Can you link to a picture?
Did you check XM Sims? That's the site that has the best "curly" hair, as far as I know. Also check Peggy, but it would have to be in the pay section since I know there isn't one that sounds like it in the free section.
Sussi has a curly updo that could fall under the description you gave.

Last possibility (hey, it's almost IMPOSSIBLE to guess what kind of hair you are seeing) is that it's Shannara's updo with the two fat ringlets hanging down on the sides and the rest in a bun. In that case, get it on MTS2.

) then there's one of those at MTS2 too.
Okay, so, while on the topic of "where can I find this hair?" -- does anyone know if the hair on the model at
http://www.noukiesims2.net/Genetics.html (the short curly hair) is a real mesh, and where it's from? It looks sort of painted on, but I hope it isn't.
