On Vic4's, one small problem on close-ups is the fact that their eyebrows are drawn on the face's bitmap. Quite often though, I success at creating a decent brows transparency map using steps I still can't reproduce using Gimp.
Then, I'm using this small hack:

The Value2 of the Math node lets me keep a kind of overall roughness control, while the brows transparency remains completely white

That way, I get a correct effect: slightly reflective skin but the brows remain "dry". In my personal case, when my brows is the last part of the body that becomes glossy, that means that I'm 100% sweaty... gasp 

Here, I'm using Swam's Betty Hair, which  i find more than honest for a transmap hair.
