32 cards. Read the term and the definition here. The deck at the top of this page is optional.

Sanitation vs. disinfection

Sanitation physically removes soil and reduces microbes on surfaces. Disinfection chemically destroys most pathogenic organisms on nonporous implements. Neither process kills bacterial spores, which requires sterilization.

EPA-registered hospital disinfectant

A product labeled to kill specified pathogens on inanimate surfaces. The label states the dilution, contact time, and pathogen claims; the implement must stay submerged for the full contact time.

Standard precautions

The practice of treating all blood and body fluids as potentially infectious regardless of known diagnosis. It requires gloves for contact with body fluids and hand washing before and after every client.

Porous vs. nonporous implements

Porous items absorb liquids and cannot be reliably disinfected, so files, buffers, and wooden sticks are single use. Nonporous metal implements can be cleaned and chemically disinfected or sterilized.

Nail matrix function

The matrix is the tissue at the proximal nail fold that produces the nail plate. Damage to the matrix causes permanent nail deformity, so tools must never be forced into the proximal fold.

Eponychium vs. cuticle

The eponychium is living skin at the base of the nail plate. The cuticle is dead tissue on the plate surface. Only the cuticle may be lightly trimmed; cutting the eponychium risks infection.

Nail growth rate

Fingernails grow about 3 mm per month and toenails about 1 mm per month. A fingernail fully replaces in roughly four to six months, slower in winter and faster in summer.

Hyponychium

The seal of skin between the free edge of the nail plate and the fingertip. It limits entry of debris and microbes under the plate; aggressive cleaning under the free edge can break this seal.

Onychomycosis

A fungal nail infection causing thickened, discolored, crumbly nails with debris under the plate. It is contagious and outside salon scope; the client must be referred to a physician.

Paronychia

Inflammation or infection of the tissue around the nail, often bacterial, with redness, swelling, and pain. Active paronychia is a contraindication to service and requires medical referral.

Pseudomonas discoloration

A green-black discoloration caused by bacterial growth between the nail plate and bed, often after lifting or moisture trapping. It is an infection, not a stain, and needs referral.

Beau's lines

Transverse grooves across the nail plate caused by a temporary interruption of matrix growth after illness, trauma, or severe stress. They grow out and are not treated in the salon.

Onycholysis

Separation of the nail plate from the nail bed, often from trauma or aggressive filing. Product and tools must not be forced into the separated area, and the cause should be evaluated.

Natural nail filing direction

File natural nails with a fine-grit file using one-direction strokes from corner toward center. Sawing back and forth creates splits and peeling at the free edge.

Pedicure basin sanitation

After each client, drain the basin, clean with detergent, and disinfect with an EPA-registered product for the label contact time. Single-use liners reduce contamination but do not replace disinfection.

Cuticle nipper use

Nippers are reserved for hangnails or loose dead cuticle. Cutting live tissue around the nail fold creates an open wound and increases infection risk; many states limit this practice.

Massage stroke direction

Massage strokes move toward the heart to support venous return. Avoid deep pressure over joints, varicose veins, or inflamed skin, and stop if the client reports pain.

Acrylic polymerization

Liquid monomer mixed with polymer powder cures by an exothermic chemical reaction. The correct bead ratio produces a workable consistency; too much monomer causes shrinkage and heat spike.

Monomer sensitization

Ethyl methacrylate monomer can cause allergic contact dermatitis with repeated skin contact. Technicians should avoid skin exposure, keep containers closed, and use ventilation.

Gel inhibition layer

The tacky uncured surface left on gel after light curing, caused by oxygen inhibiting polymerization. It is wiped with alcohol and is not a sign of a defective product.

Dehydrator and primer

Dehydrator removes surface oils from the natural plate. Primer improves adhesion to keratin; acid-free primer is gentler, and excess primer on skin can cause irritation.

Proper product removal

Soak acrylic or gel in acetone with the nail wrapped and covered until product softens. Never pry or force product off, because that removes layers of the natural plate.

Nail tip sizing

A tip must match the sidewall width exactly. A tip that is too wide puts pressure on the sidewalls and lifts; one that is too narrow leaves a visible ledge.

Blending the tip seam

File and buffer the tip seam until it is flush with the natural plate before applying product. A raised seam traps moisture, shows through product, and causes lifting.

Sculpting form placement

A form sits under the free edge with sidewalls aligned and no gap. Correct placement prevents product from leaking under the form and shapes the free edge.

French manicure smile line

The smile line should follow the natural free edge and stay consistent across all ten nails. Asymmetry and uneven placement are the most visible flaws in a French service.

Informed consent

Explaining the products, risks, expected wear time, and removal process before service, then documenting the client's agreement. It protects both client and technician.

Scope of practice

The legally permitted services a licensed nail technician may perform. Diagnosis and treatment of disease are excluded; suspected disorders are described objectively and referred to a physician.

Objective documentation

Recording observable findings such as redness, swelling, or separation rather than a diagnosis. Objective notes support referral decisions and reduce liability if a claim arises.

Hazard Communication program

An OSHA-required written program covering chemical inventory, labeled containers, accessible safety data sheets, and worker training for products used in the salon.

State board licensure

Each state board sets licensing requirements, scope of practice, sanitation rules, and renewal cycles including continuing education hours. Requirements differ by state and must be verified locally.

Autoclave sterilization

Steam under pressure, typically 121 °C at 15 psi for 15–30 minutes, destroys all microbial life including spores. Items must be cleaned first and monitored with indicators.
