In the settings find the hat, in this case Flak helmet, and change the default setting to "Hide hat" and then make sure the drafted setting is using "hide all hair" or "hide hair, show beard" instead of using default.

I am having issues with this mod. I added it and it is not working. When my pawns laydown they go bald till they wake up. Their hair is not visible with helmets. I have a pawn with a simple helm and have it set in the setting to hide all helms. The helms are still visible and their hair isnt. I am not sure what is going on.
