Step 1: Sketch out a head for the base guidelines.
Step 2: Draw out the hairline.
Step 3: In this step we will draw out uneven bangs in the middle of the head, starting at the baseline. Then you will add longer pieces of hair to the sides.
Step 4: In this step we will round off the head top. This portion will be the headband.
Step 5: Add some hair to the back of the head starting from the headband. Make sure the back of it is about level with the front hair.
