It is part of the curly hair classification system, which categorizes hair types based on curl pattern and texture. The 2C hair type is considered a combination of wavy and curly hair. 2c hair  forms loose, well-defined S-shaped curls that may be more prominent in some areas of the head than others. The curls are relatively tight but still have a noticeable wave pattern. 2C hair often has a moderate amount of volume. It may not be as voluminous as some other curly hair types, but it still has body and bounce.

Can you explain what is 2C hair ?
