I should go a bit further. Sam Cooke made a conscious decision to stop processing his hair as an African American man. Had nothing to do with fashion trends or what have you. Malcolm X also spoke out about it as a prominent black man during that era. James Brown and them went on for several more years and stopped in the late 60's.
Marvin stopped conking his hair around that same time [[1964-65).
