Curls are a type of hair texture characterized by spirals or waves. They can vary in size from loose waves to tight ringlets and are often classified into different types based on their shape and pattern. Curls are influenced by genetics, and the shape of the hair follicle plays a significant role in determining whether hair is straight, wavy, or curly. Curls can be styled in various ways, including using heat tools like curling irons or by employing techniques such as braiding or twisting. Many people with curly hair use specific products, such as curl creams and gels, to enhance and define their curls while reducing frizz.
