Miss Gu wants a drastic hair makeover. She starts off cutting off her pigtails to shoulder length herself. The long bangs are left untouched. The stylist evens it up to shoulder length. The nape is buzzed and shaved with razor.
Then, her hair is cut into a long bob. Next, the bob is reduced to chin length, with the front hair left a bit longer. Finally, the thick bangs are cut very short across the middle of her forehead, at her personal request to be fashionable.
Video has lots of style presentation at each step.
