Infection Control, Sanitation, and Safety Practices

  • Cleaning removes visible debris with soap and water; disinfection destroys most pathogens on nonporous items; sterilization destroys all microbial life, including spores.

  • Implements must be washed, rinsed, and dried before immersion, because organic debris in the solution inactivates the disinfectant.

  • A salon disinfectant must be EPA-registered with a tuberculocidal claim and must stay in contact with the implement for the full label time (commonly 10 minutes).

  • Porous items that absorb liquid - emery boards, buffer blocks, wooden sticks, cotton - cannot be disinfected and are discarded after one client.

  • Autoclave sterilization: 15 psi at 121 degrees C (250 degrees F) for 15-30 minutes, verified with indicator tape or spore strips.

  • Hand washing with soap and warm running water lasts at least 20 seconds and is required before and after every service and after glove removal.

  • Blood or body fluid exposure: stop the service, don gloves, absorb the spill, clean the area, disinfect with an EPA tuberculocidal product, and double-bag the waste.

  • Common disinfectant families are quaternary ammonium, phenols, and bleach; a fresh 1:10 bleach dilution is used for blood spills.

  • Never double-dip implements; keep clean and contaminated items in separate labeled containers, and keep the disinfectant jar covered and dated.

Nail Structure, Growth, and Recognizable Disorders and Diseases

  • Structure sequence from deepest to surface: matrix produces the nail plate, the plate rests on the nail bed, and the free edge extends past the hyponychium.

  • Fingernails grow about 0.1 mm per day, roughly 3.5 mm (1/8 inch) per month, and are fully replaced in 4-6 months.

  • Toenails grow about 0.05 mm per day, roughly 1.5 mm per month, and are fully replaced in 9-12 months.

  • The nail plate has no nerves or blood vessels; the nail bed is vascular and sensitive, so pressure or trauma to the bed causes pain.

  • Landmarks: lunula is the visible matrix, eponychium is living proximal skin, cuticle is dead tissue on the plate, hyponychium seals the free edge.

  • The nail plate is roughly 15-18% water at about pH 5.5; repeated wet-dry cycling causes brittleness and splitting.

  • Disorders that do not require referral: Beau's lines, leukonychia, onychorrhexis, onychauxis, onychophagy, and hangnails.

  • Contagious or medical conditions that block service: onychomycosis, paronychia, tinea pedis, Pseudomonas (green) infection, and verruca from HPV.

  • Refusal rule: redness, swelling, pus, heat, broken skin, or discoloration with plate separation means no service and a referral to a physician.

Manicuring and Pedicuring Services

  • Service sequence: consultation, hand washing, set-up, shaping, soak, cuticle care, massage, polish, clean-up, and disinfection.

  • File natural nails in one direction with a fine-grit abrasive (240 or higher); sawing back and forth creates splits and peeling.

  • Apply cuticle softener, push back with a rubber-tipped pusher, and trim only loose non-living tissue; living eponychium is never cut.

  • Pedicure toenails are cut straight across with only slight rounding at the corners to reduce ingrown risk; callus is reduced with a paddle or rasp, not a blade.

  • The foot basin and whirlpool jets are drained, scrubbed, and disinfected with an EPA hospital-grade product for the full contact time between clients.

  • Paraffin is heated to about 125-130 degrees F (52-54 degrees C) and tested on the technician's wrist before application.

  • Massage strokes: effleurage glides, petrissage kneads, tapotement percusses; strokes move from insertion toward origin.

  • Polish sequence: base coat, two thin color coats, top coat, with the free edge capped and 2-3 minutes between coats.

Artificial Nail Products, Application, and Maintenance

  • The acrylic system is liquid monomer plus powder polymer; benzoyl peroxide in the powder initiates polymerization as the product sets.

  • An accurate liquid-to-powder ratio prevents shrinkage, lifting, and bubbles; product that is too wet cures weak and separates from the plate.

  • Prep order: sanitize, push cuticles, remove shine with a fine buffer, dehydrate and prime, apply tip or form, then apply product.

  • Fills are scheduled every 2-3 weeks; any product that has separated at the sidewall or cuticle is removed before rebuilding.

  • Gel systems cure only under UV/LED light of the correct wavelength; the tacky inhibition layer is wiped off with cleanser before finishing.

  • Removal means filing the seal, soaking in acetone for 20-30 minutes, then gently easing product off; product is never pried or ripped from the plate.

  • Monomer vapor is a skin and respiratory sensitizer: keep containers capped, ventilate the area, avoid skin contact, and store away from heat and sunlight.

  • Over-filing thins the natural plate and leads to onycholysis, heat spike, and sensitivity; a thin, even layer of product protects the plate.

Client Consultation, Communication, and Professional Practices

  • The intake form captures medical history, medications, allergies (acrylates, nickel, latex, formaldehyde), pregnancy, and prior nail services.

  • Scope of practice rule: a nail technician may observe and describe a condition but may not diagnose or treat it.

  • Patch test a new monomer, adhesive, or tint 24-48 hours before the first full application for clients with a reactive history.

  • Refuse and refer for open lesions, suspected infection, active allergic reaction, or circulatory complications that make service unsafe.

  • Confidentiality: client records and health information are shared only with the client and, where required, the board or a physician.

  • Document date, products and lot numbers, service performed, any reaction, and the client's signed consent on the record card.

  • Communication technique: open-ended questions, paraphrasing the client's goal, and confirming the plan before starting the service.

Minnesota Statutes, Board Rules, and Licensing Requirements

  • Minnesota Statutes chapter 155A governs licensure of cosmetologists, estheticians, nail technicians, instructors, and salons.

  • Minnesota Rules chapter 2105 contains the facility, equipment, and sanitation standards enforced for licensed salons and technicians.

  • The Minnesota Board of Cosmetologist Examiners issues and renews individual and salon licenses and investigates complaints.

  • Practicing without a current license, or letting an unlicensed person perform services, is a prohibited act subject to penalty.

  • A salon must hold a salon license and designate a salon manager who is responsible for compliance and sanitation in the facility.

  • The license and current statutes and rules must be available in the salon for inspection by the board or its authorized agents.

  • A nail technician performs only services within the nail technician scope; anything outside that scope requires the matching license.

  • Board sanitation standards require cleaning and disinfecting implements after each client and discarding single-use items after one use.
