- Disinfection
- Related: Sterilization, EPA-Registered Disinfectant, Bloodborne Pathogens
The process of killing or reducing harmful microorganisms on tools and surfaces using an EPA-registered product, short of destroying all bacterial spores. It is the standard level of protection required for most barber implements between clients.
- Sterilization
- Related: Disinfection, Autoclave
A process that destroys all microbial life, including bacterial spores, usually through steam under pressure in an autoclave or by dry heat. It is required for implements that may contact blood or penetrate the skin.
- EPA-Registered Disinfectant
- Related: Disinfection, Contact Time
A product carrying an Environmental Protection Agency registration number and label claims for killing specific organisms on hard, nonporous surfaces. The label directions for contact time and dilution must be followed exactly to be effective.
- Contact Time
- Related: EPA-Registered Disinfectant, Disinfection
The length of time an implement must stay fully submerged or wet with a disinfectant for the product to work as labeled. Cutting this time short means the tool is not properly disinfected.
- Bloodborne Pathogens
- Related: Standard Precautions, Sharps Container, Exposure Incident
Disease-causing microorganisms carried in blood or body fluids, such as hepatitis B, hepatitis C, and HIV. Barbers must follow standard precautions and OSHA rules to prevent exposure from clients and contaminated tools.
- Standard Precautions
- Related: Bloodborne Pathogens, Exposure Incident
An approach in which all blood and certain body fluids are treated as potentially infectious regardless of the client's known health status. It includes gloves, handwashing, and proper handling of contaminated items.
- Exposure Incident
- Related: Bloodborne Pathogens, Standard Precautions
A specific event in which a barber's skin, eyes, or mucous membranes contact blood or other potentially infectious material, such as a nick from a razor. The incident must be reported and documented per the shop's exposure control plan.
- Sharps Container
- Related: Bloodborne Pathogens
A rigid, puncture-resistant, leakproof container with a biohazard label used to discard used razor blades and other sharp items. It must not be overfilled and is never used for general trash.
- Autoclave
- Related: Sterilization
A device that sterilizes tools using high-pressure steam at elevated temperature. Items must be cleaned first and properly packaged or placed per the manufacturer's instructions to achieve sterilization.
- Porous vs. Nonporous Implements
- Related: Disinfection, Single-Use Item
Nonporous items such as metal shears, combs, and clipper blades can be disinfected or sterilized. Porous items like cloth towels, neck strips, and wooden handles cannot be reliably disinfected and should be single-use or laundered.
- Single-Use Item
- Related: Porous vs. Nonporous Implements
A product designed to be used on one client and then discarded, such as a straight razor blade, wooden manicure stick, or neck strip. It is never cleaned and reused.
- Tinea Capitis
- Related: Contraindication, Pediculosis
A contagious fungal infection of the scalp and hair shafts, often seen as scaly patches and broken hairs. It is a contraindication to chemical and certain styling services and requires medical referral.
- Pediculosis
- Related: Tinea Capitis, Contraindication
An infestation of lice on the scalp or hair. It is highly contagious, so service must be refused and the client referred for treatment; tools and linens require special handling.
- Contraindication
- Related: Tinea Capitis, Patch Test
A condition or circumstance that makes a service unsafe or inadvisable for a client. Examples include open sores, infectious scalp disease, or a history of allergic reaction to a product.
- Patch Test
- Related: Contraindication, Developer
A small amount of a chemical product applied to the skin to check for an allergic reaction before a full service. Results are read after a set waiting period, and a positive reaction means the product must not be used.
- Hair Porosity
- Related: Cuticle Layer, Strand Test
The hair's ability to absorb and hold moisture, related to how tightly the cuticle layers lie. Highly porous hair absorbs chemicals quickly and may process faster, while low-porosity hair resists absorption.
- Strand Test
- Related: Hair Porosity, Processing Time
A test performed on a small section of hair before a chemical service to predict how the hair will respond to a product. It helps determine processing time, strength, and whether the service is safe to perform.
- Cuticle Layer
- Related: Hair Porosity, Cortex
The outermost layer of the hair shaft, made of overlapping scale-like cells that protect the inner layers. Its condition determines shine, porosity, and how chemicals penetrate the hair.
- Cortex
- Related: Cuticle Layer, Medulla
The middle and thickest layer of the hair shaft, containing the pigment granules and most of the hair's strength and elasticity. Chemical services change the hair by acting on the cortex.
- Medulla
- Related: Cortex
The innermost, usually hollow core of the hair shaft, which may be absent in fine hair. It contributes little to the hair's strength or appearance.
- Growth Pattern
- Related: Elevation
The direction in which hair grows from the scalp, including whorls and cowlicks. It affects how hair falls and must be considered when cutting and styling to avoid gaps or uneven lengths.
- Elevation
- Related: Graduation, Growth Pattern
The angle at which hair is held away from the head while cutting. Lower elevation builds weight and length; higher elevation removes weight and creates layers and graduation.
- Graduation
- Related: Elevation
A cutting technique where hair lengths build from shorter at the perimeter to longer toward the interior, creating a stacked or wedge effect. It is controlled by elevation and sectioning.
- Guideline
- Related: Elevation
The first cut section of hair that establishes the length and shape the remaining hair follows. A missing or incorrect guideline causes an uneven haircut.
- Razor Cutting
- Related: Stropping, Honing
Cutting or texturing hair with a straight razor or razor comb to create soft, tapered ends and blended texture. It requires a sharp blade and controlled angle to avoid removing too much hair.
- Honing
- Related: Stropping, Razor Cutting
The process of grinding and sharpening a straight razor blade on a stone to restore a cutting edge. It is followed by stropping to polish and align the edge.
- Stropping
- Related: Honing
The process of polishing and straightening a straight razor's edge by drawing it across a leather strop. It is done before shaving to make the blade glide smoothly and cut cleanly.
- Shaving Lather
- Related: Shaving Angle
A mixture of shaving soap or cream and water whipped to a creamy consistency that softens the beard and protects the skin. Proper lather reduces friction and irritation during shaving.
- Shaving Angle
- Related: Shaving Lather
The angle at which the razor blade meets the skin, generally kept low to shave close without scraping. The wrong angle causes razor burn, nicks, or an incomplete shave.
- Ingrown Hair
- Related: Shaving Angle
A hair that curls back into the skin or grows sideways, causing inflammation and sometimes infection. Close shaving and improper technique can contribute, and clients should be advised on prevention.
- Beard Grain
- Related: Shaving Angle, Ingrown Hair
The natural direction in which facial hair grows. Trimming and shaving with the grain reduces irritation, and mapping the grain is essential for an even beard line.
- Developer
- Related: Patch Test, Processing Time
A hydrogen peroxide solution that, when mixed with hair color or lightener, supplies the oxygen needed to develop color and lift pigment. Its strength, stated in volume, controls the amount of lift.
- Processing Time
