Galvanic electrolysis

A modality in which direct current passes through a needle and body tissue, producing a chemical reaction at the follicle base that destroys the hair-growing cells.

Related: Lye, Anode, Thermolysis
Thermolysis

A modality that uses high-frequency alternating current to generate heat at the needle tip, coagulating tissue around the follicle to disable hair growth.

Related: Galvanic electrolysis, Blend method, Hair bulb
Blend method

A modality combining galvanic direct current and high-frequency current so that lye is produced while heat accelerates and spreads the chemical reaction within the follicle.

Related: Galvanic electrolysis, Thermolysis, Lye
Lye

Sodium hydroxide created when direct current reacts with salt and water in body tissue; this caustic substance destroys the cells that produce hair.

Related: Galvanic electrolysis, Blend method, Anagen phase
Anode

The positive electrode in a direct-current circuit; in electrolysis it is usually the inactive dispersive pad placed on the client's skin to complete the circuit.

Related: Cathode, Galvanic electrolysis, Indifferent electrode
Cathode

The negative electrode in a direct-current circuit; in electrolysis the needle acts as the cathode, where the lye-producing reaction occurs.

Related: Anode, Lye, Galvanic electrolysis
Indifferent electrode

A conductive pad or metal contact placed on the client's skin to complete the electrical circuit during treatment; also called the dispersive or return electrode.

Related: Anode, Cathode
Insertion

The precise placement of a probe into a hair follicle alongside the hair shaft, following the natural angle and depth of the follicle without puncturing the skin surface.

Related: Probe, Hair follicle, Insertion depth
Probe

The fine, sterile, single-use needle used to deliver current to the follicle during electrolysis; also called a filament or needle.

Related: Insertion, Sterilization, Single-use device
Insertion depth

The distance the probe travels into the follicle, ideally reaching the bulge and bulb region where the target cells reside, judged from the visible hair length and follicle angle.

Related: Insertion, Hair bulb, Bulge region
Epilation

Removal of hair by reaching below the skin surface to destroy or extract the root, as distinct from depilation, which removes hair only at the surface.

Related: Depilation, Hair bulb
Depilation

Removal of hair at or just above the skin surface without destroying the follicle, such as shaving or trimming.

Related: Epilation
Treatment plan

An individualized written schedule of sessions, modalities, and expected outcomes developed from client history, hair and skin assessment, and agreed goals, updated as treatment progresses.

Related: Client consultation, Informed consent, Modality
Client consultation

A structured pre-treatment interview and assessment covering health history, medications, skin condition, hair type, prior hair removal, and expectations, used to plan safe and effective care.

Related: Treatment plan, Informed consent, Medical history
Informed consent

A client's voluntary agreement to treatment after receiving a clear explanation of the procedure, its risks, benefits, alternatives, and expected aftercare, documented before care begins.

Related: Client consultation, Scope of practice, Confidentiality
Scope of practice

The legally defined set of activities an electrologist is trained and licensed or certified to perform, beyond which the client must be referred to a physician or other qualified professional.

Related: Referral, Informed consent, Standard of care
Standard of care

The level and quality of care a reasonably prudent electrologist with similar training would provide under comparable circumstances, used as the benchmark for professional conduct.

Related: Scope of practice, Code of ethics, Negligence
Code of ethics

A profession's formal set of principles governing honesty, client welfare, confidentiality, competence, and professional boundaries that members agree to uphold.

Related: Standard of care, Confidentiality, Professional boundaries
Confidentiality

The ethical and often legal duty to protect a client's personal, health, and treatment information from disclosure without proper authorization or a legal requirement.

Related: Informed consent, Code of ethics, Client record
Professional boundaries

The appropriate limits on the relationship between electrologist and client that keep the interaction focused on treatment and prevent exploitation, undue familiarity, or conflicts of interest.

Related: Code of ethics, Scope of practice
Referral

Directing a client to a physician or other qualified professional when a condition, medication, or risk factor lies outside the electrologist's training or legal scope.

Related: Scope of practice, Contraindication
Client record

A documented account of consultations, treatment parameters, skin reactions, and aftercare instructions kept for each client, supporting continuity of care and legal defensibility.

Related: Confidentiality, Treatment plan
Hair follicle

A tube-like invagination of the epidermis and dermis from which a hair grows, containing the bulb, bulge, sebaceous gland attachment, and blood supply that support the hair.

Related: Hair bulb, Bulge region, Anagen phase
Hair bulb

The swollen, rounded base of the hair follicle containing the matrix of actively dividing cells and the dermal papilla that nourishes hair growth.

Related: Dermal papilla, Hair follicle, Anagen phase
Dermal papilla

A small cone of connective tissue and capillaries at the base of the follicle that supplies nutrients to the hair matrix and is essential for hair production.

Related: Hair bulb, Anagen phase
Bulge region

A swelling on the upper portion of the follicle that houses epithelial stem cells and the attachment of the arrector pili muscle; a key target for permanent hair removal.

Related: Hair follicle, Insertion depth
Anagen phase

The active growth stage of the hair cycle, when the follicle is deepest and most vascular and hair is most responsive to electrolysis.

Related: Telogen phase, Catagen phase, Hair bulb
Catagen phase

A short transitional stage of the hair cycle in which growth stops, the follicle shortens, and the lower portion begins to break down.

Related: Anagen phase, Telogen phase
Telogen phase

The resting stage of the hair cycle, when the hair is no longer growing and is eventually shed, leaving the follicle shallower and often less responsive to treatment.

Related: Anagen phase, Catagen phase
Vellus hair

Fine, short, lightly pigmented hair covering much of the body, typically lacking a deep bulb and usually not the target of electrolysis.

Related: Terminal hair, Hirsutism
Terminal hair

Coarse, longer, and usually pigmented hair with a deep follicle and medullated shaft, the typical target of electrolysis on the face and body.

Related: Vellus hair, Hair follicle
Hirsutism

Excessive growth of coarse, dark terminal hair in a male-pattern distribution on a woman, often related to hormonal conditions and warranting medical referral.

Related: Terminal hair, Referral
Skin lesion

Any area of altered skin tissue, such as a mole, cyst, or growth; suspicious or undiagnosed lesions should not be treated and should be referred for evaluation.

Related: Referral, Contraindication
Contraindication

A condition, medication, or circumstance that makes treatment inadvisable or unsafe until resolved, modified, or cleared by a physician.

Related: Referral, Medical history
Medical history

A record of a client's past and current health conditions, surgeries, medications, and allergies, reviewed to identify risks and contraindications before treatment.

Related: Client consultation, Contraindication
Sterilization

A validated process that destroys all microbial life, including bacterial spores, on reusable instruments; required for items that penetrate skin or contact blood.

Related: Disinfection, Autoclave, Single-use device
Disinfection

A process that reduces or eliminates many pathogenic microorganisms on surfaces or non-critical items, but does not reliably destroy all spores.

Related: Sterilization, Standard precautions
Autoclave

A device using pressurized steam and high temperature to sterilize reusable instruments; its effectiveness is verified with biological and chemical indicators.

Related: Sterilization, Spore test
Spore test

A biological monitoring method using resistant bacterial spores to confirm that a sterilizer is achieving true sterilization, typically performed on a regular schedule.

Related: Autoclave, Sterilization
Single-use device

An instrument, such as a probe, intended for one client only and discarded after use to prevent cross-contamination.

Related: Probe, Sterilization
