VERY POPULAR PEOPLE! Here, if you are having a hard time in the queue, Then Go on the catalog search and search the following:
Bratz Hair 20
You can put Bratz Hair 20 wooz, but i think Bratz Hair 20 is easier :D
Well, Good luck!! I hope everybody gets a Bratz Hair!
