Disinfection

A process using an EPA-registered hospital-grade product to destroy most harmful microorganisms, except bacterial spores, on nonporous implements and surfaces after they are cleaned.

Related: Sterilization, Sanitation, Bloodborne Pathogens
Sanitation

The lowest level of decontamination: scrubbing with soap and water or a detergent to physically remove visible debris, oils, and many microorganisms from surfaces and tools before further processing.

Related: Disinfection, Material Safety Data Sheet
Sterilization

The complete destruction of all microbial life, including bacterial spores, usually achieved with an autoclave using steam under pressure; required only for items that contact broken skin or blood.

Related: Disinfection, Bloodborne Pathogens
Bloodborne Pathogens

Disease-causing microorganisms such as hepatitis B, hepatitis C, and HIV that can be transmitted through contact with blood or other potentially infectious body fluids during nail services.

Related: Standard Precautions, Exposure Incident, Sterilization
Standard Precautions

An infection-control approach treating all blood, body fluids, and non-intact skin as potentially infectious, so gloves and other barriers are used with every client regardless of known health status.

Related: Bloodborne Pathogens, Exposure Incident
Exposure Incident

A specific event in which blood or other potentially infectious material contacts broken skin, mucous membranes, or the eyes, requiring immediate washing and reporting to a supervisor.

Related: Standard Precautions, Bloodborne Pathogens
Material Safety Data Sheet

A manufacturer document summarizing a product's chemical hazards, safe handling, first-aid measures, and storage requirements; it must be kept accessible to employees who work with that product.

Related: Sanitation
Porous vs. Nonporous Implements

Nonporous items such as metal or glass can be cleaned and disinfected for reuse, while porous items such as buffers, wooden sticks, and cotton cannot be disinfected and must be discarded after one client.

Related: Disinfection, Single-Use Item
Single-Use Item

A product or implement designed to be used on one client only and then thrown away, such as a disposable nail file, orangewood stick, or pedicure liner, because it cannot be reliably cleaned and disinfected.

Related: Porous vs. Nonporous Implements
Nail Plate

The visible, hard keratin structure covering the nail bed, produced by the matrix and composed of tightly packed, flattened dead cells that protect the sensitive nail bed beneath.

Related: Nail Matrix, Nail Bed, Free Edge
Nail Matrix

The living tissue at the base of the nail beneath the proximal nail fold where new nail cells are produced; damage here causes permanent grooves, thinning, or loss of the nail plate.

Related: Nail Plate, Lunula, Nail Malformation
Nail Bed

The skin layer directly beneath the nail plate, rich in blood vessels and nerves, which supplies nourishment and appears pink through the translucent plate.

Related: Nail Plate, Onycholysis
Lunula

The whitish, half-moon shape at the base of the nail plate where the matrix is thickest; it is part of the nail plate, not a separate structure.

Related: Nail Matrix
Cuticle

The thin layer of dead tissue extending from the proximal nail fold onto the nail plate; it seals the nail base against infection and should be softened and gently pushed, never cut.

Related: Eponychium, Nail Matrix
Eponychium

The living skin at the base of the nail plate that covers the matrix area; it is often confused with the cuticle and must not be cut because it is living tissue.

Related: Cuticle, Nail Matrix
Hyponychium

The thickened area of skin beneath the free edge of the nail where the nail plate separates from the nail bed; it forms a protective seal against debris and microorganisms.

Related: Free Edge, Onycholysis
Free Edge

The portion of the nail plate that extends beyond the fingertip or toe tip and is filed, shaped, and trimmed during manicuring and pedicuring services.

Related: Hyponychium, Nail Plate
Onychomycosis

A contagious fungal infection of the nail plate marked by thickening, yellow-brown discoloration, and crumbling; it requires medical referral and disqualifies the nail from enhancement services.

Related: Paronychia, Contraindication
Paronychia

An inflammation or bacterial infection of the tissue surrounding the nail, producing redness, swelling, and pus; it is a contraindication for cuticle work and nail enhancements.

Related: Onychomycosis, Contraindication
Onycholysis

A painless separation of the nail plate from the nail bed caused by trauma, aggressive filing, or infection, leaving a white pocket under the free edge that can trap moisture and microorganisms.

Related: Nail Bed, Hyponychium
Contraindication

A condition or circumstance that makes a service unsafe or inadvisable, such as an active infection, open wound, or undiagnosed disorder, requiring the client to be referred to a physician instead.

Related: Onychomycosis, Paronychia, Client Consultation
Nail Malformation

An abnormal shape or growth pattern of the nail, such as a ridge, furrow, or pincer nail, often caused by matrix injury or inherited traits and managed by adapting the service rather than treating it.

Related: Nail Matrix
Contraindication Screening

The step during consultation in which the technician visually inspects hands, feet, and nails and asks about infections, allergies, medications, and prior reactions before beginning any service.

Related: Contraindication, Client Consultation
Nail Plate Filing Direction

The practice of filing from the side of the nail toward the center, or in one direction along each side, to avoid splitting layers and weakening the free edge.

Related: Free Edge, Nail Plate
Pedicure Basin Sanitation

The procedure of draining, cleaning, and disinfecting a foot basin with an EPA-registered hospital-grade product after each client, following the manufacturer's contact time, to prevent cross-contamination.

Related: Disinfection, Single-Use Item
Nail Tip

A pre-shaped plastic extension glued to the free edge of the nail plate to lengthen it before acrylic or gel is applied over the seam for strength.

Related: Nail Wrap, Free Edge
Nail Wrap

A thin fabric, fiberglass, or silk overlay applied with resin over the natural nail or tip to add strength and repair splits without adding significant length.

Related: Nail Tip, Stress Area
Stress Area

The point on an enhanced nail where the free edge meets the nail plate, which bears the most impact and therefore requires extra product thickness and careful shaping.

Related: Nail Wrap, Apex
Monomer

The liquid component of acrylic systems, typically ethyl methacrylate, that softens and binds with polymer powder to form a hard, cured nail enhancement.

Related: Polymer, Liquid-to-Powder Ratio, Product Overexposure
Polymer

The powder component of an acrylic system, made of finely ground plastic particles that absorb monomer liquid and harden into the finished enhancement.

Related: Monomer, Liquid-to-Powder Ratio
Liquid-to-Powder Ratio

The correct balance of monomer to polymer that produces a workable bead; too wet a bead shrinks and weakens, while too dry a bead sets brittle and poorly bonded.

Related: Monomer, Polymer, Apex
Apex

The highest point of the enhancement's upper arch, positioned over the stress area to give strength and a natural profile to the finished nail.

Related: Stress Area, Liquid-to-Powder Ratio
Product Overexposure

An allergic skin reaction to repeated contact with uncured acrylic or gel product, appearing as redness, itching, or blisters; prevention requires gloves and keeping product off the skin.

Related: Monomer, Photoinitiator
Photoinitiator

A compound in UV and LED gels that absorbs light energy and triggers the curing reaction that hardens the gel into a solid film.

Related: UV Gel, Cure Time, Product Overexposure
UV Gel

A light-cured enhancement product applied in thin layers and hardened under a UV or LED lamp; it does not cure in air and must be kept away from daylight during application.

Related: Photoinitiator, Cure Time
Cure Time

The manufacturer-specified number of seconds or minutes a gel or light-cured product must remain under the lamp to fully harden; undercuring causes peeling, dullness, and allergic reaction risk.

Related: UV Gel, Photoinitiator
Informed Consent

A client's agreement to a service after being told the procedure, expected outcome, possible risks such as lifting or allergic reaction, and aftercare requirements in understandable terms.

Related: Client Consultation, Contraindication Screening
