I think with the new patch that came out, a couple male hairstyles were made available for females. The CAS thumbnails didn't have the CC icon next to them, so I know it wasn't some CC I had forgotten (plus I haven't purposefully downloaded gender-swapped hair).
The first one.
The second one has a weird outline around the ear.
And for the males, is this hairstyle new?
I know we have a close-shaved one already, but with this one you can see the short hairs (easier to see with blonde hair).
Here's the close-shaved one we already have.
But of course I could be totally wrong about it.
