LA Nail Technician key terms

Any organism, such as a bacterium, virus, fungus, or parasite, that can cause disease in people. In the salon, pathogens are the reason hands, tools, and surfaces must be cleaned and disinfected.

A disease-causing microorganism carried in blood or other body fluids, such as hepatitis B, hepatitis C, or HIV. It can enter the body through a cut, nick, or needlestick during nail services.

Infection-control practices that treat all blood and body fluids as possibly infectious. They include hand washing, gloves, and safe handling of sharp tools, and they apply to every client without exception.

A specific event in which a technician's skin, eyes, or mucous membranes contact blood or other potentially infectious material, such as a cut from contaminated nippers. It requires immediate washing and reporting.

The complete destruction of all microorganisms, including bacterial spores, on an object. It is usually achieved with an autoclave and is required for items that penetrate skin or contact broken tissue.

The process of destroying most harmful microorganisms on hard, nonporous surfaces and implements using an EPA-registered product that is mixed and used exactly as the label directs.

A product approved by the U.S. Environmental Protection Agency to kill a broad range of germs on environmental surfaces. Salons must use it on implements and must follow the label's contact time.

A tool made of a material that absorbs liquid, such as wood, paper, foam, or unsealed terry cloth. Porous items cannot be properly disinfected and must be discarded after a single use.

A standardized document supplied by a chemical manufacturer that lists hazards, safe handling, first-aid measures, and storage requirements for a product such as acrylic liquid or disinfectant.

A number showing how coarse or fine the abrasive surface of a file is, with lower numbers being coarser. Grit choice affects how quickly product is shaped and how much natural nail is removed.

A metal or wood tool used to gently push back the nonliving cuticle tissue from the nail plate during a manicure. It must be cleaned and disinfected between clients.

A thin first layer of polish applied to the natural nail to improve adhesion and help prevent staining. It does not replace proper preparation and cleansing of the nail plate.

The final layer of polish that adds shine and seals the color underneath to slow chipping. Some top coats must be cured under a UV or LED lamp to harden.

The liquid part of a two-part acrylic system, typically an ethyl methacrylate mixture. It reacts with polymer powder to form a workable bead that hardens into the nail enhancement.

The powder part of an acrylic system, made of finely ground polymer granules containing initiators. Mixed with monomer liquid, it forms a bead that cures into a hard surface.

A liquid applied to the natural nail before acrylic to improve adhesion by preparing the plate surface. It is used sparingly, and the nail must first be free of dust and oils.

The thickest point of an enhancement, placed over the area where the nail bends most under pressure. Building a correct apex adds strength and reduces breakage.

A light-cured enhancement product, usually a resin kept in a pot or bottle, that stays workable until placed under a UV or LED lamp. Lamp exposure sets it into a hard, glossy surface.

The tacky, oily film left on some cured gels because oxygen in the air blocked full hardening at the surface. It is removed with a clean wipe and the proper cleanser.

A fabric, fiberglass, or silk overlay glued over the natural nail to add strength or repair a crack. These thin materials are sealed with resin or glue to hold them in place.

The visible, hard part of the nail, made mostly of keratin, that rests on the nail bed. Its thickness, condition, and surface shape guide how products are prepared and applied.

The living tissue at the base of the nail where new nail cells are produced. Injury or infection here can permanently change the way the nail plate grows.

The skin lying directly beneath the nail plate, containing blood vessels and nerves. It supplies the plate with nutrients and is sensitive to pressure and injury.

The living fold of skin at the base of the nail plate that seals the gap between skin and nail. It should never be cut; only the nonliving cuticle tissue is removed.

The layer of skin just beneath the free edge of the nail plate, where the nail separates from the fingertip. It helps keep bacteria from entering under the nail.

The pale, half-moon-shaped area at the base of the nail plate that shows through the nail. It is lighter because the tissue there is thicker and overlies part of the matrix.

The painless separation of the nail plate from the nail bed, which leaves a whitish or discolored area as the gap widens. It can follow trauma, product lifting, or fungal infection.

Inflammation of the skin around the nail that causes redness, swelling, and tenderness and may produce pus. It can follow cuticle damage, hangnails, or an untreated infection.

A fungal infection of the nail that thickens, discolors, and crumbles the plate, usually beginning at the free edge. It is contagious and must be referred to a physician.

A bacterial condition in which Pseudomonas grows in the warm, moist space under a lifted enhancement, staining the nail green to black. The product is removed and the client is referred.

Brittle nails that split or break along the length of the nail plate, often caused by dryness, harsh chemicals, or repeated acrylic and gel wear. Care focuses on conditioning, not stronger product.

The state agency that licenses and regulates cosmetologists, nail technicians, salons, and schools in Louisiana, adopts rules, and investigates complaints. Its requirements apply to every licensee working in the state.

The services and procedures a licensed nail technician is legally allowed to perform. Working outside it, such as diagnosing a disease or treating a medical condition, is prohibited.

A credential issued by the state board that allows a person to legally perform nail services, usually after meeting training, examination, and age requirements and paying the required fee.

Training hours a licensee completes within a set period in order to renew a license and stay current. The board sets the number of hours, approved subjects, and documentation requirements.

Written requirements adopted by the state board that explain how the licensing law is applied in practice, covering sanitation, salons, and conduct. Violations can lead to fines or license discipline.

Permission a client gives after being told the risks, benefits, and alternatives of a service. It should be obtained before starting, especially when allergies or nail damage are present.

A condition or circumstance that makes a service unsafe or inadvisable, such as an open sore, infection, or unexplained nail discoloration. The technician should not proceed and may refer the client.

A confidential form on which the technician records service dates, products used, nail and skin observations, and any reactions. It supports consistent service and helps trace problems later.
