A texturizer or perm works well to achieve curly hair for black men. The look is also achievable through manual curls, such as setting curls by wrapping them around drinking straws.
Texturizers, perms and curl reconstructors are all methods of creating curly hair through chemical means. Although chemical curly hair procedures are doable at home, they are often executed in a salon setting. The look usually lasts for months.
Curling black male hair with a manual method does not last as long as a chemical procedure, but it is a natural, cheaper method that does not cause damage to the hair or scalp.
