Type 3b hair can be straightened, but it's definitely a chore. Type 3b hair generally isn't particularly shiny and its texture can be quite coarse.

Type 3c hair has voluminous, tight curls in corkscrews, approximately the circumference of a pencil or straw. The curls can be either kinky, or very tightly curled, with lots and lots of strands densely packed together. Getting this type of hair to blow dry straight is more challenging than for 3a or 3b, but it usually can be done. The very tight curls are usually fine in texture.
