- Disinfection
- A process using an EPA-registered product that destroys most pathogens on nonporous surfaces and implements, but does not necessarily destroy bacterial spores.
- Sterilization
- The complete destruction of all microbial life, including spores, usually achieved by an autoclave using steam under pressure.
- Tuberculocidal disinfectant
- A hospital-strength disinfectant proven to kill the tuberculosis bacterium; required for implements that contact blood or body fluids.
- Safety Data Sheet
- A document supplied with each chemical product listing hazards, safe handling, first aid, and disposal information; must be kept on site.
- Anagen phase
- The active growth phase of the hair cycle, lasting several years, during which cells in the hair bulb divide rapidly.
- Telogen phase
- The resting phase of the hair cycle, after which the old hair is shed and a new one begins to grow.
- Elasticity test
- A wet strand is stretched to judge whether it returns to length; poor return indicates over-processing or damage.
- Porosity
- The hair's ability to absorb moisture; high porosity means a raised cuticle, while low porosity resists moisture absorption.
- Elevation
- The angle at which hair is held away from the head while cutting; it determines the amount of weight and layering in the shape.
- Stationary guide
- The first section cut that sets the length and does not move; all later sections are cut to match it.
- Graduated form
- A haircut built with slight elevation that stacks length at the perimeter and creates a wedge or stacked effect.
- Cross-checking
- Cutting or examining the same area from a different direction to confirm the cut is balanced and even.
- Parietal ridge
- The widest curve of the head, located between the front hairline and the crown; a key reference point for sectioning.
- With the grain
- Shaving in the direction the hair grows; this reduces friction and irritation compared with shaving against growth.
- Razor honing
- Grinding a straight razor on a stone to restore the edge, followed by stropping on leather to polish it.
- Beard neckline
- The lower boundary of a beard, placed roughly one finger-width above the Adam's apple and curved to follow the jaw.
- Shaving contraindications
- Skin conditions such as open lesions, cold sores, or acne that make shaving unsafe because infection or injury may result.
- Developer volume
- The strength of hydrogen peroxide used with color; 20 volume lifts one to two levels, while 40 volume lifts three to four.
- Patch test
- A small amount of color product applied 24 to 48 hours before service to check for an allergic reaction.
- Strand test
- A test on a small section of the client's hair to predict processing time, developer strength, and final color result.
- Semipermanent color
- A deposit-only color that does not lift natural pigment and gradually fades over several shampoos.
- Disulfide bonds
- Chemical bonds between keratin strands that give hair strength; relaxers and permanent waves break and reform them.
- Stratum corneum
- The outermost layer of the epidermis, made of flattened keratinized cells that form the skin's protective barrier.
- Dermis
- The middle skin layer containing blood vessels, nerves, sebaceous glands, and hair follicles; it supports the epidermis.
- Sebaceous gland
- A gland attached to the hair follicle that secretes sebum to lubricate the skin and hair shaft.
- Arrector pili muscle
- A small muscle attached to the hair follicle that contracts in cold or emotion, producing goose bumps.
- Hair cortex
- The middle layer of the hair shaft, containing keratin bundles and melanin; it gives hair strength, elasticity, and color.
- Booth renter
- An independent operator who pays rent for space in a shop and manages their own clients, supplies, and taxes.
- Pricing formula
- Service price equals supply cost plus labor plus overhead plus profit; retail price equals product cost times a markup.
- License display
- Alabama rules require current individual and shop licenses to be posted in plain view where services are performed.
- Board inspection authority
- Alabama regulators may enter a licensed shop during business hours to check sanitation, licensing, and compliance with rules.
- Client consultation record
- Documentation of allergies, medications, prior chemical services, and the agreed result, kept before performing a service.
