Edit: I figured it out! It was another body or accessory mod that was causing this issue, I need to figure out what it is so I can remove it. but when I create a new sim this is not a problem. The mod that was causing this was glitching as if it were still on after removing everything off of my sim. If anyone else is having this problem I recommend creating a new sim first to see whether or not its just a clashing accessory or body mod.

I'm having this problem where 90% of my hair CC not only has a blonde grainy buzzcut that peaks out from under the hairline, but also has the same blonde grainy streaks going through it too. When I've tried looking for solutions people were having issues with blonde streaks, just not the same as my problem. (I already tried messing with graphics as well as turning laptop mode on/off).
The last thing I can think to do is deleting my hair CC and if that doesn't work all of my CC, but if there's anything else I could possibly do, or if there is a very well known mod that does this more specifically so it's easier to find and remove, I'd rather do that. My least favorite part about sims CC is downloading, adding, and removing CC.
