Alpha issue around eyebrows?

I've been working on converting some TS2 cc the last couple of days, but while doing it, I noticed some problems around the eyebrows (and a little bit around the hairline). Someone on tumblr said it's because of alpha issues, and they didn't know a way to fix it without spending hours on perfecting every single little detail. I'm still such a newbie to making content, so I wanted to see if anyone knew a way to fix it (or at least make it less noticeable), before I decide to just scrap the idea completely 

Here's a picture, highlighting the problem 



Thanks
