The size of the curl will be determined by the:

The size of the curl is fundamentally determined by the diameter of the tool used during the curling process. When a stylist uses a curling iron or roller, the diameter of the tool directly influences the width of the curl produced. A larger diameter tool creates larger, looser curls or waves, while a smaller diameter tool results in tighter, more defined curls. This principle is crucial for hairstylists to understand, as it allows them to create specific styles based on the client's desired look.

While hair length, texture, and position of the curl can all affect the overall appearance and hold of the curl, they do not dictate the size in the same manner as the tool's diameter. Hair length may affect how the curls hang or show, texture can influence how well a curl holds, and the position of the curl can modify its visual effect, but the actual dimension of the curl itself is primarily influenced by the diameter of the curling tool. This knowledge is essential for achieving the specific styles that clients desire.
