According to the query of China Poetry Network, we know that the poem with the longest hair is the ancient poem Qiupu Song, which was written by Li Bai in the Tang Dynasty. The first sentence: "White hair and three thousands of feet", which is a wonderful exaggeration, is simply unreasonable. A person's hair rarely exceeds his own length, so White Hair written by Li Bai is the longest poem describing hair.
Hair refers to the hair that grows on the head. Hair is not an organ, so it does not contain nerves and blood vessels, but cells. Hair is mainly used to protect the head. Soft and fluffy hair is elastic, which can resist light collision and help head sweat evaporate. On average, each person has about 654.38+ million hairs. Of all the hairs, the length of hair is the longest, especially for women with long hair. Some can grow to 95 ~ 100 cm, or even 150cm, but generally it will not exceed 200cm.
