Cuticle

The overlapping protective outer structure of a hair fibre, distinct from its cortex and from surrounding living scalp tissue.

Cortex

The main structural region of a hair fibre contributing strength, elasticity and natural pigment, with condition affected by prior treatment.

Medulla

A central region that can occur in some hair fibres but is not a required hollow tube in every individual hair.

Porosity

A fibre property concerning uptake and retention of water or products, which can vary along previously treated or damaged lengths.

Elasticity

The ability to extend and recover under stated conditions, interpreted separately from permanent damage and without forceful destructive testing.

Guide

A reference section used to control length or shape during a haircut, which may remain stationary or travel between sections.

Elevation

The way a section is lifted relative to an identified haircutting reference, interpreted together with distribution, tension and cutting angle.

Overdirection

Moving hair away from its natural fall or specified reference position to influence the distribution of length and weight.

Oxidation

A chemical process relevant to pigment development or lightening in specified hair systems, whose actual preparation requires compatible product instructions.

Reduction

A chemical process used in certain waving systems to modify disulfide structure before the product-specified subsequent reshaping process.

Strand assessment

An assessment of a small hair section for the intended system, which informs fibre response without guaranteeing every future result or reaction.

Surfactant

A formulation ingredient whose surface activity can assist cleansing, wetting or emulsification according to the complete product chemistry.

Emulsion

A system with one liquid dispersed through another continuous liquid phase, stabilized by suitable ingredients rather than simple permanent mixing.

Humectant

A component that binds water in a formulation or at the treated surface, whose practical effect depends on the whole product and environment.

Emollient

A component that softens and smooths the feel of a surface, distinct from a medical claim to regenerate damaged tissue.

Occlusive component

A formulation component that can reduce water loss through its surface effect, without establishing suitability for every skin condition.

Contact time

The product-specified exposure period needed for a stated process under its actual conditions, not a universal interval for all disinfectants.

Cross-contamination

Transfer of material or microorganisms between people, tools, products or surfaces through handling or an inadequately controlled workflow.

Contraindication

A relevant condition that can preclude or modify a proposed service, requiring actual product, professional and jurisdictional assessment.

Exposure record

A factual account of an unexpected contact or reaction, including the product, timing, observations and actions actually taken.

Cleaning

The removal of soil and debris through an appropriate process, often needed before further disinfection or sterilization can work as intended.

Disinfection

A specified process applied under appropriate product and equipment conditions, distinct from simply removing visible debris or assuming sterility from appearance.

Sterilization

A validated processing objective requiring the applicable cycle conditions, monitoring, handling, and barrier integrity rather than merely warming equipment.

Single use

An intended-use designation that does not become validated reuse simply because an item looks clean, is reversed, or receives an improvised wipe.

Recontamination

Introduction of contamination after an item or area has been processed, possible through hands, gloves, storage, splashes, or uncontrolled workflow.

Consultation

The communication and assessment process clarifying goals, relevant history, observations, suitability, informed agreement, and the service plan before and after treatment.

Scope of practice

The services and activities actually permitted for the provider and setting under the relevant jurisdiction, qualifications, and other applicable requirements.

Dilution ratio

A specified relationship between concentrate and diluent that must clearly distinguish water parts from total parts and does not authorize otherwise prohibited mixing.

Traceability

The ability to connect a service or processing event with the relevant client, product, equipment, measurements, timing, and actions actually recorded.

Adverse response

An unwanted or concerning reaction requiring an appropriate service or exposure response, factual documentation, and further clinical help when indicated.
