Depends on how you go about it, as it's all about workflow and where/how you start to draw the line. Generally you want to pick the closest corner/endpoint starting from the forehead's center for almost anybody's hair. For Sunset, the closest corner is the top of the long, sweeping bang going over her ear facing the viewer. You finish that, add the upper curve above it, draw the other side, then you add the center twirl, the sidebangs over her ears, and then the back is just a series of curves. Rest is practice.
