What does the term "carving" refer to in barbering?

Carving in barbering refers to a cutting technique specifically used to remove bulk from the hair. It involves using a razor or scissors to make precision cuts that create texture and shape, allowing the stylist to manipulate the hair more effectively and achieve a desired look. This technique is essential for creating layered styles or maintaining a clean, well-defined silhouette while ensuring the hair remains manageable.

The other options describe different aspects of hair services. Techniques for coloring hair involve the application of dyes and may include methods like balayage or highlights, which are unrelated to bulk removal. Creating curls typically involves styling methods such as curling irons or rollers, not bulk removal. Styling with products usually refers to the application of gels, pomades, or sprays to achieve various hairstyles, which is distinct from the cutting techniques used to adjust the hair's volume. Thus, the primary function of carving as a cutting technique directly relates to reducing hair bulk, making it the correct answer.
