What was the evolution of hair styles in ancient Japan?

At the earliest time, Yoko Hyogo was actually just a derivative of Hyogo. Later, after changes, it began to be unique. It is characterized by a wide bun at the back of the head, which looks like a fan from the front and looks like a beautiful butterfly from the back. Such a beautiful hairstyle can only be combed out by senior girls like based. They want to tie all kinds of hairstyles on the bun, and in order to support the unique shape of the bun, they have to string iron wires on their hair to fix it. Later, after some changes, the "Ida Hyogo" derived from Yoko Hyogo in the late Edo period was born. Ida Hyogo has increased the height of bun on the basis of Yoko Hyogo, which makes the front look higher and the whole look more grandiose.
