In an interview with Radio Free China, Chinese human rights lawyer and activist Teng Biao said that shaving the heads of people held in Chinese prisons and detention centers is a regulation practice, suggesting that local authorities likely profit from it. “There are no rules about how to deal with the hair of people in prisons – it’s very difficult to supervise or place restrictions from above on how to deal with hair that has been forcibly removed,” said Biao. “As a result, this has also created an environment in which [officials] are not going to turn down the economic benefits of hair that has been shaved off of people in government camps.”
