Because of the amount of work involved, it was not uncommon for women to leave their hair untouched for months on end, except to add a little paste from time to time to keep everything cemented in place. Many slept with their necks on special wooden blocks to keep their hairstyles elevated and undisturbed. One consequence of failing to wash was that their hair often swarmed with insects, particularly weevils. One woman reportedly miscarried when she discovered that mice were nesting in her upper decks.
