NV Nail Technician key terms

The invasion of body tissue by disease-causing microorganisms that multiply and produce signs of illness. In the salon, infection risk comes from contaminated tools, hands, linens, and surfaces contacting broken skin.

Microorganisms capable of causing disease, as opposed to harmless or beneficial ones. Nail technicians must assume blood and body fluids can carry them and must never let a client's skin or nail debris contact another client.

The presence of infectious material or foreign matter on a surface, tool, or skin. A tool is contaminated the moment it touches a client, so it must be cleaned and disinfected before reuse on anyone else.

The physical removal of visible debris, oils, and residue from a tool using soap or detergent and water, usually with scrubbing or ultrasonic action. Cleaning must happen before any disinfection step, because residue blocks disinfectant contact.

The use of a product registered with the EPA as a hospital-grade disinfectant, mixed and used exactly per its label, to destroy most microorganisms on pre-cleaned implements. In Nevada, implements must be cleaned and then disinfected after each client.

A process that destroys all microbial life, including bacterial spores, typically through steam autoclave or dry heat. It exceeds the legal minimum for routine nail implements, though some salons offer it as an added service.

A device that sterilizes tools using pressurized steam at high temperature. Items must be cleaned and dried first, pouched properly, and monitored, and the machine requires regular maintenance and spore testing to confirm it works.

A virus or other microorganism transmitted through blood or body fluids, notably hepatitis B, hepatitis C, and HIV. Nail technicians reduce risk with gloves, handwashing, careful nipping technique, and prompt cleanup of any bleeding.

The practice of treating all blood, body fluids, and non-intact skin as potentially infectious regardless of a client's appearance or stated health status. Gloves and hand hygiene apply to every client, every time.

The federal approval that a disinfectant product carries, showing it has been reviewed for efficacy against labeled organisms. Technicians must read the label for dilution, contact time, and the pathogens the product is proven to kill.

The number of minutes a wet disinfectant must remain on an implement to achieve the kill claimed on the label. Shortening it, or letting tools float above the liquid, leaves the tool effectively undisinfected.

The hard, translucent keratin structure covering the nail bed and protecting the sensitive tissue beneath. Its surface is not living tissue, so filing it does not hurt, but over-thinning it can cause weakness and sensitivity.

The pink tissue directly under the nail plate, rich in blood vessels and nerves and attached to the plate by a thin epithelial layer. Separation here creates a pocket where moisture and organisms can collect.

The living tissue at the base of the nail, partly hidden under the proximal nail fold, where new nail cells are produced. Damage or pressure to the matrix can permanently alter the shape or thickness of the growing nail.

The whitish, half-moon area visible at the base of the nail plate, formed by matrix cells that have not yet fully flattened and hardened. Its appearance varies by person and is not a reliable health indicator on its own.

The thin layer of dead skin that seals the base of the nail plate against the proximal nail fold, blocking moisture and organisms. It should be softened and gently pushed, never cut away entirely, because it is a natural barrier.

The skin seal under the free edge where the nail plate leaves the fingertip. It protects the nail bed from debris and infection, and aggressive cleaning under the free edge can break it open.

Painless separation of the nail plate from the nail bed, leaving a white or yellowish gap that moves as the nail grows. It is a condition to refer, not to disguise, and can be worsened by aggressive filing or improper product application.

A fungal infection of the nail plate or bed that causes thickening, discoloration, crumbling, and sometimes separation. It is contagious, so a technician should not service an active infection and should refer the client to a physician.

Inflammation or infection of the tissue around the nail, often showing redness, swelling, and tenderness near the nail fold. It may follow torn cuticles or aggressive nipping, so it is a reason to stop service and refer.

A condition or circumstance in which a service should not be performed, or should be modified, because it could harm the client. Examples include open wounds, active infection, severe nail separation, and unexplained discoloration.

The tough protein that makes up the nail plate and the outer layer of skin. Nail hardness and flexibility depend on keratin structure and moisture content, not on vitamins applied to the surface.

The portion of the nail plate that extends beyond the fingertip and is trimmed or filed to shape. It has no nerve supply, which is why shortening it is painless when done correctly.

A disposable paper or plastic guide fitted under the free edge to build a temporary wall during sculpting. It must sit snugly against the nail with no gaps, or product will run underneath and create a lump.

The area of a nail enhancement where the free edge meets the nail plate, which bears the most bending force. Correct apex and thickness placement here prevents cracking and lifting.

The thickest point of a sculpted nail, located over the stress zone to give strength without bulk elsewhere. A misplaced apex makes the enhancement feel heavy and prone to breakage at the wrong spot.

The liquid component of acrylic systems, usually ethyl methacrylate, that softens and binds the polymer powder into a hard film. It is flammable and a known sensitizer, so it must be kept covered and handled with ventilation.

The powder component of an acrylic system, made of finely milled plastic beads that carry the pigment and initiator. The powder-to-liquid ratio determines working consistency, strength, and cure speed.

The chemical reaction in which monomer molecules link into long chains to form a solid, hard film. In acrylics it is initiated by a catalyst in the powder, and in gels it is triggered by light.

An allergic reaction that develops after repeated skin exposure to a substance, causing redness, itching, and swelling that worsens with each contact. Once sensitized, a technician may be unable to work with that chemistry at all.

A compound in gel products that absorbs light energy and starts the curing reaction. Different photoinitiators respond to different wavelengths, which is why a lamp must match the product's intended range.

The conversion of a gel or acrylic product from a soft, workable state into a hard, stable film. Under-curing leaves tacky, weak product that can harbor moisture and trigger allergic reactions.

The thin, sticky, uncured film left on the surface of a gel after curing because oxygen interferes with the reaction. It is wiped away with cleanser before finishing, and gloves should be worn during that step.

A light unit that emits ultraviolet or near-ultraviolet energy to cure gel products. Bulbs weaken over time, reflectors get dirty, and clients must be positioned so all five fingers cure evenly.

A client's agreement to a service after being told what it involves, the products used, likely results, and known risks. It should be obtained before work begins and documented in the client record.

A written or electronic history of each service, including products used, timing, client preferences, and any reactions or conditions noted. It supports consistency, helps trace problems, and demonstrates professional care.

The set of services and activities a licensed nail technician is legally permitted to perform, defined by state statute and board rules. Working outside it, such as diagnosing disease, is unlicensed practice regardless of intent.

The state agency that licenses cosmetologists, nail technicians, and salons, sets sanitation and practice rules, inspects establishments, and handles complaints and discipline. Its regulations are the operative rules for Nevada licensees.

The legal authorization to practice granted after meeting education, examination, and application requirements. Licenses carry renewal cycles and continuing education or fee obligations, and practicing without one is unlawful.

A document, now commonly called an SDS, supplied by the manufacturer that lists a product's hazards, safe handling, first aid, and storage requirements. Salons must keep these accessible for the chemicals they use.

The movement of fresh air through a workspace to remove vapors, dust, and fumes. Local exhaust at the work table and general room air exchange reduce inhalation exposure to monomers, solvents, and filing dust.

Gloves, eye protection, masks, and aprons worn to reduce contact with chemicals and infectious material. Nitrile gloves are preferred over latex for chemical work, and gloves must be changed between clients.
