The Kyoko hair is a transmapped hair, as are all of Kozaburo's hair objects. Check your material settings. If you want to be able to see the transmapped hair without having to mess with material settings, simply select the hair, the go to the document style menu, there are submenus there for element and figure styles as well. Choose element style, and click cartoon with lines. You will be able to see the hair as a flat shaded object, but it will render normally.
