3A hair is made up of well-defined and springy curls that have a loopy, “S” shaped pattern. Their circumference is the size of a piece of sidewalk chalk. 3A ringlets have a fine to medium texture. This curl type benefits from lots of body and movement, but is prone to frizzing and dryness.
Type 3B. Hair type 3Bs have springy ringlets with a circumference similar to a Sharpie marker. This hair texture can get dry, so look for styling gels that have humectants in them to attract moisture to strands.
3C curls are tight corkscrews that range in circumference from a straw to a pencil, like you see her on Yara Shahidi. Strands are densely packed together, giving way to lots of natural volume.
