CC skins/eyelashes show up but not hair etc.?
So, I have a problem. I have downloaded some skins and eyelashes and they show up in my game and work. I know all the basics to downloading stuff, though with sims 4 I might still be a bit of a newbie (have played Sims 3 and downloaded lots of CC). But yes, to the problem - I downloaded some hairs on The Sims resource, I am sure they were for Sims 4, and the mesh needed was included (and it can't be about the specific hair just working because they worked just well in my friend's game) BUT they did not show up in the game. I have tried to search for the answer online, but couldn't really find anything since it's not all of the CC that won't work, since the skins and eyelashes do work. Help would be much appreciated and I can try to provide more information if necessary (also apologies for grammar mistakes, English isn't my first language).
