A short debrief on hair types, in the event you need a refresher. Like we noted, hair is categorized into types from 1 to 4, each with three smaller subsets noted as A, B, or C. Hair types aren’t scientific terms (so this isn’t a set standard crafted up by derms or researchers), but it’s pretty universally accepted among hairstylists, trichologists, and even many derms themselves! (It was actually made famous by Oprah’s hairstylist Andre Walker, so we have another thing to thank Oprah for.)
As a rundown: Type 1 is straight, with the variance usually coming to how flat your hair lies. Type 2 is wavy, with the major differences depending on how loose the S-pattern is. Type 3 is curly, which changes depending on how tight the curl is. And Type 4 is kinky or coily, which changes depending on whether the shape of the pattern is more zigzag or springs.
