I got a couple of requests for a hair tutorial, so...ta da! This is for more of a quasi-realistic look, and you can omit step 6 if you're working with line art that doesn't permit those strand strands. Hope you find this helpful!

Questions? Comments? Requests for other quick, serial-like tutorials? Message or comments!

After reading some comments (or lack thereof), I'd like to say that I didn't put words on it mostly because there's no one way of going about things.

In essence, ths hair making is just mostly a layering process.

Hm, well being armed with a pressure-sensitive tablet, I begin with the basic shape of the hair. A few, thicker locks here and there, accordingly placed in the manner that fits your picture best: all done in a midtone color. The tapered ends come naturally if you use a tablet, but if you're a mouse user, you might have to spend some time refining it.

Then, I build up shadows using a smaller brush and a darker hue. This continues for about three to four shades dark.

I repeat the process with the highlights, building color up, but only about one or two shades bright.

Then the final touches come in: with a burn tool set to around 7 in opacity and a brush size greater than fifty, I burn in subtle shadows here and there, just to make them more dramatic. However, the main focus could be the colors you put there before. I don't recommend depending on the burn and dodge tools for any sort of coloring as things then to come out plasticy in appearance.

Repeat the process with a big brush/low opacity setting for the dodge tool to bring out more luminescent highlights.

Hope this was helpful!
