32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Sanitize vs. Sterilize
- Sanitizing reduces pathogens on surfaces to safe public health levels, while sterilizing destroys all microbial life, including bacterial spores, usually through heat or chemical sterilants.
- EPA-registered disinfectant
- A product approved by the Environmental Protection Agency for killing pathogens on hard surfaces; barbers must use hospital-grade, tuberculocidal products for blood contact.
- OSHA Bloodborne Pathogens
- Federal standard requiring gloves, sharps disposal, an exposure control plan, and Hepatitis B vaccination for workers with potential blood exposure.
- Hand washing steps
- Wet hands, apply soap, scrub for at least 20 seconds including between fingers and under nails, rinse thoroughly, and dry with a single-use towel.
- Hair shaft layers
- The cuticle is the outer protective layer, the cortex contains melanin and disulfide bonds, and the medulla is the central core that may be absent in fine hair.
- Anagen growth phase
- The active growth phase of the hair cycle, lasting two to six years, during which the follicle produces new hair cells.
- Hair porosity test
- A strand that floats indicates low porosity, while one that sinks quickly indicates high porosity, guiding product choice and chemical processing time.
- Elasticity test
- A wet strand is stretched; normal hair returns to shape, while hair that snaps indicates damage and contraindicates chemical services.
- Elevation in haircutting
- The angle at which hair is held from the head; zero degrees creates a blunt line, 45 degrees graduates, and 90 degrees layers.
- Stationary guide
- A subsection of hair that does not move and serves as the length reference for all subsequent sections in a haircut.
- Clipper guard sizes
- Standard guards correspond to #1 at 1/8 inch, #2 at 1/4 inch, #3 at 3/8 inch, and #4 at 1/2 inch of remaining hair.
- Texturizing techniques
- Point cutting, notching, and slicing remove bulk and soften lines, and are performed after the main shape is established.
- Shaving grain direction
- Shave with the grain first to reduce irritation, across the grain second, and against the grain only for tolerant skin.
- Razor angle
- The blade is held at approximately 30 degrees to the skin, using short strokes with light pressure and rinsing between strokes.
- Shaving contraindications
- Moles, warts, inflamed acne, and broken skin must not be shaved; these conditions require referral rather than service.
- Hot towel purpose
- A warm, moist towel softens hair and opens pores before shaving, while a cool towel afterward closes pores and soothes skin.
- pH and hair
- Hair is naturally acidic at about pH 4.5 to 5.5; alkaline products swell the cuticle, while acidic products smooth and close it.
- Permanent wave chemistry
- A reducing agent breaks disulfide bonds in the cortex, and a neutralizer reforms them into the new curl pattern.
- Developer volumes
- Ten volume deposits tone, 20 volume lifts one to two levels, 30 volume lifts two to three, and 40 volume lifts three to four.
- Patch test
- A small application of product on skin before a color or relaxer service to detect allergic reaction; results are read per manufacturer directions.
- Skin layers
- The epidermis is the outer protective layer, the dermis contains nerves and glands, and the subcutaneous layer provides fat and insulation.
- Hair follicle structures
- The bulb contains the matrix, the papilla supplies blood, the sebaceous gland produces oil, and the arrector pili muscle causes goose bumps.
- Nail structures
- The nail plate covers the nail bed, the matrix produces growth, the lunula is the white half-moon, and the cuticle is the eponychium.
- Facial bones
- The mandible is the only movable facial bone; the skull also includes frontal, parietal, temporal, and occipital bones.
- Skin types
- Normal, dry, oily, combination, and sensitive skin types are identified before selecting products or performing facial services.
- Facial massage movements
- Effleurage, petrissage, tapotement, and vibration are applied upward and outward, avoiding pressure on arteries and sensitive areas.
- Facial contraindications
- Open lesions, active acne, sunburn, recent cosmetic procedures, and contagious conditions prohibit facial services and require referral.
- Nail filing direction
- Files should move in one direction along the free edge to prevent splitting and peeling of the nail plate.
- Nevada licensing board
- The Nevada State Board of Cosmetology and Barbering regulates barber licensing, shop permits, and sanitation standards in the state.
- Barber license requirements
- Nevada requires completion of an approved program, typically 1,500 hours, plus passing written and practical examinations for licensure.
- Shop sanitation rules
- Licenses must be posted visibly, implements stored in clean covered containers, and single-use items discarded after each client.
- Blood exposure protocol
- Stop the service, put on gloves, clean the wound, disinfect the area, and dispose of contaminated items according to OSHA standards.
