Sims 4 Hair/CC Problem

It's not my computer and I know that for an absolute fact. I wiped my computer clean because there was a bunch of * on it from when my mom used it, viruses and junk that I could not get off my laptop. But before I did that I already had The Sims 4 on it and I remember having this problem at one point but I figured out how to fix it and the only problems I ever really had was broken mods or the occasional lag and crash. And I do not know if it is all hairstyles. So far I've only placed two Sims (male and female) within the world, and both of their 'everyday' hairstyles are Stealthic. 90% of my mods are only from featured artists from The Sims Resource.
