MT Nail Technician key terms

The use of a chemical product registered by the EPA to destroy most pathogenic microorganisms on hard, nonporous implements and surfaces, except bacterial spores. It is required for reusable tools after cleaning.

A process that destroys all microbial life, including bacterial spores, usually through an autoclave using steam under pressure. It is the highest level of decontamination and exceeds what disinfection achieves.

A product that reduces the number of bacteria on a surface to a level considered safe by public health standards. It is a lower level of protection than disinfection and is not a substitute for it on implements.

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

An infection-control approach in which every client is treated as potentially infectious and appropriate barriers are used consistently, regardless of known health status or appearance.

A specific event in which a technician's skin, eye, mouth, or mucous membrane contacts blood or other potentially infectious material, such as a cut from contaminated nippers or a splash during service.

Barriers worn to prevent contact with infectious material, including single-use gloves, safety glasses or goggles, and a mask when splashing or dust is likely during nail services.

The visible, hard keratin structure covering the nail bed, extending from the matrix to the free edge. It protects the sensitive nail bed and gives the nail its shape and strength.

The hidden area at the base of the nail where new cells are produced and keratinized. Damage to the matrix can permanently alter the shape or growth of the nail plate.

The opaque, whitish half-moon visible at the base of the nail plate where the matrix shows through. Its appearance varies among individuals and is not a reliable health indicator.

The seal of skin beneath the free edge of the nail where the nail plate separates from the nail bed. It helps block microorganisms from entering the nail bed.

Inflammation or infection of the skin around the nail, often with redness, swelling, and tenderness. A technician should not service inflamed or infected tissue and should refer the client for medical care.

A fungal infection of the nail plate, often causing thickening, discoloration, and separation from the nail bed. It is contagious, so the technician should avoid service and refer the client to a physician.

A condition or circumstance that makes a nail service inadvisable or unsafe, such as an open wound, active infection, or severe skin irritation. The technician should decline or modify service and refer appropriately.

A light, gliding massage stroke applied with the palms or fingers in the direction of circulation. It is commonly used at the start and end of a hand or foot massage to warm and relax tissue.

A kneading massage movement that lifts and compresses muscle tissue with the fingers, thumbs, or palms. It is used on the hands and lower legs, avoiding pressure over bony areas or varicose veins.

Lightly removing the shine from the natural nail plate with a fine abrasive or buffer to create a surface that allows product to adhere. Over-filing thins the plate and weakens the enhancement.

The section of an enhancement at the tip of the finger where impact and pressure concentrate. It is built slightly thicker to resist breakage and is often called the apex.

The highest point of the enhancement's upper arch, placed near the stress area to provide strength and a natural profile. Correct placement prevents lifting and breakage at the free edge.

The chemical process in which short monomer molecules link into long chains to form a hardened polymer, as when acrylic liquid and powder or gel products cure into a solid enhancement.

The tacky, uncured film left on the surface of a light-cured gel product after curing. It is removed with cleanser before finishing and is not a sign that the product failed.

A component in light-cured gel products that absorbs specific wavelengths from a UV or LED lamp and starts the curing reaction. Mismatched lamps and products can cause under-curing.

A liquid applied to the natural nail plate to improve adhesion of acrylic or gel enhancements. Some primers contain methacrylic acid and must be used sparingly and kept off the skin.

A thin layer of product applied between the natural nail and the enhancement to improve adhesion and reduce lifting. It must be applied evenly and cured according to the manufacturer's directions.

The portion of the nail plate that extends beyond the fingertip and is not attached to the nail bed. It is filed and shaped during services and is vulnerable to splitting and breakage.

A thin overlay of fabric, fiberglass, or silk applied with resin over the natural nail to add strength or repair a split. It is lighter than a full tip-and-acrylic extension.

A preformed plastic extension glued to the free edge to add length before overlay product is applied. Tips must be sized, blended, and attached without bubbles or gaps.

The study of how colors relate and combine, including primary, secondary, and complementary colors. Nail technicians use it to choose shades that flatter skin tone and to correct discoloration.

A circular arrangement of hues used to identify complementary, analogous, and contrasting color relationships. It guides design choices and helps neutralize unwanted tones in nail art.

A client's agreement to a service after being told what it involves, its risks, expected results, and alternatives. Documenting consent protects both the client and the technician.

A confidential written or electronic file of a client's contact details, service history, product use, allergies, and consent. It supports continuity of care and is protected health information.

The ethical and legal duty to keep client information private and disclose it only with permission or as required by law. It includes health conditions, contact details, and service records.

The services and activities a licensed nail technician is legally permitted to perform under state law. Working outside that boundary can result in discipline or loss of licensure.

The state regulatory body that licenses and oversees barbers, cosmetologists, estheticians, and nail technicians in Montana and enforces the applicable administrative rules.

Required coursework a licensee completes to renew a license and stay current on safety, technique, and law. Montana sets specific hour and subject requirements for renewal cycles.
