Hair keeps using skin texture (Solved)

Hello, and it's been a long while since I've done any hair for Sims 4 (that I in fact have forgotten some stuff).
I've been trying to port a hairstyle, but even after following these tutorials:

sims4studio.com/thread/134/mini-tutorial-sims-hair-components
sims4studio.com/thread/2091/tutorial-01-hair-uv-unwrap

The hair keeps showing the skin texture instead of the hair (and I have dealt with the uv maps and uv_0 is within the correct space):

Another thing that's bothering me is the fact that none of the tutorials have mentioned is setting the materials and such in Blender for hair:

(which is why, when I tried to do it like other EA Hairstyles, that's when it only shows the skin texture)

So, unfortunately, I'm stuck, and I can't remember how I got it to work previously, so, can someone please help?

Thanks!
