They are NOT default replacements, nor do you need the original version for them to work. The styles that have a recolorable accessory can be found in the hat section of the catalog. They appear in the everyday, formalwear, sleepwear, swimwear, athletic, career, outerwear, and naked categories and are set to valid for maternity and valid for random. These hairstyles are for teen, young adult, adult, and elder females.
So I went through and stripped off all the ugly junk that EA puts on so many of their hairstyles, redid the textures, and made a few other various improvements (such as resizing them, correcting bad mapping, fixing bone assignments, and the like). There are a lot of beautiful custom hairs out there, but for all the cashiers and bartenders and other random sims who seem to build up in my saves I didn't want to use those super high poly CC meshes on them. The first of two parts, I started this project because I wanted more hairstyles for my townie sims.
