If you choose texture id 470 (show hair) it looks like crap on most of them, but the hair-only styles that did seem to look okay (and I use that term loosely) are bright red in the screenshots, for enhanced visibility.
Almost none of the styles will look exactly like my screenshots when you initially add them to your barb. You'll have to mess with the face settings to make them fit and look decent: mostly face width, depth, top, and/or mid, but other settings can affect them also, like forehead and cheekbone. Just experiment until you like the results
Panda seemed to have the best results overall.
Most styles probably won't look good on other species of barbs since each head model sits a bit differently on the characters frame.
