What result does the overlap (croquignole) technique produce?

The overlap (croquignole) technique is commonly used in hairstyling to create undulating waves and curls. This method involves wrapping hair around a curling rod or iron from the ends up to the roots, with the hair overlapping itself as it goes. The result is a more natural-looking wave pattern that gives body and texture to the hair. The technique effectively creates movement and bounce, which are characteristic of undulating waves and curls, making it ideal for styles that require a soft, flowing appearance.

Other techniques would produce different effects: straight hair would not result from overlapping but rather from smoothing methods; ringlets would require a specific curling technique that tightens the curl rather than allowing it to flow in waves; flat waves might involve a different styling method that does not emphasize the same volume and texture generated by the overlap technique.
