Well, since SmallFry pointed this out (thank you!) I pondered on the thought that the one exception where it makes some sense to wash one last time with a clarifying shampoo could be people who were straightening daily an using entire lines of 'cone loaded products (shampoo, CO, serum, etc.), especially bits of added serum to keep the straighten an extra day or two. But then I'd recommend doing a DT immediately and then the next day start CG from the first step. I just don't want everybody thinking clarifying is necessary in every case because even brushing/styling causes any film on the hair to break down.
