I know some of you may have seen me post things like “my hair is 3c and 4a” and been like what in the heck is she talking about? For those who may not know, curly hair is categorized on a scale from 1A being straight and 4C being the curliest or kinkiest. (Some believe that the scale should be reversed and type 4 hair should be first since its the most natural, but that’s another story for another day.)

The letters stand for strand thickness. a = fine/thin b = medium c = coarse
