Haircutting, Shaping, and Styling
The Geometry of a Cut
Every haircut is controlled by four variables: sectioning, distribution, elevation, and tension. Distribution is the direction hair is combed relative to its natural fall - natural fall, shifted, or overdirection. Elevation (projection) is the angle at which hair is held away from the head, and it determines the shape: 0 degrees builds a one-length or blunt line, 45 degrees graduates weight toward the perimeter, 90 degrees creates uniform layers, and 180 degrees produces long, blended layers. Tension must stay consistent, especially on curly or coarse hair, or the finished shape will be uneven.
Guides and Tools
A stationary guide is a fixed section that all later sections follow; a traveling guide moves with each cut section and is used for layered and clipper work. Cross-checking - combing the finished cut in the opposite direction - reveals missed strands and uneven lines. Shears cut clean lines; razors soften and texturize; clippers with guards create fades and tapers; point cutting, notching, and slide cutting reduce bulk without shortening the perimeter.
Styling
Blow-drying follows the cut: round brushes for volume and bend, paddle brushes for smoothness, and directional airflow to close the cuticle. Thermal tools require heat protection and correct barrel size - the smaller the barrel, the tighter the curl. Roller sets and pin curls rely on tension and cool-down to set the shape.
Traps and Rule of Thumb
Questions swap elevation with distribution, or claim that a blunt cut creates layers. Remember: elevation controls layering, distribution controls direction and weight, tension controls precision. If a stem asks what creates graduation, the answer is elevation above 0 with slight overdirection.
