- 1). Brush bangs forward over your forehead. Use the end of a rat-tail comb to split the bangs in half horizontally. Pull the upper layer of the bangs back toward the crown of your head and pin. You will thin the bangs in two separate layers.
- 2). Hold the thinning shears vertical to your head or parallel to your bangs. Open the scissors to reveal a 1-inch gap between the blades.
- 3). Glide the scissors through the hair to shave the bangs, starting in the center of the bangs, about 3 inches from the scalp. The blades of the scissors will cut the hair; there is no need to close the scissors during the process.
- 4). Remove as much hair as you need to for the first layer by moving from side to side. Release the second layer and repeat the thinning process.
