Hair CC - Weird Coloring

Hey guys,

I wanted to know if anyone else has this problem and if you can maybe help me? For some reason I have some Custom Content Hair that has weird coloring on it. It doesn`t happen with a lot of my hair cc, but it`s still annoying and I can`t find out what causes it! I added a picture with examples, so you can see what I`m talking about.

Thanks in advance for any answers :)
