The standard measurement for hair cutting angles is expressed in degrees. When hairstylists cut hair, they often work with specific angles to achieve certain styles and shapes, which are crucial for creating layers, bobs, or other styles that depend on the direction and elevation of the cut. Using degrees allows for precise communication and replication of styles, ensuring consistency across different haircuts.

Measuring angles in inches, centimeters, or millimeters does not provide the necessary information about the angle at which the hair is cut. Instead, these measurements pertain to length rather than the degree of elevation or inclination used during the cutting process. Degrees offer a clear and universally understood method to define the angle, such as 45 degrees for a layered cut or 90 degrees for a straight, blunt cut. Thus, the use of degrees is essential in professional hair cutting to achieve the desired results effectively.
