Sanitation, Sterilization, and Safety

  • Sanitizing reduces pathogens on surfaces to a safe level; disinfection destroys most pathogens on nonporous implements; sterilization destroys all microbial life including spores.

  • An EPA-registered hospital disinfectant with a tuberculocidal claim is required for items that contact blood or body fluids; quats are used for general surface disinfection.

  • Blood and body-fluid spills: wear gloves, absorb with disposable towel, clean with detergent, disinfect with EPA hospital disinfectant, and dispose of materials in a sealed bag.

  • Implements must be cleaned of debris, then completely immersed in disinfectant for the label's contact time (commonly 10 minutes) before reuse.

  • Porous items that contact blood or body fluids (towels, cotton, neck strips) are single-use and must be discarded, never disinfected and reused.

  • Electrical tools: unplug before cleaning, keep motor and cords free of water and hair, and inspect cords for fraying; damaged cords are removed from service.

  • Hand washing uses soap and warm running water with friction for at least 20 seconds; an alcohol-based hand sanitizer is not a substitute when hands are visibly soiled.

  • Material Safety Data Sheets (SDS) must be kept on site for every chemical product and be accessible to workers.

Hair and Scalp Care and Treatments

  • Hair is roughly 90 percent protein (keratin); the cortex provides strength, elasticity, and pigment, while the medulla is the innermost layer and may be absent in fine hair.

  • The hair growth cycle: anagen (active growth, years), catagen (transition, weeks), and telogen (resting/shedding, months); normal daily shedding is about 50-100 hairs.

  • Scalp types are classified as normal, dry, oily, or combination; treatment selection follows the observed condition, not the client's preference.

  • A scalp analysis is performed before a treatment; contraindications include abrasions, open lesions, recent chemical burns, and contagious conditions such as ringworm or lice.

  • Shampoo pH: lower pH (acid-balanced, ~4.5-5.5) smooths the cuticle; higher-alkaline shampoos swell the cuticle and are used for deep cleansing.

  • Conditioners work by depositing on the cuticle, lowering friction and improving combability; protein treatments temporarily fill gaps in damaged, porous hair.

  • Hair elasticity test: a wet strand should stretch and return; hair that snaps immediately lacks elasticity and signals over-processing.

  • Porosity test: hair that absorbs water quickly is highly porous (damaged cuticle); hair that repels water is low porosity and resists moisture.

Haircutting and Styling

  • The four basic haircut forms are solid (one length), graduated, layered, and uniform (same length throughout); each produces a distinct silhouette.

  • Elevation (projection) is the angle at which hair is held from the head; 0 degrees builds weight, 45 degrees graduates, 90 degrees layers, and 180 degrees removes the most weight.

  • Distribution describes where hair is directed relative to its section: natural falling, shifted, or perpendicular.

  • A guide (guideline) is the first cut strand that establishes length; a stationary guide does not move, while a traveling guide moves with each section.

  • Blunt or club cutting creates a strong, solid perimeter line; point cutting and slide cutting soften weight and texturize ends.

  • Cross-checking means cutting the same area from a different direction to verify balance and evenness.

  • The apex is the highest point of the head; the parietal ridge is the widest curve, and the occipital bone marks the curve at the back of the skull.

  • Blow-dry styling: rough-dry to about 80 percent, direct airflow from scalp to ends along the cuticle, and use a nozzle for control; thermal tools should be set according to hair texture and condition.

Shaving, Beard Trimming, and Facial Hair Services

  • Shaving lather softens the hair and provides glide; wet the beard area with warm water before lathering to soften keratin.

  • Shave in the direction of hair growth (with the grain) to reduce irritation; against-the-grain passes increase the risk of razor burn and ingrown hairs.

  • Straight razor: hold at a shallow angle (about 30 degrees) and stretch the skin taut; stroke with light pressure and rinse the blade frequently.

  • A honed and stropped razor has a smooth, keen edge; a dull blade drags and nicks, so it must be replaced or re-honed.

  • Beard design follows face shape: fuller sides balance a narrow face, while shorter sides slim a round face; the neckline sits about one finger-width above the Adam's apple.

  • After shaving, apply a soothing astringent or toner and a moisturizer; alcohol-based products may sting freshly shaved skin.

  • Contraindications for shaving include acne lesions, cold sores, moles, and ingrown hairs; shaving over them can spread infection or cause injury.

  • Single-use razor blades and disposable towels must be discarded after each client; reusable razors are cleaned and disinfected per label directions.

Chemical Services (Coloring, Lightening, and Texture Services)

  • The pH scale runs 0-14; hair is naturally acidic (about 4.5-5.5), and chemical services raise pH to swell the cuticle and allow penetration.

  • Permanent hair color uses an aniline derivative dye plus hydrogen peroxide developer; the developer lifts natural pigment and deposits the new color inside the cortex.

  • Developer volumes: 10 volume (3 percent) deposits only, 20 volume (6 percent) lifts 1-2 levels, 30 volume (9 percent) lifts 2-3 levels, and 40 volume (12 percent) lifts 3-4 levels.

  • Semipermanent color deposits without lifting and fades over several shampoos; temporary color coats the cuticle and washes out in one shampoo.

  • Lightening (bleach) removes pigment; the process stops at the desired level, and toner is applied afterward to neutralize unwanted warmth.

  • Patch test for color: apply product behind the ear or inner elbow 24-48 hours before the service and check for redness or swelling.

  • A strand test determines processing time, developer strength, and expected result on the client's specific hair.

  • Relaxers and permanent waves break and reform disulfide bonds; a neutralizer or neutralizing shampoo stops the chemical action and restores pH.

Anatomy, Physiology, and Skin Structure

  • The skin has three main layers: epidermis (outer, avascular), dermis (contains nerves, glands, and blood vessels), and subcutaneous (fat) layer.

  • The epidermis's outermost layer is the stratum corneum, composed of flattened, keratinized cells that provide the barrier.

  • The dermis contains collagen (strength) and elastin (elasticity) fibers, along with sebaceous glands, sweat glands, and hair follicles.

  • The hair follicle is a tube-like depression in the skin; the hair bulb at its base contains the matrix where cells divide and hair grows.

  • The sebaceous gland secretes sebum, which lubricates skin and hair; overactive sebum is associated with oily scalp and acne.

  • The arrector pili muscle attaches to the follicle and contracts in cold or emotion, causing goose bumps.

  • The three main layers of the hair shaft are the cuticle (outer protective scales), cortex (bulk and pigment), and medulla (central core).

  • Bones of the skull relevant to barbering include the frontal, parietal, temporal, occipital, and zygomatic (cheekbone) bones.

Shop Management, Business Practices, and Alabama Barber Laws and Regulations

  • Alabama barbering is regulated by the Alabama Board of Barbering and Cosmetology; a license is required to practice or operate a shop.

  • A shop license and individual licenses must be displayed in plain view at the establishment.

  • Alabama requires barber licenses to be renewed on a set cycle; practicing on an expired license is a violation subject to penalty.

  • Sanitation requirements include approved disinfectants, covered waste containers, and clean towels for each client; inspectors may enter during business hours.

  • Recordkeeping: keep client service records and chemical product SDS on file; retain records as required by the Board.

  • Business basics: price of a service = cost of supplies + labor + overhead + profit; a markup is applied to product cost to set retail price.

  • A booth renter pays rent for space and operates as an independent business, while an employee works under the shop owner's direction and payroll.

  • Client consultation should document allergies, prior chemical services, medications, and desired result before service begins.
