See the
4B pic thread
I guess it's because I've spent so many years online looking at a million different heads... it was kinda obvious to me that hair was not growing out of anyone's scalp that way. I don't think there's a point to typing hair weaves because the hair is MADE in a machine or by hand or treated in some decidedly unnatural manner, usually by people who know nothing about black natural hair, which often gives the appearance of "types" of hair that don't really exist. I guess 4b can look like that if it was some type of set on a twist-out, but hers is way too uniform throughout, and the hang looks unnatural coming from the roots like that. Trying to imitate 4b is often an exercise in failure, IMHO.
As far as kinky weaves, I do think Ediese's (sp?) is rather convincing though.
