The hair back there is often the last to dread because it's softer and finer.

I did four rounds of twist & rip on my nape and none of them took. The only way I could get them to stay together long enough to start dreading was to backcomb those sections and then very lightly crochet the tangles together... just a few passes with the hook. I know crocheting isn't recommended or thought of very highly around here, but that's what worked for me.
