When you get tired of combing your hair, abnodate it.
Abnodate
(Ab"no*date) v. t. [L. abnodatus, p. p. of abnodare; ab + nodus knot.] To clear (tress) from knots. [R.] Blount.

We could abnodate that four-in-hand knot we've be writing about today...

Or is this unknotting reserved strictly for tresses as you've noted?
