OH Nail Technician key terms

A microorganism that can cause disease, including bacteria, viruses, fungi, and parasites. In salons, pathogens may live on skin, nails, hands, tools, linens, and surfaces, so consistent infection control matters.

A disease-causing microorganism carried in blood or other body fluids, such as hepatitis B, hepatitis C, and HIV. Technicians prevent transmission with gloves, careful handling of sharp tools, and proper cleanup of blood.

Infection-control practices used with every client no matter what their health status appears to be, including hand hygiene, gloves, and safe handling of blood and body fluids. Treating everyone the same reduces risk.

Barrier items worn to keep infectious material off the technician, such as disposable gloves, goggles, masks, and aprons. Gloves are changed between clients and are never washed and reused.

A specific event in which blood or other potentially infectious material contacts broken skin, mucous membranes, or eyes, or enters through a cut or needlestick. It should be reported and handled under the salon's exposure plan.

A standardized document supplied with a chemical product that lists its hazards, safe handling, first aid, and storage requirements. Keep one accessible for every product in the salon.

Cleaning with soap or detergent and water to remove visible dirt, oil, and debris from tools, hands, and surfaces. Sanitation lowers the number of germs but does not kill them, so disinfection normally follows.

Using an EPA-registered product at the labeled dilution and contact time to destroy most disease-causing organisms on nonporous tools and surfaces. It does not destroy spores; that requires sterilization.

A process that destroys all microbial life, including bacterial spores, on implements, typically using an autoclave, dry heat, or chemical sterilant. It is reserved for items that may contact broken skin or blood.

A device that uses high-pressure steam to sterilize metal implements. Items must be cleaned and dried first, then processed, pouched, dated, and stored so they stay sterile until use.

A product approved by the U.S. Environmental Protection Agency for killing germs on objects, carrying a registration number plus directions for dilution and contact time. Follow the label exactly, since incorrect use may not disinfect.

The number of minutes a tool or surface must remain wet with disinfectant for the product to work as labeled. Cutting it short lets germs survive, so implements stay fully submerged or thoroughly wet.

A product made to be used once on one client and then discarded, such as paper files, wooden sticks, cotton, and disposable liners. These cannot be disinfected and must never be reused.

The hard, visible covering of keratin that sits on the fingertip or toe tip and protects the nail bed. It is produced by the matrix and grows forward as new cells harden.

The pink tissue directly beneath the nail plate, supplied with nerves and blood vessels. It appears pink because blood shows through the translucent plate, and it supports nail growth.

The growing region at the base of the nail where new nail cells are produced and pushed forward. Located under the proximal nail fold, it determines the nail's thickness and shape.

The pale half-moon visible at the base of the nail plate, where the matrix is thickest. It is living nail structure, not cuticle, and should never be scraped, cut, or aggressively pushed.

The living skin fold at the base of the nail plate that seals the nail against infection. It is often mistaken for the cuticle and should not be cut away, though gentle pushing is acceptable.

The thin layer of dead tissue attached to the nail plate at the base of the nail. Unlike the living eponychium, it may be gently loosened and removed during a manicure service.

The tough protein that forms nail plates, hair, and the outer layer of skin. Its structure and the nail's moisture level determine how hard or flexible a nail is.

A fungal infection of the nail that may cause thickening, yellow-brown discoloration, and crumbling at the free edge. It must be diagnosed and treated by a physician, so refer the client and do not apply enhancements.

Redness, swelling, and pain in the skin around the nail, sometimes with pus, often following torn cuticles, hangnails, or aggressive cuticle work. Refer the client for medical care and never squeeze or drain the area.

A contagious fungal infection of the feet that causes itching, peeling, and redness, especially between the toes. Do not perform a pedicure on affected skin; refer the client and disinfect all tools and the basin.

A service that shapes, cleans, and conditions the natural fingernails and hands, often including soaking, filing, cuticle care, massage, and polish. Sanitation and careful tool use are required throughout.

A service for the feet and toenails that includes soaking, exfoliation, nail shaping, cuticle care, massage, and polish. Because feet carry more bacteria and fungi, basin cleaning and tool disinfection are essential.

The thin first layer of polish that protects the nail plate, boosts adhesion, and helps prevent staining from colored polish. Apply it evenly and cap the free edge to slow chipping.

The final polish layer that seals in color, adds shine, and reduces chipping and smudging. Some top coats cure under a UV or LED lamp, while others simply air dry.

The liquid part of a liquid-and-powder acrylic system that reacts with polymer powder to create a hard nail coating. It has a strong odor, so use ventilation and avoid skin contact.

The powder part of an acrylic system, made of fine plastic particles that combine with monomer liquid to harden. The mixing ratio affects strength, set time, and how well the product adheres.

A nail enhancement product that hardens only when cured under an ultraviolet or LED lamp. It must be fully cured and later removed by soaking or gentle filing rather than by force.

A discussion before the service covering the client's goals, health history, medications, allergies, and past nail services, plus an explanation of what will be done. It builds trust and prevents avoidable problems.

A client's clear agreement to a service after being told the steps, products, possible risks, and alternatives. Documenting it protects both the client and the technician and reflects ethical practice.

Any condition that makes a service unsafe or unwise, such as an open sore, fungal infection, or known product allergy. Recognize it during consultation and either decline the service or modify the plan.

Directing a client to a physician, dermatologist, or podiatrist when a condition is beyond the technician's legal scope, such as infection or unexplained nail changes. Note the referral in the client's record.

Keeping a client's personal and health information private and sharing it only with permission or when the law requires. Discussing clients outside the professional relationship is unethical and can be illegal.

The state agency that licenses and regulates cosmetologists, barbers, nail technicians, estheticians, and salons in Ohio and enforces the related statutes and administrative rules.

The body of rules adopted by Ohio agencies, including the cosmetology and barbering rules covering licensing, sanitation, and salon operation. Rules explain how the state statutes are carried out in practice.

The recurring process of keeping a license active by submitting required information, fees, and continuing education before the expiration date. Renewing late may add fees or require reinstatement steps.

Approved courses completed during a license period to keep skills and knowledge current and to meet Ohio renewal requirements. Keep certificates on file in case of an audit or inspection.
