Comb bangs neatly with a comb to make bangs smoother. Don't stick them together. Then comb the bangs into 37 or 28 points.
Use a curling iron to roll bangs at an oblique angle of 45 degrees, and then let the curling iron be fixed for a period of time, or use a hair dryer to heat and blow, shape and increase the curl.
Take off the roll paper, gently comb the bangs with a comb, and comb the bangs into three or seven points. The figure-of-eight bangs are thin, transparent and light.
