It is to suppress the sweat and steam generated by the thick hair on the top of the head when wearing the hood, and reduce the discomfort caused by the sultry heat to the wearer.

This hairstyle, called Dai Yue, is not limited to samurai. It is one of the most common hairstyles for Japanese adult men in ancient times.

The earliest record of this head type comes from the Jiupin diary Jade Leaf written by bureaucrats from the late heian period to the early Kamakura era. Among them, on July 8, Anyuan II recorded: "Since the film is cheap, Shi Zhongqing's fingers are not straight, the moon is too bitter and his face is extremely damaged." So this hairstyle came into being at the end of Heian.

With the collapse of heian period's legal system and the rise of martial arts, war has inevitably become one of the best symbols of Kamakura era and Muromachi era. In the fifth volume of Taiping Ji, there is a record of the generation of Yueshi. By comparing the results of the scrolls, we can see that in Kamakura era and Muromachi era, the Moon Dynasty was mainly used in the battlefield.

With the arrival of the Warring States period (Antu Taoshan era), the demand and frequency of war increased greatly, and people began to pull out the hair on their heads with tweezers. Later, with the long battle on the battlefield, some soldiers suffered from scalp inflammation due to sweltering and sweating, and shaved their heads instead of pulling them out with tweezers, and the Yue Dynasty became the mainstream.

Extended data:

At the end of the Warring States period, with the great victory of Guanyuan and Dongjun, a relatively stable Edo era was created under the rule of Tokugawa shogunate after the Battle of Osaka and Yuanhe. During this period, except for ministers, the Yue Dynasty gained popularity and became the choice of adult men in ordinary soldiers and even civilian families.

The Meiji Restoration with Emperor Meiji as the core overthrew the rule of Tokugawa shogunate for a hundred years. With the whole westernization, 187 1 issued a sword scattering order, asking the samurai to spread their hair and take off their swords. With the end of the samurai era and the demise of the samurai class, the leaders of the Dai Yue Dynasty withdrew from the mainstream vision.
