/jp/ - Otaku Culture

I visited /ic/ for the first time and asked them if they could help me with this, but I didn't get much of an answer so I'll just repeat it here.

I really suck at coloring hair. I really don't know what I'm doing here, and I'm just kind of winging it since I'm still very new to drawing in general. Whenever I look at references I have no idea how they come up with their shading and it just looks so random to me. This is basically all I know how to do though. Could anyone give some pointers or share some guides?
