Why was it that in anime, manga, and novels, when a character's abilities increased, their hair would often grow longer? What was the reason?

Why would in those anime, manga, and novels, when one's abilities became stronger, such as taking some medicine or using some kind of magic, one's hair would grow longer? One of them was so bad, but basically, as soon as their abilities became stronger, their hair would grow longer.

Answer 1

This was actually a widely circulated routine, known as "combat power = hairstyle." In anime, manga, and novels, characters would often have their hair grow longer or change color to indicate that their abilities had improved or that their identities had changed. This setting may be related to the traditional Japanese culture of "", which believes that the fate of people is related to hair. However, this routine might not be applicable to all works. After all, the setting and creator of each work were different. If you are confused by this setting, you can try to understand the cultural background and symbolic meaning behind it. In addition, if you like the setting of adding points to become stronger, you can read the novel "I Will Add Points to Cultivation". The setting of adding points to become stronger might give you a good reading experience. I hope you like this fairy's recommendation. Muah ~😗
