NY Barber key terms

The angle at which hair is held away from the head before cutting. Holding hair at 90 degrees builds layered length; holding it flat against the scalp preserves weight and length.

The first cut strand or section that sets the length and shape all later sections follow. Also called a guide or base cut, it may be stationary or moving.

Dividing the head into controlled working areas, such as four quadrants or horizontal partings, so hair is cut evenly and no strand is missed.

A cut made with zero elevation so all hair ends fall on one line. It produces a solid, heavy perimeter and maximum weight at the ends.

Cutting with slight elevation so shorter layers sit above longer ones, creating stacked weight and volume near the perimeter or nape.

A gradual shortening of hair length toward the neckline, sideburns, or around the ears, blending longer top hair into tight edges.

A taper taken to the skin or near-skin at the perimeter, with clipper guard lengths blended upward so no hard lines remain visible.

A cutting method in which clippers run over a comb holding hair away from the scalp, removing bulk and blending short sides and nape areas.

A removable attachment fitted to clipper blades that controls how much hair is cut, labeled by number or millimeter length.

Cutting techniques such as point cutting, notching, or slicing that remove bulk and soften a shape without changing its overall length.

Using a straight razor or razor-edged tool to cut hair at an angle, producing soft, tapered ends and a slightly diffused finish.

Recutting a section from a different direction or elevation to confirm the shape is balanced and no stray lengths remain.

The natural direction hair grows from the scalp, such as a cowlick, whorl, or nape growth. Cutting against it can leave gaps or stubborn sections.

The direction in which hair flows from the scalp. Streams affect where weight falls and how a finished style lies.

A folding razor with a single exposed blade used for shaving and outlining. The blade must be changed or stropped and never shared without disinfection.

A leather or canvas strip used to align and polish a straight razor edge before shaving, extending blade life and improving comfort.

Grinding a straight razor blade on a sharpening stone to restore its bevel and cutting edge after wear or damage.

A whipped mixture of shaving soap or cream and water applied to soften beard hair, lubricate the skin, and hold hair upright for cutting.

Directional passes of the razor, generally with the grain first and across or against the grain only when skin tolerates it, to reduce irritation.

Redness and stinging after shaving caused by too much pressure, a dull blade, insufficient lather, or shaving against the grain on sensitive skin.

A hair that curls back into the skin or grows sideways after shaving, causing a bump. Avoid close shaving over it and advise the client not to pick.

Shaping facial hair by establishing lines at the cheek, jaw, and neck, then tapering length so the finished beard suits face shape and growth.

The crisp boundary line cut along a beard, mustache, or hairline edge to define the shape and remove stray hairs.

Reducing mustache length and bulk with scissors or clippers, then defining the upper lip line while keeping the shape symmetrical.

Applying a warm, damp towel to the face before or after shaving to soften hair, open pores, and relax the client. Towels must be clean and sanitized between clients.

Destroying most harmful microorganisms on nonporous tools and surfaces using an EPA-registered product mixed and used according to its label.

Destroying all microbial life, including bacterial spores, usually through an autoclave. Required for items that contact broken skin or blood.

Reducing dirt and some microorganisms on surfaces and linens through washing and low-level cleaning, a lower standard than disinfection.

A disinfectant label claim showing it kills the bacterium that causes tuberculosis. New York requires hospital-grade, tuberculocidal products for tools and implements.

A number on a disinfectant label confirming the product is registered with the U.S. Environmental Protection Agency for its stated use.

A container of disinfecting solution in which combs and shears soak between clients. Solution must be changed per label directions and tested for strength.

The protocol for blood exposure: stop service, wear gloves, clean the area, remove contaminated material, disinfect with an EPA-registered product, and wash hands.

Treating all blood and body fluids as infectious regardless of the client, using gloves and barriers and disinfecting all contact items.

The skin, hair, nails, and glands that form the body's outer covering, protecting against injury and infection and helping regulate temperature.

The thin outer layer of skin with no blood vessels, made of cells that continually shed and renew from the base upward.

The thicker layer beneath the epidermis containing blood vessels, nerves, hair follicles, and glands. It supplies the epidermis with nutrients.

A tube-shaped pocket in the dermis from which hair grows. It anchors the hair root and connects to sebaceous glands and a tiny muscle.

A gland attached to the hair follicle that secretes sebum, an oil that lubricates hair and skin and helps retain moisture.

The repeating phases of hair growth, rest, and shedding. Cutting hair does not change the cycle, though health and hormones can.
