Why do Asian female characters dye a strand of hair in Hollywood movies?

It's just a coincidence of role setting. In my opinion, Asian women in Hollywood movies like to have long, straight and smooth hair, most of which are pure black.

In recent years, the number of Asians in Hollywood movies has gradually increased, which also shows that Asians are becoming more and more distinctive in movies. In the eyes of foreigners, Asian women still have the mysterious oriental flavor hundreds of years ago, but they also have a hint of indifference that cannot be approached. Hollywood movies usually give Asians a distinctive hairstyle and hair color, and dye a strand of hair mentioned in your topic. These are all designs that the director wants to highlight the uniqueness of Asians in disguise.

Even in the case of the same dress, the director is more willing to design some "oriental colors in their minds" for Asians. Dyeing a strand of hair and wearing a hairpin are common habits of Asians. Emphasizing the particularity of oriental colors will also give the audience a unique feeling.

The hair style commonly used by Asian female characters is straight black hair, which is as standard as black explosive heads in Hollywood. Liu Yuling, a famous Asian in Hollywood, is a perfect representative. She has a Hollywood face and unique Asian beauty, which is largely due to her image.
