Victor is a lot taller than the player character, so an 'all hairs' version is not really doable. You need to install a minimum of 2 files, which are the 'Play as Victor' file and 'Victor Hair,' unless you want him to be bald. You can also install invisible helmets so the helmets don't mess with his hair.
You can also have Victor's clothes and hair without replacing the main character, although it only replaces the starting outfit.
