I’m significantly more fond of the wonderful Sims 4 mod hairstyles than the EA default ones. I went through the default EA female hairstyles and created default replacements disabling the AllowForRandom flag. Townies now only spawn with the hairstyles in my mods folder. This does not apply to the NPCs already present in the game, such as the Caliente or Pancakes families.
The zip file contains an individual package files for each of the 42 base game hairstyles so you can pick and choose which hairstyles you disable.
