You shouldn’t. BTW, you don’t need re-colors (that’s only if you want their custom hair colors outside of what s in game) and you do need the mesh (most hairs don’t require a mesh) and all the creators will link the mesh if needed. It doesn’t happen often with hair. Here’s some of my favorite creators:

https://madmonodls.tumblr.com ( I like the ultra violet skin) default only means every sim will have the skin. Non default means you can place the skin on sims (it’s in the freckle section).
