In the attached image you'll see a hair model made by Apachii (http://www.nexusmods.com/skyrim/mods/10168/?) -a Skyrim modder. I downloaded all her hair files and have tried to reverse engineer her hair technique. It's extremely hard to replicate in Blender and I've probably seen every tutorial on the subject.
I suspect the best approach would be to use bezier curves and then convert the curves to a mesh. I have two problems with this:
how did she get the curves to lie so closely to one another without overlapping? Is there a way to snap bezier curves together so they hover above each at a set distance and never overlap?
how did she unwrap all those bezier curves so beautifully (see image below).
Here is a clearer image of the sort of hair technique I'm trying to master:
