Well, I hope that you would check out the hair in my store with my favorite curly hair being the Lady Gaia http://www.renderosity.com/mod/bcs/?TopID=359593&sub_category=3D%20Figure%20Essentials%3BHair&vendor=RPublishing, but it's short and our others are more wavy.

So here's the link to most of the v4 hair http://www.renderosity.com/mod/bcs/?TopID=359593&sub_category=3D%20Figure%20Essentials%3BHair&figure=Victoria%204  (any not hair not shown would be if vendors didn't put their hair in right department).  There are some really great looking curling hair models in there.

Hope that helps you find exactly what you're looking for.
