Sanitation and Infection Control

  • Montana rule: implements that contact skin or nails must be cleaned and then disinfected with an EPA-registered hospital-grade disinfectant labeled for the required contact time; single-use items (emery boards, orangewood sticks, cotton, toe separators) are discarded after one client.

  • Disinfection differs from sterilization: disinfection destroys most pathogenic organisms on inanimate surfaces, sterilization destroys all microbial life including spores and is not required for standard nail implements.

  • Two-step procedure after each client: (1) wash implements with soap and water and scrub debris from crevices, (2) fully immerse in disinfectant for the label contact time; disinfectant must be changed per manufacturer instructions or when visibly soiled.

  • Hand washing: wet hands, apply soap, scrub palms, backs, between fingers, and under nails for at least 20 seconds, rinse, dry with a disposable towel; alcohol-based sanitizer is not a substitute when hands are visibly soiled.

  • Blood and body fluid exposure: stop service, put on gloves, clean the area with an EPA-registered tuberculocidal disinfectant, and dispose of contaminated materials in a sealed bag; Montana requires reporting exposure incidents per shop policy.

  • Client screening decision rule: refuse service and refer to a physician when the nail or surrounding skin shows pus, redness, swelling, fever, or a suspected fungal or bacterial infection; do not treat, do not apply product over the site.

  • Pedicure basin rule: after each client, drain, scrub the basin with soap and water, then circulate or fill with an EPA-registered disinfectant for the labeled contact time; removable jet filters are cleaned and disinfected the same way.

  • Tool storage: clean, disinfected implements are stored in a closed, labeled container separate from soiled implements; drawers and containers are cleaned and disinfected at least weekly.

  • Montana shops must have a hand-washing sink with hot and cold running water accessible in the work area; a bathroom sink does not satisfy this requirement.

Nail Anatomy and Disorders

  • Nail plate is composed mainly of keratin; the nail bed lies beneath it and attaches via the bed epithelium. The nail matrix, hidden under the proximal nail fold, produces the plate - matrix damage causes permanent deformity.

  • Nail growth: fingernails average about 3 mm (roughly 1/8 inch) per month and replace in 4–6 months; toenails grow about 1 mm per month and replace in 9–12 months, slower in winter and with poor circulation.

  • Cuticle (eponychium) seals the space between the nail plate and the proximal nail fold; the hyponychium seals under the free edge; the lunula is the visible portion of the matrix and is whitish.

  • Nail plate thickness averages about 0.5 mm on the fingers; the free edge is the portion extending past the hyponychium and has no nerve or blood supply.

  • Onychomycosis (tinea unguium): fungal infection causing thickened, discolored, crumbling nails; service is contraindicated and the client is referred to a physician.

  • Paronychia: bacterial or yeast infection of the tissue around the nail, with redness, swelling, and pus; do not massage or apply product, refer out.

  • Onycholysis: separation of the nail plate from the bed, often from trauma, aggressive filing, or product lifting; do not force product under the lifted area.

  • Beau's lines are transverse grooves from interrupted matrix growth (illness, trauma); koilonychia is spoon-shaped nails; both are documented, not treated, by the technician.

  • Pterygium (nail) is forward growth of the cuticle adhering to the plate; do not cut living tissue - soften with cuticle cream and push back gently.

Manicuring and Pedicuring

  • Manicure sequence: sanitize hands, inspect nails and skin, shape with file in one direction on natural nails, buff, soak or soften cuticles, gently push back, massage, then polish or apply product.

  • File grit rule: lower numbers are coarser (100 is coarser than 240); use 180-grit or finer on natural nails, reserve 100–150 for product removal and artificial nails, and never use a coarse file on the natural plate.

  • Shape decision rule: square and squoval suit strong, wide nail beds; oval and almond suit narrow beds and short nails; point weakens the free edge and is not recommended for active clients.

  • Cuticle nippers are used only on dead, hanging skin (a hangnail) - never to cut the living eponychium, which risks infection and permanent ridge formation.

  • Pedicure sequence: sanitize feet, inspect for infection and contraindications, soak, clean under the free edge, file, treat callus with a paddle or pumice (never a credo blade or razor), massage, polish.

  • Contraindication check before pedicure: diabetes, circulatory problems, and neuropathy require physician clearance and extra care with water temperature and abrasion.

  • Massage strokes: effleurage (gliding), petrissage (kneading), tapotement (tapping), friction (circular); massage toward the heart and avoid over joints and inflamed areas.

  • Polish application: thin base coat, two thin color coats, thin top coat; thin coats cure faster and resist chipping better than one heavy coat.

  • Hot oil manicure uses warmed oil to soften cuticles and hydrate skin; temperature is checked on the technician's wrist before the client's hand is immersed.

Nail Tips, Wraps, and Extensions

  • Tip sizing rule: choose a tip that matches the widest part of the natural nail sidewall to sidewall with no gap and no overlap; if between sizes, go larger and file to fit.

  • Tip application: dehydrate the plate, apply adhesive in a thin even line, hold the tip at a 45-degree angle against the free edge, press down, and hold 5–10 seconds; remove air bubbles to prevent lifting.

  • Tip blending: shorten the tip to the desired length, then blend the seam with a medium-grit file and buffer until the transition is smooth and the tip edge is not visible.

  • Silk and fiberglass wraps are applied with a resin/activator system over a base coat; the wrap adds strength but does not lengthen the nail - it reinforces the natural plate or a tip.

  • Wrap removal: soak in acetone-based remover or use the manufacturer's remover, then gently lift the wrap; never pry or rip it off the natural plate.

  • Tip contraindication: do not apply a tip when the free edge is split, the plate is thin or damaged, or the nail bed shows onycholysis; repair the natural nail first.

  • Nail forms are used for sculpting instead of tips; the form is fitted under the free edge and removed after the product sets, so no blending seam is created.

  • Overlay vs. extension: an overlay covers the natural plate only; an extension adds length beyond the free edge using a tip or form plus product.

  • Adhesive safety: cyanoacrylate glues bond skin instantly - keep remover on hand, store upright away from eyes, and never use a glue that has thickened or clogged.

Quick reference

Acrylic Nails

  • Acrylic system is a powder (polymer) and liquid (monomer) mixed to form a bead; the correct ratio is roughly 1.5 parts powder to 1 part liquid by volume - a bead that holds its shape and does not run is correct.

  • Monomer is a skin and respiratory irritant; use in a ventilated area, keep the container closed, and avoid skin contact - overexposure can cause allergic sensitization.

  • Bead placement: place the bead at the stress area (where the free edge meets the nail bed) and press forward and back with the brush; do not flood the cuticle or sidewalls.

  • Product application rule: keep acrylic off the skin and cuticle - product touching skin lifts, and repeated skin contact increases allergy risk.

  • Filing: use a 100–150 grit for shaping product and 180 or finer near the natural plate; over-filing the natural nail causes thinning and sensitivity.

  • Removal: file down the bulk, then soak in acetone or use the manufacturer's remover until soft; never force or pry product off the nail plate.

  • Lifting causes: moisture on the plate, cuticle not removed, product on skin, incorrect mix ratio, or missing stress-area reinforcement.

  • Stress area is the most breakage-prone zone; a slightly thicker application there and a proper apex reduce breakage.

  • Contraindication: do not apply acrylic over infected, inflamed, or broken skin, or over a nail with onycholysis; refer the client for treatment first.

Quick reference

Gel Nails

  • Gel product cures only under UV or LED light; uncured gel left on skin can cause allergic contact dermatitis, so any gel on the skin is removed before curing.

  • Cure-time rule: follow the manufacturer's lamp and time for the specific gel line - mixing brands or lamps can undercure and cause lifting or allergy.

  • Gel polish application: base coat, cure, thin color coats, cure each, top coat, cure, then cleanse the inhibition layer with the manufacturer's cleanser if required.

  • Gel is more flexible than acrylic and is applied in thin layers; thick layers trap uncured product and cause heat spikes or lifting.

  • Removal: file the top coat, wrap with acetone-soaked cotton and foil (or use the manufacturer's remover), wait the labeled time, then gently push off softened gel; never scrape hard.

  • LED lamps cure faster than UV lamps for compatible gels; UV lamps require longer times and the bulbs degrade - replace per manufacturer schedule.

  • Contraindication: gel should not be applied over infected or broken skin; clients with known acrylate allergy should be referred to a physician before gel service.

  • Gel over natural nail is an overlay; gel over a tip or form is an extension - the same application and cure rules apply.

  • Inhibition layer is the tacky uncured surface after curing; it is removed with cleanser before the next layer or final finish, depending on the system.

Nail Art and Design

  • Design planning rule: decide the design, colors, and placement before starting so the product does not set while the technician is still deciding.

  • Color theory: complementary colors (opposite on the color wheel) create contrast; analogous colors (adjacent) create harmony; use contrast for accent nails.

  • Nail art media: polish, gel, acrylic, airbrush, stamping, foils, rhinestones, and hand-painting - each has its own cure or adhesive requirement.

  • Stamping and decals must be sealed under a top coat so edges do not lift; rhinestones are set in wet product or adhesive and then sealed around the base.

  • French manicure: white free edge with a natural or pink base; the smile line should follow the natural free edge and be consistent across all ten nails.

  • Airbrush uses thinned paint and a stencil; keep the airbrush tool clean and the work area ventilated, and mask the surrounding skin.

  • Sanitation rule for art: shared brushes, dotting tools, and stampers are cleaned and disinfected between clients; porous items that cannot be disinfected are single-use.

  • Design must fit the client's nail shape and lifestyle: long, elaborate art on a short active nail bed chips faster and is harder to maintain.

  • Color choice rule: warm skin tones generally suit warm colors (reds, oranges, yellows) and cool tones suit cool colors (blues, greens, purples); verify with the client before applying.

Client Consultation and Communication

  • Consultation sequence: greet, review the client's history and preferences, inspect nails and skin, identify contraindications, agree on the service and price, then proceed.

  • Health history questions: allergies (especially acrylates and adhesives), medications, diabetes, circulatory problems, skin or nail infections, and pregnancy - all affect product choice and service safety.

  • Contraindication decision rule: if the client reports or shows signs of infection, broken skin, or an allergic reaction, decline the service and refer to a physician; document the referral.

  • Informed consent: explain the products, the process, the risks (lifting, allergy, damage from improper removal), and the aftercare before the service begins.

  • Communication rule: use plain language, avoid diagnosing, and never promise a medical outcome - the technician describes what is observed and refers.

  • Aftercare instructions: keep nails dry for the first hours, use cuticle oil, wear gloves for household chemicals, and return for professional removal rather than prying product off.

  • Conflict handling: listen, restate the client's concern, offer a concrete remedy within shop policy, and document the resolution; do not argue in front of other clients.

  • Documentation: record the service, products used, and any reaction in the client's record so future services and any follow-up are informed.

Professional Ethics and Business Practices

  • Scope of practice: a nail technician cleans, shapes, and beautifies nails and applies product; diagnosing disease, treating infection, and using credo blades or razor callus removal are outside the scope.

  • Confidentiality: client health information and records are kept private and shared only as required by law or with the client's consent.

  • Pricing and disclosure: quote the full price and any add-ons before the service; hidden charges and bait-and-switch pricing are unethical and may violate Montana consumer protection law.

  • Record keeping: retain client records and service documentation per Montana Board of Cosmetology requirements and shop policy; records support defense against complaints.

  • Insurance and licensing: maintain a current license displayed at the workstation and carry the liability coverage required by the shop; practicing on an expired license is prohibited.

  • Advertising rule: never claim medical benefits, cures, or guaranteed results; advertising must be truthful and must not misrepresent licensure or training.

  • Sanitation ethics: refusing to cut corners on disinfection protects clients and the license - shortcuts are grounds for discipline by the Board.

  • Conflict of interest: do not sell products you are not trained to use or recommend services the client does not need; disclose any incentive you receive.

  • Continuing education: Montana requires license renewal with continuing education hours per the Board's current rule; keep certificates on file.

Quick reference

Montana Laws and Regulations

  • Nail technicians in Montana are licensed by the Montana Board of Barbers and Cosmetologists under the Department of Labor and Industry; a license is required to perform services for compensation.

  • License renewal: Montana licenses renew on a set cycle with continuing education and fee requirements - verify the current cycle and hour count on the Board's website before renewal.

  • Shop sanitation rules: shops must have a hand-washing sink, hot and cold running water, an EPA-registered disinfectant, closed storage for clean implements, and separate containers for soiled items.

  • Implements that contact skin or nails must be cleaned and disinfected after each client; single-use items must be discarded and not reused.

  • The Board may discipline a licensee for unsanitary practices, practicing outside scope, fraud, or practicing on a lapsed license; discipline can include fine, suspension, or revocation.

  • Display rule: the license must be displayed in the shop and available for inspection by the Board or its agents.

  • Client records and sanitation logs must be maintained and available for inspection during business hours.

  • Montana prohibits unlicensed practice; a technician may not allow an unlicensed person to perform services in the shop.

  • Rule changes: the Board updates sanitation and licensing rules periodically - the current Montana Administrative Rules and Board website are the authoritative source.
