Which part of a curl determines its mobility and movement?

The stem of a curl plays a crucial role in determining its mobility and movement. This part is the section of the hair between the base (the point of attachment to the scalp) and the circle (the curled end of the hair). The stem can vary in length, and this directly influences how the curl behaves.

A longer stem typically allows for more movement and flexibility, resulting in a softer, looser curl. On the other hand, a shorter stem can create a tighter, more structured curl with limited movement. This characteristic is essential for stylists to understand, as it allows them to manipulate the curl's mobility depending on the desired outcome.

Understanding the function of the stem is fundamental in haircutting and styling, as it helps hairstylists manipulate hair creatively while ensuring that the desired style can be achieved effectively. The base, circle, and size refer to different aspects of the curl, such as its foundation, the shape, and the overall volume, which do not directly control how the curl moves.
