I had a tutorial a little while back on this...but I cleaned off my computer and lost the link...
However, I remember what they basically said. She said to remember that the hair usually forms locks, and its ok to "blob" some pieces of the hair together and emphasize the texture with several lines (the "strands" of the hair) done in different shades. You don't have to draw
every strand; when you look at someone's hair, do you see every strand of their hair? Nope. In fact, a lot of the hair is probably going to be clumped together a bit.
But that's just from a tutorial I looked at...and I dunno if I really explained it well. If you really want specific help in your art, try posting a sample of what you've done so everyone can see exactly what you've done so far and what can be improved ^^.
ahaha i get what you say, but the drawing "every strand of hair" is to get the flow and motion of it. It'll naturally form the clumps. Once you get the clumps of many drawn strands, you can create a second layers with a slightly (i mean slightly) darker color and have it be the underlying color. The best way (if you're using Adobe Photoshop since I dont know anything else) is to set the brush (assuming using a tablet here though) to do the.... the thing there it colors depending on what your foreground and background colors are..... then you'll get variation when you draw your strands and can get the subtle "this is a highlight turning darker" The style you're looking for will also determine not only how many strands you draw but where you draw them. Just at the tips? just tips and roots, or all the way through.
