AZ Barber cheat sheet

Elevation guide: 0° = blunt one-length line, 45° = graduated or stacked, 90° = uniform layers, 180° = long layers with the greatest length shift.

Clipper guard length in inches = guard number × 1/8 in, so #1 = 1/8 in, #2 = 1/4 in, #3 = 3/8 in, and #4 = 1/2 in.

Blend a weight line with clipper-over-comb or shear-over-comb; the comb acts as a moving guard and the blade rides flat on the comb teeth.

Cross-check each section by cutting or clipping it again at 90° to the original part line to reveal uneven lengths.

Texturizing (point cutting, notching, slithering) removes bulk inside a shape without shortening the perimeter line.

A taper keeps weight in the interior and shortens only the lower edge, while a fade blends continuously down to skin or a #0 length.

Average scalp hair grows about 1/2 inch (1.25 cm) per month, so a #4 (1/2 inch) clipper cut is roughly one month of growth.

Round faces gain from height at the crown and close side volume; long faces gain from side width and a lower, flatter crown.

Implements must be cleaned of hair and product with soap and water and dried before immersion, because debris shields microbes from the disinfectant.

Disinfectants must be EPA-registered hospital-grade products mixed at the label dilution, and implements must be fully immersed for the label contact time (commonly 10 minutes).

Wet sanitizer means a closed container of disinfectant solution; dry sanitizer means a clean, closed, dry cabinet, and a dry cabinet alone does not disinfect.

Porous items cannot be disinfected and are single-use: cotton, tissues, wooden sticks, neck strips, paper towels, and used razor blades.

UV cabinets are not an acceptable substitute for chemical disinfection of implements.

Wash hands with soap and warm water for at least 20 seconds before and after every client and after handling soiled items.

Blood or body-fluid exposure: stop the service, don gloves, apply antiseptic and a bandage, then clean the area and disinfect all contaminated tools and surfaces with a tuberculocidal product.

Electrical clippers are cleaned by brushing off hair and wiping the housing with disinfectant; the motor and cord are never immersed.

A clean towel or neck strip must separate the client's skin from the cape, and capes must be changed or laundered between clients.

Hold the razor at roughly a 30° angle to the skin, flat enough not to scrape and steep enough to cut hair.

Shave in the direction of hair growth first; against-the-grain passes give a closer shave but increase razor bumps and ingrown hairs.

A hot moist towel before lathering softens the beard and relaxes skin; a cool towel afterward tightens pores and soothes.

Stretch the skin taut ahead of the razor and use short strokes; never shave over moles, inflamed skin, or broken skin.

Pseudofolliculitis barbae (razor bumps) is common with tightly curled hair, so advise a with-the-grain shave and no razor-close finish.

A styptic (alum) product stops small nicks; apply it with a clean applicator and never re-dip a used applicator into the container.

For beard shaping, remove bulk first, then define the outline with a trimmer and use the comb as a guard for even length.

A straight razor is stropped before the shave and cleaned and disinfected after; the blade is wiped away from the edge, never across it.

Developer strength: 10 volume ≈ 3% hydrogen peroxide, 20 volume = 6%, 30 volume = 9%, 40 volume = 12%; higher volume lifts more and damages more.

Color levels run from 1 (black) to 10 (lightest blonde), and each level is one step of lightness.

Complementary colors cancel unwanted tone: blue neutralizes orange, violet neutralizes yellow, green neutralizes red.

Patch test 24 to 48 hours before a first-time color or lightener application and record the result on the client card.

Permanent waves work in two stages: the reducing agent (thioglycolate or GMTG) breaks disulfide bonds, and the neutralizer rebuilds them in the new shape.

Relaxers are sodium hydroxide (lye, pH about 13) or guanidine/lithium no-lye systems; the scalp is based, product goes on new growth only, and thorough neutralizing stops processing.

A strand test predicts timing and outcome and is required whenever the client's chemical history is unknown.

Do not lighten hair carrying metallic salts or compound henna, because the reaction is unpredictable and can cause severe breakage.

Record formula, developer, processing time, and result for every chemical service.

Arizona barbering law is set in Arizona Revised Statutes Title 32, and the Board of Barbers adopts detailed implementing rules in the Arizona Administrative Code.

Barbering in Arizona requires a state barber license, and a shop must hold a shop license with licenses displayed where clients and inspectors can see them.

Practicing barbering without a license, or a shop employing an unlicensed person, is unlawful and can bring Board discipline plus criminal penalties.

The Board may enter and inspect a licensed shop during business hours and may cite sanitation, equipment, or record violations found on inspection.

Only services within the statutory definition of barbering may be performed; medical treatment or diagnosis of skin and scalp disease is outside the barber's scope.

Shops must have hot and cold running water, adequate lavatory facilities, and hand-washing facilities available to staff.

Board discipline ranges from a letter of reprimand to civil penalties, suspension, or revocation of the license.

A license must be renewed by the Board's deadline with the required fee; working on an expired license is treated as unlicensed practice.

Hair layers: cuticle (protective outer scales), cortex (strength, elasticity, melanin), and medulla (soft core that may be absent).

pH reference: hair and scalp about 4.5 to 5.5, shampoos slightly acidic, relaxers 12 to 14, lighteners alkaline.

Low-porosity hair has a tightly closed cuticle, resists moisture, and processes slowly; high-porosity hair absorbs and loses moisture quickly.

Elasticity test: a wet strand should stretch about half its length and return; hair that snaps is over-processed and should not receive chemicals.

Contagious conditions that stop a service and require referral: tinea (ringworm), lice, impetigo, and active herpes lesions.

Non-contagious scalp conditions such as pityriasis (dandruff), seborrheic dermatitis, and psoriasis may allow service with mild products plus referral.

Shampoo procedure: wet with warm water, emulsify shampoo in the palms, lather the scalp with the pads of the fingers rather than the nails, and rinse thoroughly.

Scalp massage manipulations are effleurage, petrissage, tapotement, friction, and vibration.

Protein conditioners replace lost keratin while moisturizing conditioners attract and hold water; over-proteinized hair feels stiff and snaps.

Massage manipulations: effleurage (light gliding), petrissage (kneading), tapotement (percussion), friction, and vibration.

Facial massage strokes move upward and outward along the muscle direction, with light pressure on thin skin around the eyes and temples.

Contraindications to facial massage: open lesions, active acne, sunburn, recent peels or waxing, fever, and undiagnosed lumps; refer instead.

Skin types are normal, dry, oily, combination, and sensitive, and product selection follows the observed type rather than the client's claim.

Clay and mud masks absorb excess oil and suit oily or combination skin; cream and gel masks add moisture and suit dry or sensitive skin.

Steam and warm towels soften comedones and increase circulation; keep the heat moderate and never leave the client unattended.

Drape the client so only the face and neck are exposed, and keep all products out of the eyes.

Ancillary barber services such as eyebrow trimming, ear and nose hair trimming, and facial massage are permitted within scope, but diagnostic or medical procedures are not.

Consultation sequence: hair history and prior chemical services, medications and allergies, daily styling routine, desired result, then confirm price and time.

Scope of practice: barbers may describe what they observe but may not diagnose or treat disease; suspected infection is referred to a physician.

Confidentiality: client information and service records are not shared with others without the client's consent.

OSHA Hazard Communication requires safety data sheets for every chemical product in the shop to be on file and accessible to employees.

OSHA Bloodborne Pathogens rules require an exposure control plan, gloves, and training for employees with occupational exposure to blood.

Quote the price and expected time before starting, and disclose added charges before performing additional services.

Document each service on the client card: formula, products, timing, outcome, and any adverse reaction.

Handle complaints by listening, restating the concern, offering a remedy within shop policy, and recording the resolution.
