Big Afro Hair:

Honestly this one is so simple and was so easy to make that it feels like I'm cheating. But it looks ok enough to me, and when you need an afro, I think this one would work in a pinch. :)
This is carrara strand-based hair attached to an invisible mesh and rigged to conform to Genesis 1. Currently this is usable only in Carrara (and by extension in Octane for those with the Octane for Carrara plugin). In future I intend to explore options to convert these hairstyles to something that is Studio-friendly.
Merry Christmas! :)
