Define ‘graduation’ in haircutting terminology.

Graduation in haircutting terminology refers to a technique where the hair length gradually increases from the nape to the crown. This process involves cutting the hair in such a way that the shorter layers at the base are blended with longer layers towards the top, resulting in a soft, layered appearance. This technique can add volume and shape to a hairstyle, creating a natural, flowing look.

The essence of graduation is in its graduated length, which allows for movement and is often used to enhance the overall silhouette of a haircut. It’s particularly effective for styles that require a bit of elevation and height at the crown, making the hair appear more dynamic.
