“…he maintained a “conk” hairstyle, which was a way of chemically relaxing
naturally kinky hair. The style was popular among African American men from
the 1920s to the 1960s, despite the risk of chemical burns and the high
amount of care necessary to maintain it. In his later years, as he reflects
back on his youth and the culture of the “cool cats,” Malcolm no longer
sees this as simply an aesthetic choice.”
