Found an error when re-reading from the beginning. It seems when selecting "dark hair" in the prologue there's an error that duplicates the word "hair."

I'd guess that the hair color variable is set to "dark hair" rather than just "dark" so when you write smth like "$hairColor hair" (or whatever your variable name is) it ends up splicing "dark hair" in for the variable, thus resulting in duplicate hair.
