Clipper-over-comb

A cutting technique where clippers run over a comb held against the head to remove bulk and blend lengths. The comb controls how much hair the blade reaches, making it useful for short tapered areas.

Related: Fade, Taper, Guard
Fade

A haircut in which length increases gradually from skin at the bottom to longer hair on top, with no visible lines. Blending quality depends on clipper control, guard changes, and consistent sectioning.

Related: Clipper-over-comb, Taper, Guard
Taper

A gradual shortening of hair at the neckline and sideburns while leaving length above. It is a softer, longer alternative to a full fade and is blended with clippers, comb, or shears.

Related: Fade, Clipper-over-comb, Neck strip
Guard

A plastic attachment fitted over clipper blades to control the length of hair left behind. Guards are numbered by the length they cut and must be cleaned and disinfected between clients.

Related: Fade, Clipper-over-comb
Elevation

The angle at which hair is held away from the head before cutting. Low elevation builds weight and length; high elevation removes weight and creates layers and graduation.

Related: Graduation, Sectioning
Graduation

A cutting effect where lengths stack or build up in a specific area, usually created by cutting at an angle with tension. It adds volume and shape, and is common in classic men's tapered cuts.

Related: Elevation, Sectioning
Sectioning

Dividing hair into controlled, clipped-off areas before cutting so each part is worked in order. Clean sectioning keeps the cut balanced and prevents missed or overcut areas.

Related: Elevation, Graduation
Neck strip

The final cleanup along the hairline at the nape, done with clippers, trimmer, or razor after the main cut. It defines the outline and must be executed with clean, disinfected tools.

Related: Taper, Razor shave
Razor shave

Removing facial hair with a straight razor and lather, working with the grain first and across or against it only with care. The razor is held at a shallow angle and the skin kept taut.

Related: Lather, Shaving stroke, Neck strip
Lather

The foam built from shaving soap or cream and water that cushions the skin and holds moisture during a shave. It is applied in a thin, even layer and worked into the beard to soften hair.

Related: Razor shave, Shaving stroke
Shaving stroke

The direction and pressure of a razor pass over the skin. Short, light strokes with the grain reduce irritation, while stretching the skin and using too much pressure cause nicks and razor burn.

Related: Razor shave, Lather, Razor burn
Razor burn

Irritation, redness, and stinging after shaving, often from too much pressure, a dull blade, or shaving against the grain. Cooling products and proper technique help prevent and soothe it.

Related: Shaving stroke, Razor shave
Beard trim
