Why are prisoners shaved hair?

I. This is due to a kind of punishment in China's ancient times, in ancient times, it is expressed as an insult to the personality of the prisoner. In ancient China since the Qin dynasty, shaved head is a kind of punishment, called scalping, refers to shaving the prisoner's hair, beard and sideburns this is a kind of humiliation punishment, intended to degrade the prisoner from the personality, in the spirit of the prisoner to be struck. This was often employed as an additional punishment to the sentence of imprisonment. \x0d\2, in fact, prisoners shaving their heads is a long-standing unwritten management rule in domestic prisons. This is because it not only facilitates prison management (e.g., hygiene, preventing items from being hidden in the hair), but it is also easy to distinguish. Once a prisoner escapes, it is easy to recognize and spot the target when arresting him, and even if the criminal wears a wig as a disguise, he can be easily detected. I'm afraid the necessary measures were taken based on this idea in the first place. Baldness, like serving a prison sentence, is a form of punishment for prisoners, warning them not to engage in criminal activities in the future. The "humanistic care" for prisoners is not reflected in whether or not to keep their heads bald, but rather, we should be genuinely concerned about their rehabilitation activities, to purify their minds, and to help them reintegrate into the society and start a new life. \x0d\ Currently with the progress of judicial civilization, this traditional practice is gradually changing. Haikou, Shanghai and other places have abolished this mandatory requirement, prisoners can stay boarder, which also reflects the humanization of prison management towards. \x0d\3, from now on, male inmates in Shanghai's prisons can independently choose three types of hairstyles: flat head, inch hair and bald head. The Municipal Prison Administration recently officially issued the Notice on the Range of Hairstyles Independently Selected by Sentenced Personnel, and began to implement it in all prison centers and the General Hospital of Prisons. \x0d\ In early March 2004, the Municipal Prison Administration began to gradually implement the Ten Measures for Civilized Law Enforcement in all Shanghai's prisons, seeking to give sentenced persons more freedom in terms of their personality rights, health rights, communication rights, personal legal property rights and learning rights on the basis of not contradicting China's Criminal Law. The ten measures include "the inmates can choose their own hairstyles within the scope of the regulations". At the same time, the Municipal Prison Administration also held a hearing on the "ten measures", and in the pilot units to gradually implement.
