Girl’s hair looks like waterfall

this iPad drawing shows a beautiful Japanese young girl sitting by herself, her long hair is as beautiful as waterfall. I remember in Hong Kong there is a shampoo commercial: a young man is doing hiking with his girlfriend and crossing a beautiful waterfall, suddenly, a beautiful blonde girl in her swimming suit taking shower by the waterfal behind them , his girlfriend asks “ Honey, what are you looking at?” The guy says”I am looking at you, your hair is as beautiful as waterfall!”
