Type 3 hair includes lightly curly to very curly hair patterns that are well-defined and springy. Curly hair has a lot of body and can be easily styled in its natural state or straightened with a blow-dryer. Despite its appearance, type 3 curls are soft and fine rather than coarse.
Type 3a curls show a definite loopy "S" pattern that is well defined and usually springy. Type 3a curls have a circumference the width of a piece of sidewalk chalk. Generally, this hair type can be easily straightened or retexturized. Type 3a curls are more prone to frizz and losing definition than Type 2 hair.
Type 3b curls are more voluminous and have a smaller circumference than Type 3a curls--the size of a Sharpie marker. Type 3b hair is not as shiny as Type 3a curls, and the texture can be coarse and dense.
Type 3c curls resemble tight corkscrews and are approximately the circumference of a pencil or straw. Type 3c hair tends to be higher in density and coarser than type 2 or 3 hair, giving it more volume. Type 3c curls are finer in texture, though packed tightly together on the head.
