Disinfection vs. sterilization

Disinfection destroys most pathogens on nonporous surfaces but not spores; sterilization destroys all microbial life, including spores, and is used for items that contact broken skin.

EPA registration number

The number on a disinfectant label confirming the product has met EPA efficacy requirements for its stated claims, such as killing HIV-1 and hepatitis B.

Exposure control plan

A written shop document describing how blood and body-fluid exposures are prevented, reported, and followed up, including hepatitis B vaccination availability and post-exposure medical evaluation.

Single-use porous items

Towels, neck strips, cotton, and similar absorbent items that cannot be reliably disinfected; they are used once and then laundered or discarded.

Anagen phase

The active growth phase of the hair cycle, lasting years, during which the follicle produces hair and chemical services have the greatest impact on the strand.

Telogen phase

The resting phase of the hair cycle, lasting about three months, ending when the old hair sheds and a new anagen hair begins to grow.

Hair porosity

The ability of the cuticle to absorb and hold moisture; porous hair takes color quickly and fades quickly, so lower-volume developer and shorter timing are used.

Elasticity test

A wet strand is stretched to about 1.5 times its length; normal hair returns, while hair that snaps is overprocessed and should not receive further chemical service.

Surfactant action

Shampoo molecules have a water-loving head and an oil-loving tail; the tail binds sebum and the head binds water so oil lifts and rinses away.

Shampoo water temperature

Warm water near 100-105 F cleanses effectively without stripping color or irritating the scalp; hot water increases color fading and scalp dryness.

Scalp massage contraindications

Inflamed, broken, infected, or undiagnosed scaly skin should not be massaged or treated; refer the client rather than proceeding with the service.

Deep conditioning treatment

A concentrated product applied to mid-shaft and ends, often with heat or time, to restore moisture and smooth the cuticle after chemical or thermal stress.

Guideline (first cut)

The initial cut that sets the length and elevation for the entire subsection; every following subsection is cut to match it for balance.

Elevation in haircutting

The angle at which hair is held away from the head: 0 degrees builds weight, 45 degrees layers, 90 degrees creates uniform layers, and 180 degrees creates long layers.

Cross-checking

Cutting perpendicular to the previous section to verify the line is even before finishing; it reveals uneven areas that the original section angle hid.

Texturizing

Techniques such as point cutting, notching, and slicing that remove bulk and soften a line without shortening the overall perimeter length.

Shaving against the grain

A second pass in the opposite direction of hair growth that gives a closer shave but raises irritation risk, so it is used only on tolerant skin.

Beard neckline placement

The line is set about one finger above the Adam's apple and follows a natural curve between the jaw and the collarbone, trimmed from longest guard down.

Shaving contraindications

Moles, skin tags, active acne, cold sores, sunburn, and recently treated skin are skipped or avoided; the razor works around them to prevent cuts and spread of infection.

Styptic use

After a nick, pressure with clean gauze stops bleeding and an antiseptic styptic seals the cut; the contaminated blade is discarded or disinfected before reuse.

Fitzpatrick scale

A six-type classification of skin response to sun exposure; types I and II burn easily and require high sun protection and gentle exfoliation.

Effleurage

A gliding massage movement applied with light to firm pressure that warms tissue and moves fluid; it opens and closes most facial massage routines.

Petrissage

A kneading massage movement that compresses and lifts tissue to increase circulation and relax muscles; it is used on the cheeks, jaw, and neck.

Facial massage direction

Upward and outward strokes on the face follow muscle and lymph flow, while neck strokes move downward toward the clavicle to encourage drainage.

Color wheel neutralizing

Complementary colors cancel each other: violet cancels yellow, blue cancels orange, and green cancels red, which is the basis of toner formulation.

Developer volume and lift

Ten volume deposits color only, 20 lifts one to two levels, 30 lifts two to three, and 40 lifts three to four, with more lift causing more cuticle damage.

Patch test

A small amount of color or relaxer product applied 24-48 hours before service to detect allergic reaction; a positive reaction cancels the service.

Relaxer neutralization

After processing, the relaxer is rinsed and a neutralizing shampoo restores pH and stops bond breakdown; incomplete neutralization causes continued damage and breakage.

Disulfide bond

A strong chemical bond between keratin strands that gives hair its shape; perms and relaxers break and reform it to change curl or straightness.

Hydrogen bond

A temporary bond broken by water and reformed on drying; it is the basis of wet setting and blow-dry shaping of hair.

Hair bulb and papilla

The bulb is the rounded base of the follicle containing the matrix, and the papilla supplies it with blood and nutrients for growth.

Minnesota Board of Barber Examiners

The state agency that licenses barbers and shops, sets sanitation and continuing education rules, and investigates complaints; its published rules control practice.
