Which part of the curl determines the amount of movement of the curl?

The stem of a curl is the part that influences the amount of movement in the curl. It connects the base of the curl to the end or the tool where the hair is wrapped. A longer stem typically allows for more movement and a looser curl, while a shorter stem results in a firmer curl with less movement. This ability to manipulate the stem's length and position is crucial for hairstyling, as it directly affects how bouncy or structured the final curl will be.

In comparison, the base refers to the area at the scalp where the curl is created, but it does not significantly impact the curl's movement. Tool diameter plays a role in determining the size of the curl itself, influencing its overall appearance, rather than its movement. Volume is more about the fullness of the hair rather than the specific dynamics of the curl's movement. Thus, focusing on the stem provides insights into the styling technique and desired outcomes in hair design.
