3.3 Haircutting

Haircutting on the exam is tested as applied geometry: where you hold the hair and at what angle determines the shape. Master the vocabulary of reference points, elevation, and guidelines, and the cut questions become predictable.

Reference Points of the Head

Reference points are spots on the head that mark where the surface changes, so cuts stay symmetrical. Key points:

• Parietal ridge — the widest part of the head (the "crest"); also called the hatband.
• Occipital bone — the bone that protrudes at the back base of the skull.
• Apex — the highest point on top of the head.
• Four corners — locate the top by connecting the two front and two back corners.
• Nape — the back of the neck below the occipital.

Sections and Partings

The head is divided into manageable sections before cutting. A parting is the line that separates the hair within a section. Subdividing into uniform partings keeps tension and length even. Tension that is too tight on wet, elastic hair makes the cut shorter than intended once it dries — a frequently tested cause of an uneven cut.

Elevation, Angles, and the Guideline

Elevation (also called projection) is the angle at which the hair is held away from the head before cutting. It controls how much weight stays in the cut:

A guideline (guide) is the section of previously cut hair that determines the length of the next section. Two kinds:

• Stationary guideline — does not move; each new section is brought to it (used for blunt cuts and to build weight/graduation).
• Traveling (mobile) guideline — moves with each parting (used for layered and uniform cuts).

The cutting line is the angle at which the fingers and shears actually cut across the section (horizontal, vertical, or diagonal). Over-direction — combing hair past its natural fall to one point — increases length gradually and is how long layers and increased length are built.

Worked example: a client wants a classic chin-length bob with a heavy, solid perimeter. You cut at 0 degrees elevation with a stationary guideline at the nape, bringing each section down to that guide — that is a blunt cut. If she instead wants soft layers all over with no weight line, you elevate every section to 90 degrees using a traveling guideline for a uniform-layered cut.

Tools and Safety

Know the cutting tools and their use:

• Shears (scissors) — primary blunt and slide cutting; sizes 4.5"–5.5" are common.
• Texturizing/thinning shears — remove bulk without removing length.
• Razor — softer, tapered ends; used only on wet hair to avoid tearing.
• Clippers — close cutting, tapers, and fades; guards set the length.

Safety rules the exam emphasizes:

• Palm the shears (rotate them into your palm) and the comb while combing or while your free hand works.
• Engage the safety guard or close the razor when not actively cutting.
• Never point or cut toward the client's skin, ears, or your own fingers.
• Disinfect metal tools in an EPA-registered hospital-grade disinfectant between clients per TDLR sanitation rules, and discard single-use razor blades in a sharps container.

A common trap: a question states the stylist used a razor on dry hair — that is incorrect technique because dry razor cutting tears the cuticle and causes split ends.

Tension, Distribution, and Cross-Checking

Three more terms round out the cutting questions. Tension is the amount of pull on the hair while cutting; firm even tension gives a clean precise line, but excessive tension on wet, elastic, or curly hair makes the finished cut shorter than the client wanted once it dries and springs up. Distribution is the direction the hair is combed relative to its parting before the cut: natural, perpendicular, or directional (over-direction).

Cross-checking means parting the haircut in the opposite direction from how it was cut (horizontal sections checked vertically and the reverse) to confirm the lengths are even and the line is balanced before the client leaves the chair.

Body position and ergonomics are tested as both safety and professionalism: keep your weight evenly balanced, position the client's head straight because tilting the head changes the perimeter line, and lower the chair or your stance rather than hunching. Texas sanitation rules require that combs, shears, and clipper guards be cleaned and immersed in an EPA-registered disinfectant between every client, and that any blood exposure from a nick triggers the salon's exposure-control procedure with single-use blades discarded in a sharps container.

Knowing both the geometry and these handling rules covers the haircutting questions on the operator exam, which test the elevation that produces each basic shape, the role of stationary versus traveling guidelines, the effect of tension and over-direction, and the safe handling and disinfection of shears, razors, and clippers between clients.
