What is the name for curls created using a roller placed on base?

Curls created using a roller placed on the base are referred to as volume curls. This technique involves using rollers that are positioned directly at the base of the hair, which lifts the hair away from the scalp and creates a fuller, bouncier appearance. The placement of the roller on the base encourages maximum volume by allowing the hair to expand and fill out.

The other terms describe different types of curls or techniques. Flat curls generally refer to tighter, more defined curls that lie closer to the scalp rather than adding volume. Cascade curls usually describe a rolling effect that creates a soft layered look but does not specifically emphasize base placement for volume. Spiral curls, on the other hand, are characterized by a more defined, coiled shape and may not focus on base placement for volume enhancement.
