What do conical rollers create when used in curvature shapes?

Conical rollers are designed to taper at one end, which creates a unique effect when used in hairstyling, particularly for generating curvature shapes. When these rollers are employed in styling, they result in a progression of curl diameters, meaning that the curls will vary in size from larger to smaller or vice versa. This variation occurs because the tapered end of the roller allows the hair to wind more tightly at one end and more loosely at the other, creating a natural, graduated curl pattern.

This graduated effect can enhance the overall volume and movement of the hairstyle, as the differing diameters provide dynamic texture. The ability to achieve this specific curling effect makes conical rollers particularly valuable for styles that benefit from a more complex, dimensionally varied appearance. In contrast, spiral curls, volume, and flat waves do not accurately describe the specific outcome produced by these rollers, which is why the result of a progression of curl diameters is the appropriate answer.
