Messing around with the settings sadly didn't change anything. I think the problem is really just that Volition didn't make certain hairstyles fit properly on the heads. And because of that, when you get certain angles that allow you to see under the hair, there are no textures inside, and you can simply see through it. But I have no clue why a red background makes the Boy Cut go completely haywire.
Then there are some of the clipping issues that seem really unforgivable. I can live with the fact that the hair constantly clips through clothes and objects, but what really takes me out is when the head somehow pokes through the hair. That immediately ruined the Off The Shoulder hairstyle for me. Every time I would run with my character, the back of the head would poke through the hair. And I didn't even mess with the head sliders to make it abnormally large. It's the default head size that pokes through.
