- California barber training hours
- California requires 1,500 clock hours of approved barber training before a candidate may take the licensing exam; other states set different hour requirements.
- Barber license renewal
- A barber license expires on the date set by the state board and must be renewed with the required fee; practicing on an expired license is a violation.
- Scope of practice
- The specific services a licensed barber may legally perform for pay, such as cutting, shaving, and chemical services; working outside it is illegal.
- State board authority
- The state barbering board writes licensing and sanitation rules, issues licenses, inspects shops, and may fine, suspend, or revoke a license for violations.
- Hospital-grade disinfectant
- An EPA-registered product labeled bactericidal, virucidal, and fungicidal, used at the dilution and contact time stated on its label to disinfect implements and surfaces.
- Disinfection versus sterilization
- Disinfection destroys most pathogenic organisms on surfaces but not bacterial spores; sterilization in an autoclave destroys all microorganisms, including spores.
- Blood spill procedure
- Stop the service, put on gloves, clean the area with soap and water, apply an EPA-registered hospital disinfectant, and seal contaminated waste in a bag.
- Pediculosis capitis
- Head lice infestation is highly contagious; the barber refuses service, disinfects all implements, and refers the client for treatment before any hair service.
- Single-use neck strip
- A disposable paper strip placed between the cape and the client's skin so the cape never contacts skin and cannot transfer soil or organisms between clients.
- Blunt haircut
- Cutting at zero elevation with hair held at its natural fall creates a solid one-length line and keeps the greatest weight at the perimeter.
- Elevation in haircutting
- The angle at which hair is held away from the head: 0 degrees is blunt, 45 degrees is graduation, 90 degrees is uniform layers, 180 degrees is long layers.
- Tension in haircutting
- The amount of pull applied to a section of hair; greater tension removes more length, so uneven tension produces an uneven finished cut.
- Clipper guard numbers
- Guards are numbered by the length of hair they leave; lower numbers cut closer to the scalp and higher numbers leave longer hair.
- Guide in a haircut
- The first section of hair cut, which establishes the length and shape against which every remaining section is measured.
- Shaving with the grain
- Moving the razor in the direction the hair grows, which reduces irritation and razor bumps, especially on clients with tightly curled facial hair.
- Honing versus stropping
- Honing grinds and sharpens a straight razor edge on a stone; stropping on leather smooths and realigns that edge before the shave.
- Pseudofolliculitis barbae
- Razor bumps formed when tightly curled hair grows back into the skin and inflames it; managed by shaving with the grain or using clippers.
- Styptic powder
- An astringent powder applied to small shaving nicks to contract tissue and stop minor capillary bleeding; it does not replace a bandage on larger cuts.
- Patch test
- A small amount of a chemical product applied to the skin 24 to 48 hours before a service to check for an allergic reaction.
- Strand test
- Processing a small cutting of the client's hair with the intended chemical to predict timing, strength, and result before the full service.
- Neutralizer in waving
- An acidic solution, usually hydrogen peroxide or sodium bromate, that rebuilds disulfide bonds in the new curl shape and stops the waving action.
- Relaxer retouch
- Chemical relaxer applied only to new growth and never pulled through previously relaxed hair, which prevents overlap, overprocessing, and breakage.
- Hair color level system
- A scale from 1 for black to 10 for lightest blonde that describes how light or dark a hair color is, independent of its tone.
- Developer volume
- The strength of hydrogen peroxide: 10 volume deposits color, 20 volume lifts about one level, 30 lifts two to three, and 40 lifts three to four.
- Hair structure layers
- Cuticle is the outer scaly layer, cortex is the bulk containing pigment and disulfide bonds, and medulla is the central core often absent in fine hair.
- Hair growth cycle
- Anagen is the 2 to 6 year growth phase, catagen is a short transition, and telogen is the resting phase when the hair sheds.
- pH scale
- A 0 to 14 scale where 7 is neutral, below 7 is acidic, above 7 is alkaline, and each whole number is a tenfold change in concentration.
- Bacteria shapes
- Cocci are round bacteria, bacilli are rod-shaped, and spirilla are spiral; pathogenic types cause disease while nonpathogenic types do not.
- Skin types
- The four facial skin types are normal, dry (alipidic), oily, and combination, classified by pore size, oil production, and moisture level.
- Fitzpatrick scale
- A skin typing scale from I to VI based on response to sun exposure; higher types contain more melanin and burn less easily.
- Facial massage movements
- Effleurage is light gliding stroking, petrissage is kneading, tapotement is rapid tapping, and friction is small circular pressure on the skin.
- Alopecia areata
- A patchy, autoimmune form of hair loss; the barber does not treat it and refers the client to a physician for diagnosis and care.
