- Sterilization
- A process that destroys all microorganisms, including bacterial spores, on an object; used for items that penetrate skin or contact blood.
- Disinfection
- The use of an EPA-registered chemical to kill most pathogenic organisms on nonporous surfaces and tools; does not necessarily kill spores.
- Sanitation
- The lowest level of decontamination: washing with soap and water to reduce visible soil and contaminants to a safe level before disinfection.
- Bloodborne pathogens
- Disease-causing microorganisms carried in blood or body fluids, such as hepatitis B and HIV; require gloves and an exposure-control plan.
- Anagen phase
- The active growth phase of a hair follicle, lasting roughly two to seven years; about 80–90% of scalp hairs are in this phase.
- Catagen phase
- A short transitional phase of about two to three weeks when hair growth stops and the follicle begins to shrink.
- Telogen phase
- The resting phase of the hair cycle, lasting about three months, ending when the club hair is shed and a new anagen hair begins.
- Hair porosity
- The ability of hair to absorb moisture, classified as low (cuticle tight), normal, or high (cuticle damaged); high porosity absorbs and loses moisture quickly.
- Hair density
- The number of hairs per square inch on the scalp, described as thin, medium, or thick; it affects cutting and styling decisions.
- Hair texture
- The diameter of an individual hair strand, described as fine, medium, or coarse; fine hair is more fragile and processes faster.
- Epidermis
- The outermost, protective layer of skin; it contains no blood vessels and is the barrier that shaving and products contact first.
- Dermis
- The middle skin layer containing nerves, blood vessels, glands, and hair follicles; a cut into it bleeds and needs first aid.
- Subcutaneous layer
- The deepest skin layer of fat and connective tissue that insulates the body and anchors the skin to underlying structures.
- Oval face shape
- A balanced face shape with slightly wider cheekbones and a gently tapering jaw; most hairstyles and beard lines suit it.
- Round face shape
- A face with similar width and length and full cheeks; styles that add height and reduce side width create balance.
- Square face shape
- A face with a strong, angular jaw and broad forehead; soft, rounded lines and texture reduce the angularity.
- Heart face shape
- A face wider at the forehead and cheekbones with a narrow chin; volume at the jawline and a soft fringe balance it.
- Diamond face shape
- A face with a narrow forehead and chin and wide cheekbones; volume at the forehead and jaw softens the cheek width.
- Oblong face shape
- A longer-than-wide face with a narrow width; styles that add width at the sides and avoid added height create balance.
- Triangle face shape
- A face with a narrow forehead and a wide jaw; volume at the top and a lighter jawline balance the lower width.
- Shaving with the grain
- Moving the razor in the direction of hair growth; it reduces irritation and razor burn and is the first pass for sensitive skin.
- Razor angle
- The angle between the razor blade and the skin, commonly about 30 degrees; too steep or too much pressure causes nicks and burn.
- Shaving lather
- Soap or cream worked into a foam that lifts hair, holds moisture against the skin, and provides glide for the razor.
- Neckline placement
- The beard line on the neck, typically set about one finger above the Adam's apple and shaped in a gentle curve.
- Cheek line
- The upper boundary of a beard on the cheek, usually following the natural growth pattern and kept symmetrical on both sides.
- Taper cut
- A haircut where length gradually shortens from one area to another, often from the sideburn to the nape, without a visible line.
- Fade
- A taper that blends short hair into skin or near-skin length, classified as low, mid, or high by where the transition starts.
- Clipper-over-comb
- A cutting technique where clippers run over a comb to remove length while the comb lifts and controls the hair.
- Scissor-over-comb
- A blending technique using shears over a comb to remove bulk and create soft transitions, common in longer men's styles.
- Cross-checking
- Cutting or checking the hair from a second, perpendicular direction to find and correct uneven lengths and blend lines.
- Patch test
- A small skin test of a product, such as color or a chemical, applied before full use to check for an allergic reaction.
- Towel barbering
- The hot-towel service step that softens the beard and opens pores before shaving; the towel is applied warm, not scalding.
