Jep… unfortunately the “required items” have been mixed up for quite a while or listed very puzzling. mostly they seem to list all the items that they work with (because it needs at least least one of the items to be used, with hair that’s not even true, you could use hair without a figure to wear it too *g*). In case of this hair the ‘product requirements’ seem to list the morphs of some of the figures the hair can be used with, that doesn’t change that you won’t really need them for the hair to work, though.
The important thing here will be, that the hair will work with your programm of choice (in this case dazstudio and poser) and with the figures you want to work with. this hair will work with Victoria 4, Aiko 4, Victoria 3, Michael 3, Aiko 3, Hiro 3, Millennium Baby 3… so if you want to use it on Aiko 4 you will be fine
Moreover, this is a hair from AprilYSH ... there’s a site from AprilYSH somewhere on the web, where s/he offers a lot of fits for hair to other figures than the one that are built in.
Edit to add a link to AprilYSH’s freebie site with hairfits and other cool stuff
