So many things that can go wrong .... Is the object colour for the SkinHead material white, also? If it isn't, that might explain why the brows and the rest of the head don't match. Which transmap are you using for the upper eyebrows? Make sure it's a Victoria head transmap, because Posette's transmaps are different. Is Victoria's BrowsGone dial set to 0 or 1? At a value of 1, the upper eyebrows are hidden inside the head, and no amount of transparency adjustment will help.
