Disinfection

The use of an EPA-registered chemical product, following label contact time, to destroy most pathogenic microorganisms on hard, nonporous implements and surfaces. It is a higher level of control than sanitation but does not reliably kill bacterial spores.

Related: Sanitation, EPA-Registered Product, Bloodborne Pathogen Standard
Sanitation

A lower-level cleaning process that physically removes visible debris, oils, and many microorganisms from tools, hands, and work surfaces using soap, detergent, or an approved cleaner. It is required before disinfection or sterilization and is not a substitute for either.

Related: Disinfection, Sterilization
Sterilization

A process that destroys all microbial life, including bacterial spores, usually by autoclave steam under pressure or dry heat. In nail salons it is reserved for items that may contact broken skin or are reused invasively, such as metal pushers used on compromised tissue.

Related: Disinfection, Autoclave
Autoclave

A device that sterilizes metal implements with high-pressure saturated steam. Correct loading allows steam contact with every surface, and each cycle should be monitored with indicators; items must be cleaned and dried before processing.

Related: Sterilization, Ultrasonic Cleaner
Ultrasonic Cleaner

A unit that uses high-frequency sound waves in a cleaning solution to remove debris from the crevices of implements before disinfection or sterilization. It cleans but does not disinfect or sterilize on its own.

Related: Autoclave, Sanitation
EPA-Registered Product

A hospital-strength disinfectant whose label carries an EPA registration number and claims effectiveness against specific pathogens. Technicians must mix it at the labeled dilution and leave it wet on the surface for the full stated contact time.

Related: Disinfection, Contact Time
Contact Time

The number of minutes a disinfectant must remain visibly wet on an implement or surface to achieve its labeled kill claims. Shortening this time, or letting the item dry early, invalidates disinfection.

Related: EPA-Registered Product, Disinfection
Bloodborne Pathogen Standard

The federal OSHA rule requiring employers to protect workers from blood and other potentially infectious materials. It mandates exposure control plans, hepatitis B vaccination offers, gloves, handwashing, sharps handling, and spill cleanup procedures.

Related: Universal Precautions, Personal Protective Equipment
Universal Precautions

The practice of treating all blood, body fluids, and non-intact skin as potentially infectious regardless of a client's known health status. Gloves are worn for any service where contact with these materials is reasonably anticipated.

Related: Bloodborne Pathogen Standard, Personal Protective Equipment
Personal Protective Equipment

Items worn to block contact with hazards, including disposable gloves, safety glasses or goggles, and masks when dust or splashes are likely. Gloves are single-use and must be discarded and replaced if torn or between clients.

Related: Universal Precautions, Bloodborne Pathogen Standard
Nail Plate

The hard, translucent keratin structure covering the distal end of the finger or toe. It protects the sensitive nail bed beneath and its visible portion is the most common focus of cosmetic services.

Related: Nail Bed, Free Edge, Matrix
Nail Bed

The pinkish tissue directly beneath the nail plate, rich in blood vessels and nerves, to which the plate adheres. Damage or separation of this tissue causes pain and can lead to onycholysis.

Related: Nail Plate, Onycholysis, Lunula
Matrix

The hidden area at the base of the nail where new nail cells are produced and keratinized. Injury here can permanently distort the growing nail plate, so implements must never dig into this region.

Related: Lunula, Nail Plate, Eponychium
Lunula

The whitish, half-moon area at the proximal end of the nail plate, visible where the underlying matrix is thickest. It is normal anatomy, not a disease, and its appearance varies among individuals.

Related: Matrix, Nail Plate
Eponychium

The living skin at the base of the nail plate that forms the cuticle seal. Technicians must never cut living eponychium because it opens a portal for infection; only loose, nonliving cuticle is gently removed.

Related: Cuticle, Matrix, Paronychia
Cuticle

The thin, nonliving layer of skin that adheres to the nail plate surface at its base. Softening and careful removal of only this dead tissue is acceptable; cutting into the living eponychium is not.

Related: Eponychium, Nail Plate
Free Edge

The portion of the nail plate that extends beyond the fingertip and is filed or shaped during services. It has no underlying nail bed, so it can be filed without discomfort when healthy.

Related: Nail Plate, Nail Extension
Hyponychium

The skin seal beneath the free edge of the nail, where the nail bed meets the fingertip. It helps keep debris and pathogens out; aggressive cleaning under the free edge can break this seal.

Related: Nail Bed, Free Edge
Onycholysis

Painless separation of the nail plate from the nail bed, often appearing as a white or yellowish patch that moves forward as the nail grows. Causes include trauma, aggressive cleaning, and fungal infection; it is not a service to hide with product.

Related: Nail Bed, Onychomycosis, Contraindication
Onychomycosis

A fungal infection of the nail plate and bed, typically producing thickened, discolored, crumbly nails, often starting at the free edge. It is contagious and requires medical referral; contaminated implements and debris must be handled as infectious.

Related: Onycholysis, Contraindication, Disinfection
Paronychia

Inflammation or infection of the tissue around the nail, with redness, swelling, tenderness, and possible pus. It is often linked to cuticle damage or moisture, and the area must not be manipulated or covered until cleared by a physician.

Related: Eponychium, Contraindication
Contraindication

A condition or circumstance that makes a nail service unsafe or inadvisable, such as open lesions, active infection, severe inflammation, or an unexplained discoloration. The technician declines or postpones service and refers the client appropriately.

Related: Onychomycosis, Paronychia, Informed Consent
Informed Consent

The client's voluntary agreement to a service after being told its risks, benefits, alternatives, and expected aftercare. It is documented and obtained before procedures such as aggressive cuticle work or artificial enhancements.

Related: Contraindication, Client Consultation
Client Consultation

A structured conversation before service covering the client's goals, health history, medications, prior nail products, lifestyle, and allergies. It identifies contraindications, sets realistic expectations, and documents the agreed plan and price.

Related: Informed Consent, Contraindication
Scope of Practice

The legally permitted boundaries of what a licensed nail technician may do, such as manicuring, pedicuring, and applying enhancements. It excludes diagnosing disease, using medical devices, or performing services reserved for other licensees.

Related: Contraindication, Informed Consent
New Mexico Board of Barbers and Cosmetologists

The state regulatory body that licenses nail technicians and salons in New Mexico and enforces sanitation, continuing education, and practice standards. Candidates should verify current licensing, renewal, and inspection requirements directly with the Board.

Apex

The highest point of the nail's curved structure, located where stress is greatest during use. Proper placement and thickness at the apex give an enhancement strength, while a misplaced apex causes lifting or breakage.

Related: Stress Area, Nail Extension
Stress Area

The zone at the sidewall-to-free-edge junction where the natural nail and any enhancement take the most impact. It requires adequate but not excessive product thickness and careful blending to resist cracking and lifting.

Related: Apex, Nail Extension
Nail Extension

Any added length or structure attached to the natural nail, including tips, forms with acrylic or gel, and wraps. Success depends on correct nail preparation, controlled product placement, and a smooth transition at the stress area.

Related: Nail Tip, Stress Area, Apex
Nail Tip

A preformed plastic extension adhered to the free edge to add length before overlay. The well must fit the natural free edge without gaps or pressure, and the tip must be blended so no ledge catches or lifts.

Related: Nail Extension, Blending
Blending

The process of thinning and feathering the junction between an artificial tip or wrap and the natural nail so the transition is seamless. Poor blending produces visible ledges, lifting, and product failure.

Related: Nail Tip, Nail Wrap
Nail Wrap

A reinforcement overlay of fabric, fiberglass, or silk adhered to the nail with resin and then sealed. Wraps add strength with minimal bulk but require thorough surface preparation and careful edge sealing to prevent lifting.

Related: Blending, Nail Extension
Monomer

The liquid component of liquid-and-powder acrylic systems, typically ethyl methacrylate, that polymerizes with powder to form a hard polymer. It is a sensitizer and skin irritant, so it must be kept off skin and used with adequate ventilation.

Related: Polymer, Polymerization, Sensitization
Polymer

The powder component in acrylic systems, made of finely milled polymer beads that absorb monomer and set into a solid. Powder-to-liquid ratio controls working time, strength, and the risk of bubbles or shrinkage.

Related: Monomer, Polymerization
Polymerization

The chemical reaction in which monomer molecules link into long chains to harden acrylic or gel product. Heat, moisture, and correct mix ratio affect the reaction; an overly wet mix can cause excessive heat and skin burns.

Related: Monomer, Polymer, Curing
Curing

The setting or hardening of a product, achieved by chemical reaction in acrylics and by exposure to UV or LED light in gels. Under-curing leaves tacky, weak gel that can harbor bacteria and cause allergic reactions.

Related: Polymerization, Gel Polish
Gel Polish

A light-cured coating applied in thin layers and set under a UV or LED lamp. It must be removed by soaking or filing per manufacturer instructions; peeling it off damages the nail plate and can cause separation.

Related: Curing, Onycholysis
Sensitization

An allergic response that develops after repeated skin contact with a substance such as uncured acrylate monomer or gel. Once sensitized, the person may react to future exposures, so product must never touch skin and spills must be cleaned promptly.

Related: Monomer, Personal Protective Equipment
Pedicure Basin Disinfection

The procedure of draining, cleaning, and disinfecting a foot basin with an EPA-registered product at the labeled dilution and contact time after each client. Residual debris and biofilm in jets and screens are a known source of infection if skipped.

Related: Disinfection, Contact Time
Client Record

A written or electronic file documenting each service, products used, health information, consent, and any adverse reactions. Accurate records support continuity of care and are required for demonstrating compliance during inspections.
