32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Disinfection contact time
- The full immersion time stated on the EPA-registered disinfectant label, commonly 10 minutes, during which implements must stay submerged after cleaning to kill pathogens.
- Sterilization definition
- The complete destruction of all microbial life, including bacterial spores, usually achieved with an autoclave using steam under pressure for items that may contact blood.
- Sanitizing vs disinfecting
- Sanitizing removes visible debris with soap and water; disinfecting uses a hospital-grade chemical to kill pathogens on nonporous surfaces and tools.
- Blood spill response
- Don gloves, stop the service, absorb and clean visible blood, then disinfect the surface with a tuberculocidal disinfectant at label dilution and contact time.
- Sharps container rule
- Used razor blades and other sharp single-use items go into a labeled, puncture-resistant sharps container, never into ordinary trash or a towel.
- HBV surface survival
- Hepatitis B virus can remain infectious on dried surfaces and tools for at least seven days, which is why thorough disinfection after every client matters.
- OSHA exposure control plan
- A written Bloodborne Pathogens program covering PPE, HBV vaccination offered free to at-risk workers, spill procedures, and post-exposure medical evaluation.
- Hair shaft layers
- Cuticle is the outer protective scale layer, cortex is the bulk containing pigment and strength, and medulla is the central core that may be absent in fine hair.
- Hair growth phases
- Anagen is active growth lasting two to six years, catagen is a short transition of weeks, and telogen is a resting phase of about three months before shedding.
- Follicle shape and curl
- A round follicle produces straight hair, an oval follicle produces wavy hair, and a flat or elliptical follicle produces curly or kinky hair.
- Tinea capitis signs
- A contagious fungal scalp infection showing scaly circular patches and broken hairs; barbers must refuse service and refer the client to a physician.
- Pediculosis capitis
- Head lice infestation identified by nits glued to hair shafts near the scalp; service is contraindicated until the client has been treated.
- Furuncle vs carbuncle
- A furuncle is a localized bacterial follicle infection or boil; a carbuncle is a cluster of connected boils, and both contraindicate shaving over the area.
- Alopecia types
- Alopecia areata is patchy noncontagious autoimmune loss, alopecia totalis is loss of the whole scalp, and alopecia universalis is loss over the entire body.
- Hair protein and pH
- Hair is about ninety percent keratin, and the hair and scalp are acidic near pH 4.5 to 5.5, which guides shampoo and chemical service selection.
- Cutting elevation angles
- Zero degrees gives a blunt one-length line, 45 degrees gives graduation, 90 degrees gives uniform layers, and 180 degrees gives long layers.
- Stationary vs traveling guide
- A stationary guide is the first cut section held as the fixed length reference; a traveling guide moves the previous section forward as the new reference.
- Cross-checking a haircut
- Cutting or combing the hair in the opposite direction from the original section pattern to reveal uneven lines before finishing the service.
- Tapering sequence
- Start at the nape or sideburn with the longest guard and work toward the tightest area, rocking the clipper out to blend the transition line.
- Straight razor angle
- Hold the razor at roughly 30 degrees to the skin, stretch the skin taut, and use short strokes to shave closely without nicks.
- Shaving grain direction
- Shave with the grain first, re-lather, then shave across or against the grain only if the client's skin tolerates it without irritation.
- Razor cut response
- A slice rather than a nick: apply pressure with clean gauze, disinfect the razor before continuing, and document the incident if required.
- Developer volumes
- Ten volume equals three percent, twenty volume equals six percent, thirty volume equals nine percent, and forty volume equals twelve percent hydrogen peroxide.
- Permanent color action
- Permanent color lifts and deposits pigment through an oxidation reaction with hydrogen peroxide developer, opening the cuticle and forming pigment inside it.
- Color mixing ratio
- A one-to-one ratio uses equal parts color and developer; a one-to-two ratio uses twice as much developer as color, changing lift and processing time.
- Patch and strand tests
- A patch test checks allergy 24 to 48 hours before service; a strand test predicts processing time and final color on a small hair section.
- Relaxer chemistry
- Hydroxide or ammonium thioglycolate relaxers break disulfide bonds to straighten hair; the neutralizer reforms the bonds and stops the chemical process.
- No double processing rule
- Never apply relaxer over previously relaxed hair or over an irritated scalp; base the scalp and keep product off already processed lengths.
- Perm wrapping process
- Hair is wrapped wet on rods with reducing lotion, processed, rinsed thoroughly, then neutralized; a test curl shows when the wave is fully formed.
- Chemical service drape
- Cape, towel, gloves, and ventilation protect the client and barber during color, lightener, and relaxer services; eyes rinse with water for 15 minutes.
- License renewal requirement
- State barber boards set continuing education hours for renewal, and the current license must be posted at the workstation during practice.
- Client record card
- A confidential record of service dates, formulations, patch and strand test results, and adverse reactions used to repeat or adjust future services.
