Finger waving is the technique used to achieve smooth curls, characterized by its elegant S-shaped waves that create a refined and polished look. This classic hairstyling technique involves bending and molding the hair into waves using the fingers and a comb, along with the application of a setting lotion or gel for hold. The process is done by creating alternating waves that are pinned in place until they set, resulting in smooth, defined curls that can be blended or showcased.

While other techniques can create curls, they may not provide the same seamless, vintage aesthetic that finger waving offers. Twisting tends to produce a more textured or spiraled curl rather than the smooth appearance sought after here. Pin curls, although effective in creating curls, usually result in a more bouncy and voluminous style, which may not embody the smooth quality intended by the question. Flat curls, although possible, are not a standard term or technique recognized in the same context as finger waving. Thus, finger waving stands out as the technique that best achieves smooth curls, making it the correct choice.
