Re: Sims 4 CC Hair Bald

It also happens with all my cc hairs. My base game hairs are fine, just the cc.

Read the CC carefully, it sounds like the hairs need a mesh. Might be a recolor of an expansion pack hair and, you don't have that pack or, it is a recolor of other custom hair which you don't have. the creators will state what it needs with the CC hair.
