"Sectioning" in hair services refers to the process of dividing the hair into manageable parts to facilitate styling. This technique is essential for both precision and control during various services, including cutting, coloring, and styling. By sectioning the hair, a stylist can work on smaller portions at a time, ensuring that the desired results are achieved evenly and effectively. This method helps the stylist maintain organization and focus, which is particularly important in complex styles or when a consistent result is required.

Other options do not accurately capture the concept of sectioning. For instance, cutting hair in a straight line pertains specifically to a cutting technique, using product to define curls focuses on styling methods related to product application, and applying heat to the hair is associated with thermal styling techniques. None of these options encompass the broader idea of organizing hair into segments for more manageable handling during hair services.
