Disinfection

The use of an EPA-registered chemical product to destroy most pathogenic microorganisms on nonporous implements and surfaces, excluding bacterial spores, following proper contact time and concentration.

Related: Sanitation, Sterilization, EPA Registration
Sterilization

A process that destroys all microbial life, including bacterial spores, on an object, typically using an autoclave with steam under pressure or approved chemical sterilants.

Related: Disinfection, Autoclave
Autoclave

A device that uses pressurized steam to sterilize heat-resistant implements and tools, killing all microorganisms including spores when operated at correct temperature, pressure, and time.

Related: Sterilization
EPA Registration

The federal approval number on a disinfectant label indicating the product has been reviewed and registered by the Environmental Protection Agency for its stated claims and uses.

Related: Disinfection, Contact Time
Contact Time

The length of time an EPA-registered disinfectant must remain wet on a surface or tool to achieve its labeled kill claims, as stated on the product label.

Related: EPA Registration, Disinfection
Standard Precautions

Infection control practices treating all blood, body fluids, and potentially infectious materials as if known to be infectious, regardless of a client's apparent health status.

Related: Personal Protective Equipment, Bloodborne Pathogens
Bloodborne Pathogens

Microorganisms such as hepatitis B, hepatitis C, and HIV that are present in blood and can cause disease when transmitted through blood or other potentially infectious materials.

Related: Standard Precautions, Personal Protective Equipment
Personal Protective Equipment

Barriers such as disposable gloves, safety glasses, and masks worn by a nail technician to prevent skin contact with chemicals, blood, and potentially infectious materials.

Related: Standard Precautions, Safety Data Sheet
Onychomycosis

A fungal infection of the nail plate or nail bed, often causing thickening, discoloration, and separation, which is a contraindication for nail services and should be referred to a physician.

Related: Contraindication, Paronychia
Paronychia

Inflammation or infection of the skin around the nail, often red, swollen, and tender, frequently caused by bacteria entering through a cut or damaged cuticle.

Related: Onychomycosis, Cuticle
Contraindication

A condition, skin disorder, or circumstance that makes a nail service unsafe or inadvisable, requiring the technician to decline service or refer the client to a medical professional.

Related: Onychomycosis, Paronychia, Patch Test
Patch Test

A small application of a product, such as a monomer or adhesive, to the client's skin to check for an allergic reaction before a full service is performed.

Related: Contraindication, Allergic Contact Dermatitis
Nail Plate

The visible, hard keratin structure covering the nail bed and protecting the fingertip, composed of layers of compacted, flattened keratinized cells.

Related: Nail Bed, Matrix, Lunula
Nail Bed

The skin layer beneath the nail plate that contains blood vessels and nerves, extending from the lunula to the hyponychium and providing nourishment to the nail plate.

Related: Nail Plate, Hyponychium, Lunula
Matrix

The area at the base of the nail beneath the proximal nail fold where new nail cells are produced, determining the thickness and shape of the nail plate.

Related: Lunula, Nail Plate
Lunula

The whitish, half-moon-shaped area at the base of the nail plate, visible because the underlying matrix is thicker and less transparent in that region.

Related: Matrix, Nail Plate
Cuticle

The thin layer of dead tissue that seals the space between the nail plate and the proximal nail fold, protecting the matrix from infection and debris.

Related: Eponychium, Paronychia
Eponychium

The living skin at the base of the nail plate that extends over the nail matrix, often mistakenly called the cuticle and requiring careful, gentle handling.

Related: Cuticle, Hyponychium
Hyponychium

The thickened layer of skin under the free edge of the nail plate that seals the nail bed from bacteria and dirt, often called the quick.

Related: Nail Bed, Eponychium
Onychodystrophy

Any abnormal development or change in the shape, texture, or appearance of the nail plate, which may be congenital or result from disease, injury, or improper nail services.

Related: Beau's Lines, Onychomycosis
Beau's Lines

Deep horizontal grooves or ridges across the nail plate caused by a temporary interruption of matrix growth, often following illness, injury, or severe stress.

Related: Onychodystrophy, Matrix
Free Edge

The portion of the nail plate that extends beyond the fingertip and is shaped and filed during manicuring, with no underlying nail bed.

Related: Nail Plate, Filing
Nail Primer

A liquid applied to the natural nail plate before acrylic or gel enhancements to remove surface oils and improve adhesion between the product and the nail.

Related: Monomer, Polymer
Monomer

The liquid component of acrylic nail products, typically ethyl methacrylate, that reacts with polymer powder to form a hardened polymer chain during curing.

Related: Polymer, Polymerization, Primer
Polymer

The powder component of acrylic nail enhancements, made of finely ground polymer beads that combine with monomer liquid to create a moldable, hardenable mixture.

Related: Monomer, Polymerization
Polymerization

The chemical reaction in which monomer molecules link together to form long polymer chains, converting a liquid-and-powder mixture into a hard acrylic nail enhancement.

Related: Monomer, Polymer, Exothermic Reaction
Exothermic Reaction

A chemical reaction that releases heat, such as the curing of acrylic or gel products, which can cause a burning sensation if the product is applied too thickly.

Related: Polymerization, Curing
Curing

The hardening process of a gel or acrylic enhancement, achieved by chemical reaction for acrylics or by exposure to ultraviolet or LED light for gels.

Related: UV Lamp, Polymerization, Exothermic Reaction
UV Lamp

A light source emitting ultraviolet radiation used to cure gel nail products, requiring proper bulb maintenance and replacement to ensure full and safe polymerization.

Related: Curing, Gel Polish
Gel Polish

A long-wearing nail coating cured under a UV or LED lamp, formulated with photoinitiators that harden when exposed to the correct wavelength and intensity of light.

Related: UV Lamp, Curing
Overlay

A thin layer of acrylic, gel, or wrap product applied over the natural nail plate to add strength or protect the nail without extending its length.

Related: Nail Wrap, Nail Tip
Nail Wrap

A nail enhancement made by applying a thin fabric or fiber material, such as silk or fiberglass, over the natural nail and sealing it with resin or adhesive.

Related: Overlay, Nail Tip
Nail Tip

A plastic or acetate extension glued to the free edge of the natural nail to lengthen it before being blended and covered with an overlay or acrylic product.
