Related: Board of Barbering and Cosmetology, Continuing Education
Continuing Education

Approved coursework or training hours a licensee completes within a renewal cycle to maintain licensure. Content typically covers safety, sanitation, and updated rules; records must be kept as proof.

Related: License Renewal
Scope of Practice

The specific services a licensed nail technician is legally permitted to perform, such as manicures, pedicures, and nail enhancements. Performing services outside that boundary, like certain skin or hair treatments, is prohibited.

Related: Salon License, Scope of Practice
Sanitation Standards

The legally required cleaning and disinfection procedures a salon must follow, including tool care, handwashing, and surface maintenance. Inspectors may check compliance, and violations can lead to fines or license action.

Client Record

Documentation kept for each client that notes services performed, products used, and any reactions or skin conditions observed. Records support safety follow-up and may be required during inspections or complaints.

Related: Contraindication, Patch Test
Infection

The invasion of body tissue by disease-causing microorganisms that multiply and produce symptoms. In nail care, infections can enter through small cuts or separated cuticles and may be bacterial, viral, or fungal.

Related: Pathogen, Contraindication
Pathogen

Any microorganism capable of causing disease, including certain bacteria, viruses, fungi, and parasites. Nail technicians must assume blood and body fluids can carry pathogens and use standard precautions.

Related: Infection, Standard Precautions
Standard Precautions

A set of infection-control practices applied to every client regardless of known health status, including hand hygiene, gloves, and safe handling of sharp or contaminated items. They reduce transmission of bloodborne and other pathogens.

Related: Hand Hygiene, Personal Protective Equipment
Hand Hygiene

Cleaning hands with soap and water or an alcohol-based sanitizer at key moments, such as before and after each client and after removing gloves. It is the single most effective routine step in preventing cross-contamination.

Related: Standard Precautions, Cross-Contamination
Personal Protective Equipment

Barriers worn to protect the technician and client, such as disposable gloves, eye protection, and aprons. Gloves are single-use, changed between clients, and never washed or reused.

Related: Standard Precautions, Hand Hygiene
Cross-Contamination

The transfer of microorganisms from one person, tool, or surface to another. Using dirty implements, sharing product containers, or touching clean items with contaminated gloves spreads infection.

Related: Hand Hygiene, Disinfection
Cleaning

The physical removal of visible debris, oils, and residue from tools or surfaces using soap, detergent, or an ultrasonic unit. Cleaning must happen before any disinfection step because soil blocks disinfectants.

Related: Disinfection, Sterilization
Disinfection

Using a chemical agent registered for that purpose to destroy most pathogenic microorganisms on nonporous implements and surfaces. Tools must be cleaned first, then fully immersed for the contact time on the label.

Related: Cleaning, Sterilization, EPA-Registered Disinfectant
Sterilization

A process that destroys all microbial life, including bacterial spores, usually through heat, steam, or chemical sterilants. It is required for items that may contact broken skin or body fluids.

Related: Disinfection, Cleaning
EPA-Registered Disinfectant

A hospital-grade product approved by the Environmental Protection Agency for killing specified organisms on surfaces. The label states the dilution, contact time, and safe handling instructions that must be followed.

Related: Disinfection, Material Safety Data Sheet
Material Safety Data Sheet

A document, now often called a Safety Data Sheet, that describes a product's hazards, safe handling, and first-aid measures. Salons must keep these available for the chemicals they use.

Related: EPA-Registered Disinfectant, Ventilation
Bloodborne Pathogen

A microorganism carried in blood that can cause disease, such as hepatitis B, hepatitis C, and HIV. Nail technicians must avoid contact with blood and follow exposure procedures if a cut occurs.

Related: Standard Precautions, Sharps Disposal
Sharps Disposal

Placing used blades, nippers, or other sharp items in a puncture-resistant, labeled container rather than ordinary trash. Proper disposal protects staff and custodial workers from accidental injury.

Related: Bloodborne Pathogen, Personal Protective Equipment
Porous vs. Nonporous Implements

Porous items, like wooden sticks or unsealed files, absorb liquids and cannot be reliably disinfected, so they are discarded or given to one client. Nonporous metal or glass tools can be cleaned and disinfected.

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

A product or implement intended to be used on one client and then discarded, such as nail files, buffers, or wooden pushers. Reusing such items risks cross-contamination and violates sanitation practice.

Related: Porous vs. Nonporous Implements, Cross-Contamination
Ventilation

The movement of fresh air through a salon to reduce fumes from acrylics, solvents, and disinfectants. Local exhaust or open windows help protect technicians and clients from respiratory irritation.

Related: Material Safety Data Sheet, Allergic Reaction
Ergonomics

Designing work posture, tools, and furniture to reduce strain on the body. Nail technicians use adjustable chairs, good lighting, and neutral wrist positions to prevent repetitive injuries.

Related: Carpal Tunnel Syndrome
Carpal Tunnel Syndrome

A nerve compression disorder causing numbness, tingling, or weakness in the hand and wrist from repetitive motion. Proper posture, breaks, and tool design help reduce risk for nail technicians.

Related: Ergonomics
Allergic Reaction

An immune response to a substance, seen as redness, itching, swelling, or rash. In nail services, reactions to acrylics, adhesives, or polish require stopping the service and referring the client for medical care.

Related: Patch Test, Contraindication
Patch Test

A small trial application of a product, such as adhesive or tint, on a limited area to check for sensitivity before full use. A positive result means the product should not be used.

Related: Allergic Reaction, Client Record
Nail Technology

The licensed practice of caring for and enhancing nails, including manicures, pedicures, sculpting, tips, wraps, and polish. It requires knowledge of anatomy, sanitation, and safe product use.

Related: Scope of Practice, Manicure

Nail Plate

The hard, visible keratin layer covering the tip of each finger or toe. It protects the nail bed and its appearance can signal underlying health problems.

Related: Nail Bed, Keratin
Nail Bed

The skin layer directly beneath the nail plate, containing blood vessels and nerves. Injury or separation of the nail plate from the bed can be painful and prone to infection.

Related: Nail Plate, Onycholysis
Cuticle

The thin layer of dead skin at the base of the nail plate that seals the area where the nail emerges. It should be gently pushed back, not cut, to avoid opening a path for infection.

Related: Nail Plate, Paronychia
Keratin

The tough protein that forms the main substance of nails and hair. Its structure gives nails strength and flexibility, and its condition reflects nutrition and health.

Related: Nail Plate
Onycholysis

The painless separation of the nail plate from the nail bed, often from trauma, moisture, or fungal infection. A technician should not apply enhancements over an affected nail and should refer the client.

Related: Nail Bed, Contraindication
Paronychia

Inflammation or infection of the tissue around the nail, causing redness, swelling, and pain. It may follow cuticle damage or ingrown nails and requires medical referral rather than nail service.

Related: Cuticle, Contraindication
Contraindication

A condition or circumstance that makes a service unsafe or inadvisable, such as open wounds, active infection, or severe inflammation. The technician should decline the service and refer the client to a physician.
