Hello! I usually use Pooklet’s textures; they released multiple versions, but you can find them all in this post. For curly hairs, I use Nymphy’s. I’ve used textures from Io and Cazy in the past, but in those cases I just took the textures from hair files, since I couldn’t find them posted anywhere.
In my game, I also like hairs retextured using twists and dreads (like the ones from Trapping’s DreadsLong 3to2 hair).
Hope this helped!
