Hair type 2 is generally categorized into 2a, 2b, and 2c based on the texture and pattern of the waves. Here's a quick overview to help you determine:
-
2a: This type is characterized by loose, beachy waves that have a slight bend with a fine to medium texture. The waves do not have much definition and can be easy to straighten.
-
2b: This type has more defined waves that tend to be medium in thickness. The waves form a more "S" shape and can appear more frizz-prone, especially in humidity.
Since you describe your thick wavy hair as having a u shape when it curls, it may lean more towards 2b. The thicker, more defined waves suggest a stronger wave pattern, which is characteristic of type 2b hair. If your waves are more subtle and looser, you might categorize it as 2a. Ultimately, the distinction can also depend on individual hair characteristics, so it may help to assess your hair’s overall texture and wave definition.
