But hair is a shape... :) If it's an anime character, then I guess "solid" hair is what you're looking for rather than the more realistic transmapped stuff. The only advice I can give is to practice with Wings, and get good at it - which is how you get things to look like the shapes in your imagination, basically, although I realise that doesn't sound very helpful. Wings will do the mirroring for you, I'm sure. What I often do is model the whole object, then choose the best half, cut it down the middle, mirror the remaining half and join them back together. The folks in the Wings forum may be able to remember where Pakled's hair tut was, if he can't...
