How is hair coloring done in shojo manga (examples given)?

I've always wondered how coloring is done on the hair of black-and-white shojo characters, such as:

L (very bottom) from Death Note: http://blog.newsarama.com/gallery/albums/userpics/10002/deathnote2.jpg

See how their hair is mostly black, with white 'shines'? I've always wondered if there was a technique to doing that. Is it just a matter of stopping the ink at some point in the hair? How am I supposed to know where to stop? Is this type of coloring done traditionally or digitally?

Please give as much relevant information as you can. Thank you~!How is hair coloring done in shojo manga (examples given)?
Yeah, it's pretty much just a matter of first sketching the picture, then lining it. When drawing the lineart, I assume they also line the outlines of the shine, and then they just fill in the appropriate outlines while leaving the space inside the shine outline white. I'm pretty sure they don't just haphazardly fill in the hair while leaving parts white -- they outline it, and then just fill in any area that's supposed to be filled in.



You know where the shine goes by learning how the shine works, I guess. Like, look at your own hair, and notice where it shines. With practice, you'll figure out where the shine would be without having to use a reference. (You can also bluff your way through it by just putting shine where it looks right.) As a semi-random example, look at this page:

The artist is drawing in rough pencil and is not aiming for a manga or anime style, but look at the shining areas in the hair. Instead of blending into the shine, you'd outline the shape of it sharply, and then fill in the dark parts. This page illustrates it, sorta:

See, in the second picture, the artist blended and softened the hair to make it realistic. In the first picture, though, it's similar to how a comic artist might draw it. The shine is white and the rest would be black. (It isn't really black in the picture, but that's because it was done with a regular graphite pencil. Imagine that it's been inked, so it's black and white.)



Japanese mangakas generally use traditional inking styles, although there are exceptions.





EDIT: Oh yeah, just wanted to point out that Death Note is shonen, not shojo. Shojo is intended for a female demographic; Special A is clearly shojo. Death Note, while it has lots of female fans as well, was intended for a male audience and was published by Shonen Jump, which strongly implies that it is shonen. (Special A, on the other hand, was published by Hana to Yume. Hana means flower, to means and or with, and yume means dream. So it basically means ';flowers and dreams.'; Sounds girly, right? Obviously shojo.)
