Choosing which .iff files to use on CF's

I don't understand something about CF files that have multiple hair changes. P.J. Washington for example has 18 files for 7 different hairstyles. How do you choose between each, or do you put all 18 files in the mod folder? Also, why are headbands so difficult to add this year?

i would think you would put all 18 files so you can have all the options and such

Use all and select the different options when on the player appearance screen. Cycle through the headband options.
