Hummm... Did you take a look at the link I posted that shows off Whitley Gilbert's hair. If you didn't, here it is http://www.nappturality.com/forum/sh...&postcount=475
It freshly washed and product free...just like my hair is in the example I posted.

But there is a visually distinctive difference between the way her hair clumps into coils and hangs and the way mine just draws up into a puffy looking massive cloud.

That's pretty much the distinction that we make between cNapps and non cNapps. In that pic of Whitley, she is easily some version of a 4A.

Now I've seen some cNapps who have hair that naturally clumps (see middle pic for example http://nappyme.wordpress.com/cnapy-albums/ ) but there aren't really any spirals or coils or curls it just draws up and sticks straight up. Perhaps the young lady in this pic does have hair that has that infamous z pattern...dunno.

But again...the point is that cNapp hair does not CLUMP to show off any type of curl/coil/wave pattern. As I look at the young lady's cNapp hair in the above link... I can't tell what's going on with her individual strands. But when I look at Whitely's hair, she quite clearly and most definitely has coils. So that's the difference, in my mind, between 4a and 4b/cnapp hair.
