1B hair, on the other hand, is the most common hair type. It is straight and flat but has some volume.
Type 2a hair tends to lie flat at the roots and starts to form waves at eye-level. This gradual change in texture can make hair look inconsistent. The shape of these strands don't take on the slight curl pattern of 2c hair types nor do they have the definite wave texture of a 2b hair type.

Type 2C. Type 2C hair has defined waves that start at the roots, and is thicker than the other subcategories. This hair type starts to form loose spiral curls and has that “S” shape. Type 2C tends to be the most prone to frizz of the Type 2 category.
Type 3a hair is characterized by well-defined spiral curls that are typically the size of a piece of sidewalk chalk. Although the circumference of 3a curls is wider than that of 3b and 3c hair, it can be difficult to tell the three curl types apart.
