Protective hairstyle
Hair and hairstyles are part of the history of race on Earth.  In some places, for example the United States, employers have told employees, usually African American employees, to go home and change their hair or else be fired.  People with African hair must take time and spend money to change their hair so it looks like a white person's hair.  Some places have passed Creating a Respectful and Open World for Natural Hair (CROWN) laws.  CROWN laws are anti-discriminiation laws.  This means an employer cannot fire an employee for wearing a protective hairstyle and cannot force an employee to try to make their hair look like a white person's hair.  For example, New York State added rules about protective hairstyles to its human rights law in 2019. The United States Congress passed a CROWN law for the whole country in 2022. The law says, "In a society in which hair has historically been one of many determining factors of a person’s race, and whether they were a second class citizen, hair today remains a proxy for race. Therefore, hair discrimination targeting hairstyles associated with race is racial discrimination."
