Disinfection versus sterilization

Disinfection destroys most pathogenic organisms on nonporous surfaces but not necessarily bacterial spores; sterilization destroys all microorganisms including spores and is used on items that penetrate skin.

EPA hospital-grade disinfectant

A disinfectant registered with the EPA that carries a tuberculocidal claim, required in barber shops for implements and surfaces contaminated with blood or body fluids; label contact time must be followed.

Wet sanitizer container

A closed container holding an EPA-registered disinfectant solution in which pre-cleaned, nonporous implements are fully immersed for the label's stated contact time, commonly 10 minutes for quats.

Blood spill procedure

Stop the service, put on gloves, apply disinfectant, absorb the spill with disposable towels, double-bag the waste, then wash hands with soap and water before continuing with any client.

Single-use items

Neck strips, cotton, wooden applicators, tissues, and razor blades cannot be disinfected and must be discarded after one client; they must never be reused or stored with clean implements.

Anagen phase

The active growth phase of the hair cycle, lasting roughly two to six years on the scalp; about 90 percent of scalp hairs are in this phase at any given time.

90-degree elevation

Holding hair out perpendicular to the scalp while cutting; it produces uniform layers because every section is cut at the same angle from the head form.

Traveling guide

A movable section of previously cut hair used as the length guide for later sections; it is used for layered and graduated cuts rather than for one-length cuts.

Clipper guard sizes

Guard numbers correspond to the hair length left behind: number 1 leaves 1/8 inch (3 mm), number 2 leaves 1/4 inch, number 3 leaves 3/8 inch, and number 4 leaves 1/2 inch.

Blunt one-length cut

Cutting with zero elevation and a stationary guide at the perimeter so all hair falls to the same level; it produces a solid form line with no layering or graduation.

Honing versus stropping

Honing grinds and restores a straight razor's edge on an abrasive stone; stropping on leather polishes and realigns the edge before each shave without removing metal.

Shaving with the grain

The first pass of a shave follows the direction of beard growth, removing the most hair with the least irritation; a second pass against the grain is closer but risks ingrown hairs.

Contraindications for shaving

Do not shave over moles, warts, inflamed or broken skin, or areas with infection; shaving these areas can spread bacteria and cause bleeding or scarring.

Styptic powder

A topical astringent applied to minor shaving nicks to stop capillary bleeding by constricting vessels; it is not a disinfectant and does not replace cleaning the area.

Sodium hydroxide relaxer pH

Lye relaxers contain sodium hydroxide at pH 12 to 14, the highest of the chemical services; they straighten hair by breaking disulfide bonds and require base cream and neutralizing shampoo.

Developer volumes

Ten-volume peroxide is 3 percent, 20-volume is 6 percent, 30-volume is 9 percent, and 40-volume is 12 percent; higher volumes lift more melanin and cause more damage.

Eumelanin and pheomelanin

Eumelanin is the brown-to-black pigment and pheomelanin the red-to-yellow pigment; the amount and ratio of both determine natural hair color and how it lifts.

Neutralizing shampoo

An acidic, low-pH shampoo used after a relaxer to stop chemical processing, remove residue, and restore the hair's normal pH; it is typically lathered three times in a relaxer service.

Thioglycolate permanent wave

An alkaline wave at pH 8 to 9.5 that uses ammonium thioglycolate to reduce disulfide bonds, then a hydrogen peroxide neutralizer to rebuild them in the new shape.

Cortex layer

The middle and thickest layer of the hair shaft, containing melanin and disulfide bonds; it gives hair strength, elasticity, and curl, and chemical services act on it.

Tinea capitis

A contagious fungal infection of the scalp causing round scaly patches and broken hairs; barbers must not treat it and should refer the client to a physician.

Hair porosity

The hair's ability to absorb moisture, determined by cuticle tightness; porous hair absorbs and releases quickly and takes color fast, while resistant hair needs more processing time.

Acid mantle

The slightly acidic film on skin and scalp at about pH 4.5 to 5.5 that inhibits bacteria and limits moisture loss; alkaline products temporarily disrupt it.

Elasticity test

Stretch a wet strand; healthy hair stretches about 50 percent of its length and returns, while low-elasticity hair snaps or stays limp, indicating damage that limits chemical services.

Effleurage

A light, continuous gliding stroke used at the start and end of a facial massage; it warms tissue, increases circulation, and follows the direction of the muscle fibers.

Facial massage contraindications

Avoid massage with fever, contagious skin disease, severe or cystic acne, recent chemical peel or waxing, and uncontrolled high blood pressure; refer such clients rather than treat them.

Tapotement

A percussion manipulation of light, rapid tapping or slapping with the fingertips or hands, used briefly on the face and more commonly on the scalp and shoulders.

Skin types

Normal, dry, oily, and combination, classified by oil production and moisture; combination skin is oily in the T-zone and normal or dry on the cheeks.

NC Board of Barber Examiners

The state agency created under North Carolina General Statutes Chapter 86A that licenses barbers and shops, sets sanitation rules, approves schools, and disciplines licensees.

NC barber training hours

North Carolina requires 1,528 clock hours of barber curriculum at a licensed school before a candidate may sit for the Board's licensing examination.

Grounds for discipline

The Board may suspend or revoke a license for practicing without a license, unsanitary practices, intoxication on the job, fraud in obtaining a license, or other misconduct.

Shop inspection authority

Board inspectors may enter a licensed barber shop during business hours to inspect sanitation, equipment, and licenses; refusing an inspection can lead to disciplinary action.
