Infection Control, Sanitation, and Salon Safety

  • Disinfection kills most microorganisms on nonporous surfaces using an EPA-registered hospital-grade disinfectant mixed at label dilution and left for the full contact time (commonly 10 minutes).

  • Sterilization destroys all microbial life including spores and requires an autoclave; reserve it for implements that can withstand heat and moisture.

  • Classify implements first: nonporous items (metal, glass, hard plastic) can be cleaned and disinfected; porous items (files, buffers, wooden sticks, cotton) cannot be disinfected and must be discarded or given to the client.

  • Cleaning with soap and water must always precede disinfection, because organic debris inactivates disinfectants.

  • UV light cabinets and ultrasonic units are not disinfectants on their own; an ultrasonic cleaner only removes debris before the disinfection step.

  • Blood spill rule: stop the service, don gloves, clean the area, apply an EPA-registered tuberculocidal disinfectant, cover with a bandage, and discard all contaminated porous items.

  • Footbath rule: drain, clean, and disinfect the basin and jets after every client with a hospital-grade product at the labeled contact time.

  • Keep a Safety Data Sheet on site for every chemical, label all secondary containers, and store products away from food, heat, and sunlight.

  • Wash hands with soap and water for at least 20 seconds before and after every client; use hand sanitizer only when hands are not visibly soiled.

Nail and Skin Anatomy, Physiology, and Disorders

  • The nail plate is keratin resting on the nail bed; the matrix at the base produces it, and the lunula is the visible portion of the matrix.

  • The cuticle (eponychium) seals the proximal nail fold and the hyponychium seals beneath the free edge; both are infection barriers and neither should be cut.

  • Growth rate: fingernails about 0.1 mm per day (roughly 1/8 inch per month) with full replacement in 4-6 months; toenails about 1/25 inch per month with replacement in 9-12 months.

  • Growth is faster in summer, in youth, during pregnancy, and on the dominant hand; it is slower in winter, in older adults, and with poor circulation.

  • Transverse grooves (Beau's lines) follow illness or matrix injury, longitudinal ridges increase with age, and pitting suggests psoriasis.

  • Refer rather than treat: onychomycosis, paronychia, pseudomonas (green) discoloration, warts, psoriasis, lichen planus, and any open or oozing lesion.

  • Terminology: onychocryptosis = ingrown nail, onycholysis = plate separating from the bed, onychauxis = thickening, onychorrhexis = splitting, koilonychia = spoon nail.

  • Each hand has 8 carpals, 5 metacarpals, and 14 phalanges; blood arrives via the radial and ulnar arteries and lymph drains to the epitrochlear then axillary nodes.

Manicuring and Pedicuring Services

  • Standard manicure sequence: consult, wash hands, remove old polish, shape with a file, buff, push back cuticle, massage, base coat, two color coats, top coat.

  • File natural nails with 180-240 grit using light strokes from corner toward center; coarse grits (80-100) are only for reducing product.

  • Cuticle work is limited to pushing back softened cuticle; nippers are for dead hangnails or nonliving tissue only, because cutting living tissue is prohibited.

  • Nail shapes: square, squoval, round, oval, almond, stiletto, coffin; the shape must follow the natural free-edge curve and stay clear of the sidewalls.

  • Base coat protects the plate from pigment staining and improves adhesion; top coat seals color and adds gloss; thin coats cure faster than thick coats.

  • Pedicure: soak 5-10 minutes, use a single-use liner, and reduce callus on moistened skin with a file or pumice, never on broken skin or on diabetic feet without clearance.

  • Massage strokes are effleurage (gliding), petrissage (kneading), tapotement (tapping), and vibration; avoid massage over inflammation, swelling, fractures, or contagious lesions.

  • Stop or modify the service for open wounds, contagious infection, severe inflammation, uncontrolled diabetes, recent surgery, or a known product allergy.

Artificial Nail Enhancements (Acrylic, Gel, Wraps, Tips)

  • Acrylic is liquid monomer plus powder polymer; the bead ratio controls cure speed and strength, with too wet causing brittleness and too dry causing weakness and cloudiness.

  • EMA (ethyl methacrylate) is the industry standard monomer; MMA is not FDA-approved for cosmetic nails because it is rigid, hard, and difficult to remove.

  • Prep order: sanitize, push back cuticles, gently remove shine from the plate, dehydrate, then prime; never over-file or groove the natural nail plate.

  • Zones: zone 1 is the free edge, zone 2 is the stress area where the apex belongs, zone 3 is near the cuticle; product should be thin at the cuticle and sidewalls.

  • Tips come in full well, half well, and no-well styles; blend the well seam until invisible, and use forms rather than tips when sculpting an extension.

  • Gel cures only under the correct UV/LED lamp; apply thin even layers, cap the free edge, and wipe the inhibition layer with the manufacturer's cleanser.

  • Wraps of silk, linen, or fiberglass are applied with resin or adhesive over a crack or as an overlay; wrap resin does not deliver the strength of acrylic.

  • Rebalance or fill every 2-3 weeks; remove product with an acetone soak or the manufacturer's solvent and never pry or force an enhancement off.

  • Overexposure signs include redness, swelling, itching, and lifting near the cuticle; remove the product, refer the client to a physician, and switch to a lower-sensitizer system.

Nail Art, Repairs, and Maintenance

  • Layer order for art is base color, then art medium, then top coat; seal thick items and rhinestones inside the product so they cannot catch and lift.

  • Crack repair: clean, dry, and lightly buff the area, then bridge it with silk or fiberglass wrap and resin or a thin acrylic patch; a broken free edge also needs the stress area rebuilt.

  • A split natural nail can be stabilized temporarily with a tea-bag or silk patch and polish, then scheduled for a follow-up visit.

  • Airbrush, stamping, water decals, foils, marbling, and ombre all require a fully cured base; wet-on-wet art must be sealed within one working layer to avoid smearing.

  • Maintenance intervals: fills every 2-3 weeks and pedicures every 4-6 weeks; booking the next visit at checkout protects retention.

  • Aftercare: cuticle oil daily, gloves for wet work and household chemicals, no using the nails as tools, and a file on hand for snags.

  • Repair pricing rule: charge a repair fee when one to three nails are affected; recommend a full rebalance when four or more have lifted or broken.

  • Nail art must never be applied over broken skin or an open lesion; if the plate is damaged, stop the service and refer.

Client Consultation, Communication, and Professional Conduct

  • The intake records allergies, medications, medical conditions, occupation, hobbies, previous product reactions, and the client's service goals.

  • Ask open-ended questions and restate the client's words back to confirm desired shape, length, color, and service before beginning work.

  • Patch test adhesives and acrylics on clients with a history of reaction and wait 24-48 hours before a full application.

  • Do not diagnose: describe what is observed, advise the client to see a physician, and document the referral on the record card.

  • Scope of practice is manicure, pedicure, enhancements, and nail art; it excludes medical treatment, cutting living tissue, and prescribing.

  • Client health information stays confidential and is discussed only where it cannot be overheard by other clients.

  • Conflict resolution: listen without interrupting, restate the concern, offer two concrete options, and document the outcome.

  • Refuse or modify a service when the client has a contagious condition, an open lesion, or is intoxicated; explain the reason and offer to rebook.

Washington State Cosmetology Laws and Rules (RCW 18.16 / WAC 308-20)

  • RCW 18.16 is Washington's statute for cosmetology, barbering, esthetics, and nail technology; WAC 308-20 holds the Department of Licensing rules that implement it.

  • A person must hold a valid license issued by the Washington State Department of Licensing to perform nail technology for compensation.

  • The salon or shop must also be licensed; licenses must be current, posted, and available for inspection at the place of business.

  • Practice is limited to licensed individuals and properly supervised students in an approved school; practicing without a current license is a violation.

  • Unprofessional conduct includes unsanitary practice, intoxication at work, fraud, practicing beyond scope, and aiding unlicensed practice; penalties include fines, suspension, and revocation.

  • Nail technicians may not cut living tissue, use implements that puncture or slice skin, or diagnose and treat disease; suspected disorders must be referred out.

  • Disciplinary actions follow Washington's Administrative Procedure Act, and the licensee is entitled to notice and a hearing.

  • Fees, applications, and renewals are administered by the Department of Licensing; practicing on an expired license is a violation.

Salon Business Practices and Recordkeeping

  • Client record card minimum: name, contact, date, service performed, products used, patch test results, allergies, observations, and the technician's initials.

  • Keep a Safety Data Sheet for every product on hand and review it before introducing a new chemical into the salon.

  • Inventory: rotate first-in, first-out, date containers when opened, store away from sunlight and heat, and never use expired or separated product.

  • Price a service as materials plus labor plus overhead plus profit, and track cost per service so a small product load on a large ticket stays visible.

  • Record daily receipts, deposits, and expenses, reconcile cash and card totals at close, and retain records for tax and audit purposes.

  • Booth renters pay a fixed rent and generally set their own prices and hours, while employees are paid wages or commission under the salon's schedule and control.

  • Carry general and professional liability insurance and confirm the policy covers chemical and allergic reactions.

  • Washington requires a business license with a UBI number and, where applicable, a reseller permit and local endorsements.
