I suggested this long ago, and @Rex asked the forum to comment on the suggestion. I can only suppose the overall response was negative. I can't see any particular production problems in providing one series of clips, of the several used for each card, in which the performer started with hair up and after a few clips let it down. Problems, in the form of extra time being needed to re-do the hair, would only occur if this was repeated. The particular series of clips could be either the first or the last shot for a card.
I think that such a feature would fit well with cards that start with formal clothing such as that worn by office bosses, secretaries, librarians etc. who then reveal a less formal aspect of their nature.
