Hello! Hair can be tough. I’ve made a little guide for you on what I like to do when I’m stuck trying to come up with a hair design for my portraits. Basically, I like to make a new layer and get a BIG marker-type brush to draw in some abstract-looking volumes. Focusing mainly on how I want the silhouette of the hair to look and being loose with the volumes to give me lots of options to pick and choose from when I go to do the line art. Remember that hair usually follows from an origin or a part line. For this character, it seemed like his hair was all flowing from the origin point on the back of his skull. So I made the strokes of my marker drawing flowing out to the front and sides from there. After you’re happy with the marker drawing, just drop the opacity and start refining the volumes. Hope that helps!
