Here is a pic of what I'm talking about:

1) Black ink with a brush or crowquil - you add the black, brushing into the highlights, but leaving them white obviously. - takes time to master, but most realistic one to figure out.

I don't think it takes that long. Looking at your sample pic, I can see the artist's steps:
1. Visualize his hair as separate long flat strips, like flaps of cloth. Draw them as such in pencil sketch.
2. Mark out areas that will be most direct to light and therefore will be areas of shine.
3. Draw in black with brush or marker. Leave white as negative space at the areas where hair will shine.
4. Draw in some long loose strands for accentuation.
5. In Photoshop, draw in additional white areas and lines. Easier than white ink.
