5.2 Haircutting tools & techniques

Choosing and controlling haircutting tools

The stylist selects an implement based on the effect wanted, the hair's texture, and the finish required. The NIC theory exam expects you to know each tool's purpose, how it is held, and how it is kept safe and sanitary under North Carolina Board rules.

Shears (scissors)

Haircutting shears are the primary tool for cutting blunt, precise lines and are commonly 5 to 5.5 inches long. The stylist places the thumb in the smaller movable ring and the ring finger in the larger still ring, with the little finger resting on the brace (tang) and the index finger along the shank. Only the thumb moves; the still blade stays stable so the line stays clean.

Palming the shears: while combing or holding a section, the stylist removes the thumb and palms the shears — closing them into the palm — so the points are never aimed at the client. Palming protects the client, keeps control of the comb, and keeps both tools ready. Combing is done with the shears palmed at all times.

Thinning and texturizing shears

Texturizing shears (also called thinning, tapering, or notching shears) have one straight blade and one notched, toothed blade. They remove bulk and blend without shortening the overall length, softening weight lines. The number and spacing of the teeth control how much hair is removed with each pass.

Razor

A razor, fitted with a guard for safety, cuts a softer, more tapered, wispy end because it slices each strand at an angle rather than straight across. Razors are used on wet hair only; cutting dry hair with a razor pulls and damages it. The guard controls how much hair is removed and shields the stylist and client from the blade.

Clippers, trimmers, and guards

Clippers cut hair very close to the scalp and are used for clipper-over-comb work, fades, and men's cutting. Detachable or adjustable guards (attachment combs) set the cutting length. Trimmers, also called edgers or outliners, are smaller clippers used to create crisp outlines, clean necklines, edge around the ears, and detail facial hair.

Combs

Different combs serve different tasks:

Holding, positioning, and tension

The comb and shears work as a pair. The stylist combs a subsection smooth, transfers the comb to the holding hand, palms the shears, and only then cuts, so the section is clean and evenly distributed before the blade closes. Cutting can be done with the palm facing up or down and either inside or outside the knuckles; cutting inside the knuckles (fingers toward the stylist) is common for interior sections, while cutting outside the knuckles keeps the guide visible on perimeter lines.

Tension is the amount of pull placed on a subsection while cutting. Even, moderate tension produces an even line, and maximum tension is reserved for straight hair where precision is needed. Tension is reduced on curly hair and around the ears, hairline, and nape, where too much pull makes the hair spring up shorter than intended once released. Body position matters too: the stylist stands squarely in front of the section being cut and keeps the client's head upright so the natural fall — and therefore the finished length — is judged correctly.

Texturizing techniques

Once the shape is established, texturizing removes weight or adds movement and separation:

• Point cutting (pointing): the shear tips are directed into the ends of the hair to soften them and remove length weight, leaving a broken, textured edge.
• Slide cutting (slithering / effilating): the partially opened shears are slid down the strand from a higher to a lower point, tapering and removing length gradually without leaving a blunt line.
• Notching: a more aggressive form of point cutting in which larger V-shaped pieces are removed from the ends for a chunky, textured look.
• Slithering: running the partly open shears along the strand to reduce bulk — the shear-based equivalent of thinning.

Clipper-over-comb and shear-over-comb

In clipper-over-comb and shear-over-comb work, the comb replaces the fingers as the holding tool. The comb lifts and holds the hair at the desired angle while the clipper or shear cuts along the comb's teeth. Moving the comb up and out from the scalp while cutting progressively creates a tapered, graduated blend — essential for tight necklines, short tapers, and men's cuts where fingers cannot hold hair close enough to the head.

Safety and sanitation

All cutting implements are cleaned and disinfected between clients with an EPA-registered, hospital-grade disinfectant, and anything that contacts broken skin or blood is discarded or fully disinfected under North Carolina Board rules. Shears and razors are kept sharp because dull blades tear and slip. Blades point away from the client when not cutting, and razors are palmed and guarded when set down.
