What are pin curls sliced from a shaping and formed without lifting the hair referred to as?

Pin curls sliced from a shaping and formed without lifting the hair are referred to as carved curls. Carved curls involve taking a section of hair, usually from the top or center of the head, and slicing through the curl while keeping it on the scalp. This technique helps create a defined curl shape without separating it from the head, allowing for more control over the look and ensuring the curl maintains its structure.

The term "carved" specifically indicates that the curl is not just twisted or styled loosely; it is meticulously shaped to achieve a certain form, characteristic of pin curl techniques. This method also helps to maintain the integrity of the curl, making it ideal for achieving polished hairstyles that require a bit of hold and definition.

Other terms such as twisted curls, layered curls, and spiral curls refer to different curling techniques or styles and do not accurately describe the specific process of slicing and forming curls as outlined in the question.
