This is an adaptation of curly hairstyle (MH alpha 7 version). The licence was GPL, but author was set to unknown. So I consider it CC BY, but the author is the MH team. The adaptation was no rocket science. I changed the texture a bit, so that the hairline looks slightly better. The example picture is from MH and shows the black material on my 'Evi' character.
