What is the technique called when parting a haircut in the opposite way it was cut to check for precision of line and shape?

The technique used to ensure the precision of lines and shapes in a haircut by parting the hair in the opposite direction of how it was cut is known as cross-checking. This method allows the stylist to visually assess the balance and evenness of the haircut from different angles. By doing so, they can identify any discrepancies in length or shape and make necessary adjustments to achieve a polished and accurate finish.

Sectioning refers to the practice of dividing the hair into manageable sections for cutting or styling, while blending involves seamlessly integrating different lengths or textures in a haircut. Layering is a cutting technique that creates varying lengths within the hair to add volume or shape. Although these techniques are essential for achieving different styles, they do not provide the same check for precision that cross-checking does.
