What tool is commonly used for creating finger waves besides your fingers?

The tool that is commonly used for creating finger waves, in addition to your fingers, is a comb. The comb is essential in this technique as it allows for precision in creating the wave pattern; it helps to shape and define the waves by combing and manipulating the hair into the desired S-shaped curls. The fine teeth of the comb are particularly useful for detailing and achieving the smoothness needed for the finger wave style.

While brushes, scissors, and clips serve various purposes in hairstyling, they do not play the same pivotal role in the creation of finger waves. Brushes are generally used for smoothing and detangling, scissors are for cutting hair, and clips are more often utilized for sectioning hair rather than for shaping it into waves.
