A corrective color service is defined as a process to adjust or alter the hair color. This service is typically sought when a previous coloring has resulted in undesirable outcomes, such as incorrect shades, uneven application, or damage to the hair that affects its color appearance. The goal of a corrective color service is to bring the hair back to a more natural or desired hue, ensuring an even and aesthetically pleasing look.

In contrast, the other options relate to different aspects of hair treatment. For example, thinning hair generally concerns reducing volume without altering color, and adding color highlights focuses on enhancing the existing hair color rather than correcting it. Maintaining existing color involves ensuring that the current shade persists, which does not encompass the adjustments made during a corrective service. Therefore, the correct identification of a corrective color service as one that aims to adjust or alter the hair color is essential for understanding the nuances of hair coloring techniques in professional practice.
