Graduation
A cutting method that stacks shorter hair underneath longer hair, building weight and shape.
Also: graduated cut, stacking
Graduation is a cut where the hair underneath is shorter than the hair on top, so the ends stack on each other and build weight at one level. It is made by lifting the hair at a low or medium angle, often about 45 degrees. The graduated bob, short and stacked at the nape and longer at the front, is the best-known example. Graduation gives roundness at the back of the head and is also used in men's classic cuts.
