CT Barber key terms

Using a chemical product to destroy most harmful microorganisms on nonporous tools and surfaces. It does not kill bacterial spores, and it works only when the tool is cleaned first and the product is used exactly as labeled.

The complete destruction of all microorganisms, including bacterial spores, on an implement. It is required for tools that contact blood or cut the skin and is usually done in an autoclave after cleaning.

Routine cleaning that removes visible soil and reduces germs, such as washing hands, changing linens, and scrubbing surfaces with soap and water. It comes before disinfection and by itself does not kill pathogens.

A disinfectant carrying an Environmental Protection Agency registration number, which shows it has been tested and approved to kill listed pathogens when used according to the label directions.

Disease-causing organisms such as hepatitis B and HIV that spread through contact with blood or other body fluids. Barbers prevent exposure with gloves, barriers, and careful handling of sharp or contaminated items.

Treating every client's blood, body fluids, and used sharp items as if they carry infection, no matter what you believe about the person. Gloves and barriers are used every time.

A sheet supplied with each chemical product that lists its hazards, first aid, safe handling, and storage. It must be kept in the shop where workers can find it quickly in an emergency.

The angle at which hair is lifted away from the head before cutting. Low elevation keeps weight and length at the perimeter, while high elevation creates layers and removes weight.

A haircut in which the hair is held at zero elevation and cut straight across, producing a solid one-length edge. Also called a one-length cut.

The first strand or section cut in a haircut. Its length and angle become the reference that every later section is matched to so the finished shape is even.

A cutting technique where the clipper rides along the top of a comb held against the head, removing bulk and blending shorter lengths on the sides and nape.

A haircut in which hair gets gradually shorter toward the neckline and sideburns but still leaves a visible band of short hair rather than going down to bare skin.

A texturizing method where the shear tips cut into the ends of a section at an angle, softening a hard line and reducing bulk without shortening the overall length.

A shaving tool with a single exposed blade that folds into a handle. It must be stropped and honed, held at a shallow angle, and moved with light, controlled strokes.

A straight-razor stroke in which the blade travels across the skin while the barber's free hand does not pull the skin ahead of the blade.

Shaving in the direction opposite to hair growth. It gives a closer shave but raises the risk of razor burn, nicks, and ingrown hairs, so many clients are shaved with the grain first.

A product such as an alum block or styptic pencil applied to a small nick to stop minor bleeding during or after a shave.

Razor bumps caused when cut or curly hairs grow back into the skin and inflame it. It is common in clients with tightly curled beards and is managed by shaving with the grain and avoiding very close shaves.

A small amount of a chemical product applied to the skin and left for a day or two before the service to check whether the client is allergic to it.

Testing a small section of the client's hair with the product before a color, lightener, or perm service to see how the hair responds and how long the process needs.

A hydrogen peroxide solution mixed with permanent color or lightener. Its strength controls how much natural pigment is lifted and how much color is deposited.

A strong alkaline product that straightens curly or tightly coiled hair by breaking its internal bonds. It must be kept off already relaxed hair and rinsed out completely.

The product applied after a relaxer or perm that stops the chemical action, rebuilds the hair's bonds, and returns the hair to its normal pH.

Leaving a chemical product on too long or applying it to hair that is already chemically treated, which causes breakage, dryness, and excessive lightening or straightening.

Checking the client's hair and scalp for texture, porosity, elasticity, and condition, and looking for signs of scalp disorders, before deciding which services are safe.

How easily hair takes in and holds moisture, which depends on the condition of the cuticle. Highly porous hair absorbs products quickly and can also lose them quickly.

How far a wet strand of hair stretches before it breaks and whether it springs back. Poor elasticity means the hair is weak and may not survive chemical services.

A contagious fungal infection of the scalp that causes scaly patches and broken hairs. Barbers must not service it and should refer the client to a physician.

A condition that makes a service unsafe to perform, such as an open sore, a contagious scalp infection, or a recent allergic reaction. The service waits until the condition is resolved or cleared.

A conversation before the service in which the barber asks about the client's goals, hair history, and routine, explains realistic options, and agrees on a plan.

The client's clear agreement to a service after being told what it involves, the possible risks, and the alternatives. It protects both the client and the barber.

A private record of each client's services, formulas, products, and any reactions, kept so results can be repeated and problems avoided at the next visit.

Paying full attention to the client, asking clarifying questions, and repeating back what you understood so nothing is missed and the client feels heard.

Keeping a client's personal, health, and service information private and sharing it only when needed for their care or when the law requires it.

A credential issued by the state that allows a person to practice barbering. Working without one, or allowing an unlicensed person to serve clients, violates state rules.

A license that allows a barbershop to operate at a specific address under state sanitation and safety rules. It must be current and available for inspection.

A supervised training period in a licensed shop, where an apprentice learns barbering under a licensed barber for the number of hours the state requires before licensure.

The list of services a licensed barber may legally perform. Doing work outside that list, or beyond your training, can lead to discipline and endangers clients.

The Connecticut state agency that licenses barbers and barbershops, inspects shops, and enforces the barbering statutes and regulations.

An official visit by a state inspector who checks that a shop's tools, linens, chemicals, licenses, and cleaning practices meet the barbering regulations.
