Curly hair is primarily characterized by having an oval or asymmetrical follicle shape. This unique shape influences how the hair strand grows and how it curls. In curly hair, the oval or asymmetrical follicle causes the hair to bend and twist rather than grow straight. This results in the hair texture being coiled or curly, which is opposed to straight hair that typically arises from round follicles.

The keratin structure in curly hair also forms a pattern influenced by the shape of the follicle. Because of this oval or asymmetrical follicle shape, the strands can vary significantly in curl tightness, leading to a diverse range of curly hair textures.

The other options do not accurately reflect key characteristics of curly hair. For instance, saying that curly hair grows in a circular pattern does not align with the reality of its growth process; rather, that describes straight hair. Round follicle shapes typically relate to straight hair as well. The description of hair as straight and fine does not connect to the nature of curly hair at all.
