Most of what makes a great haircut a great haircut happens underneath the surface. Precision layering is the unseen architecture — and it's the technique that separates a craftsman from a clipper-and-fade technician.
It controls weight
Layering removes weight without removing length. The surface looks the same; the cut sits completely differently.
It controls movement
Layered hair moves naturally. Blunt-cut hair sits in a single shape. For modern textured cuts, movement is the whole point.
It controls grow-out
A precisely layered cut grows out without losing shape. A blunt cut needs the chair every three weeks.
