I think there is something to that. My nape frizz is either wiry or crimped. It is mostly a clump of individual hairs that "curl" at right angles or just fly frizzily straight. I think that some is due to nature as that clump has been bothersome since at least the age of 5.
You can see some of it here.
It does behave better the first week to 10 days after coloring. After that, I think that section could be DT'd every day and not get overconditioned.
