What is the process of shaving the sides of the neck and across the nape described as?

The term "neck shave" specifically refers to the process of shaving hair from the sides of the neck and across the nape, which is the area at the back of the neck. This grooming technique is essential for achieving a clean and well-defined look, particularly in styles where hair is kept short around the neckline. By using proper techniques during this process, barbers can enhance the overall appearance, providing a polished finish to the haircut.

While "neck trim" could imply any sort of adjustment to the hair in that area, and "nape contour" might focus on shaping rather than the act of shaving, the phrase "hairline shave" more closely relates to defining the hairline. However, "neck shave" encompasses all the actions taken to remove unwanted hair from the neck and nape, making it the most accurate term for this specific grooming process.
