Why is my light colored CC hair flaky?

So I only just recently got this problem. Anytime I use light colored (Blonde, Light Brown, etc. you get the jist) Custom Content hair it’s “flakey”. At first I only had a problem with one cc hair so I thought it was just a mod issue. But then today while using another cc that I use all the time that I never had a problem with, all of a sudden today is having this problem. It has like mini bald spots. I can’t attach pictures for whatever reason but I hope y’all get what I’m saying. The only color that is working is black. It’s weird cause before this problem the hairs worked fine but all of a sudden it doesn’t. Plz help.
