IL Nail Technician cheat sheet

The Illinois Department of Financial and Professional Regulation (IDFPR) issues and renews both the individual nail technology license and the salon establishment license.

Illinois requires 350 clock hours of approved nail technology training at a licensed school before a candidate may sit for the licensure exam.

Nail technology licenses renew on a two-year cycle and require continuing education for renewal; both the individual and the establishment license must be current and posted.

Methyl methacrylate (MMA) liquid monomer is prohibited in Illinois; only approved monomers such as ethyl methacrylate (EMA) may be used.

Performing manicures, pedicures, or nail enhancements for compensation without a valid license is unlawful and subject to disciplinary and civil penalties.

Every implement must be cleaned and disinfected before reuse on another client; single-use porous items must be discarded after one client.

A licensee may not perform services on skin that is broken, inflamed, or infected, and must refer the client to a physician instead.

Establishments are subject to state inspection, and sanitation records, product labels, and licenses must be available for review on request.

Required sequence for reusable implements: scrub with soap and water to remove all debris, rinse, dry completely, then immerse in an EPA-registered hospital-grade tuberculocidal disinfectant.

Disinfection is only effective when the implement stays fully submerged for the entire label contact time (commonly 10 minutes) at the label dilution.

Porous items - files, buffing blocks, foam separators, wood sticks, cotton - absorb liquids, cannot be disinfected, and must be single-use.

Quaternary ammonium disinfectants should be checked with test strips and replaced per manufacturer instructions or when the solution becomes cloudy or contaminated with debris.

UV light cabinets and alcohol dips are not substitutes for hospital-grade disinfection; alcohol is a low-level disinfectant only.

Hand hygiene: wash with soap and running water for at least 20 seconds; hand sanitizer is not a substitute when hands are visibly soiled.

Blood or body fluid exposure: stop the service, keep gloves on, cleanse the area with an antiseptic, bandage, and disinfect all contaminated surfaces and implements.

Sterilization by autoclave is a higher level of control than disinfection and is required for implements that pierce skin or contact blood.

Decision rule: if an item cannot be fully immersed and soaked, treat it as single-use.

The nail plate is composed of keratinized cells produced by the matrix; matrix damage produces ridges, thickening, or permanent distortion.

Fingernails grow about 0.1 mm per day (roughly 3 mm or 1/8 inch per month); toenails grow about 1 mm per month.

The lunula is the visible portion of the matrix at the base of the nail; the eponychium (cuticle) is living tissue that seals the matrix.

The hyponychium seals the area under the free edge; the lateral nail folds and nail sulcus border the sides of the nail plate.

The nail plate itself has no nerve endings, but the nail bed and surrounding folds are richly supplied with nerves and blood vessels.

Each hand has 27 bones: 8 carpals, 5 metacarpals, and 14 phalanges.

Skin has three layers: epidermis (no blood vessels), dermis (nerves, glands, vessels), and subcutaneous tissue.

Nail growth and appearance are affected by age, general health, nutrition, seasonal change, trauma, and medication.

Over-filing thins the nail plate and reduces its ability to protect the nail bed; the natural plate should remain intact.

Standard manicure sequence: consultation, hand washing, shaping and filing, cuticle care, massage, base coat, two color coats, top coat.

File natural nails in one direction from side to center with a fine-grit file; back-and-forth sawing causes splitting and peeling.

Trim toenails straight across and gently round the corners with a file to reduce the risk of ingrown nails.

Limit foot soaking to about 5-10 minutes; prolonged soaking macerates skin and softens the nail plate.

Contraindications for service: paronychia, onychomycosis, bacterial infection, open wounds, severe inflammation - decline and refer.

Diabetic clients: use lukewarm water, avoid sharp implements and aggressive callus reduction, and do not service broken skin.

Massage strokes: effleurage (light gliding, toward the heart) to open and close, petrissage (kneading) for deeper work; avoid varicose veins and inflamed areas.

Apply polish in thin coats; a base coat prevents staining of the nail plate and a top coat seals and adds gloss.

All implements are per-client; table surfaces are disinfected and linens are single-use or freshly laundered between clients.

Acrylic systems combine a liquid monomer with a powder polymer; the bead must be smooth and hold its shape - too wet causes shrinkage, lifting, and skin overexposure, too dry causes brittleness.

Acid-based primers (methacrylic acid) are applied to the nail plate only, never to skin or surrounding tissue.

The natural nail plate must be dehydrated and lightly buffed but never over-filed; thinning causes sensitivity and lifting.

Gel products cure only under the correct UV/LED wavelength; uncured product left on skin or cuticle is a common cause of allergic reaction.

Removal: file down the bulk, saturate with acetone or the manufacturer's remover, wrap, allow time, then gently lift; never pry, force, or nip product off.

Signs of allergic contact dermatitis (itching, redness, swelling, lifting) require removal of the product and referral to a physician.

Monomer must be stored in a closed container and dispensed with a pump or dropper; open dishes increase evaporation and inhalation exposure.

MMA monomer is prohibited in Illinois; only EMA-based or otherwise approved monomers are permitted.

Safety Data Sheets contain 16 sections covering identification, hazards, composition, first aid, firefighting, handling, and disposal; they must be accessible in the salon.

GHS label elements include product identifier, signal word (Danger = more severe, Warning = less severe), hazard statements, and precautionary statements.

GHS pictograms relevant to nail products include flame, exclamation mark, health hazard, and skull and crossbones.

Acetone is highly flammable; keep it away from open flame, sparks, and heat and store it in the original closed container.

Nitrile gloves resist methacrylate monomers; latex gloves degrade and do not protect the technician.

Use local exhaust ventilation and keep containers closed when not in use to keep vapor exposure below occupational limits.

Never mix products from different brands or substitute household chemicals; reactions and contamination are unpredictable.

Skin pH is about 4.5-5.5; strongly alkaline or acidic products disrupt the barrier and lead to contact dermatitis.

Overexposure warning signs include headache, dizziness, nausea, and skin or respiratory irritation.

Consultation covers medical history, medications (especially anticoagulants), allergies, occupation, lifestyle, and expected outcome.

Patch test adhesive or enhancement products 24-48 hours before the first service for clients with a history of sensitivity.

Scope of practice: the technician may recognize signs of disease and refer, but may not diagnose or treat any condition.

Decision rule: broken skin, visible infection, or unexplained discoloration means no service and a referral.

Confirm informed consent - service steps, products, risks, and price - before beginning work.

Record each service: date, products and lot numbers, observations, and any reaction; records are confidential and support traceability.

Active listening and non-judgmental language build trust; avoid promising medical outcomes or making diagnoses.

Professional boundaries: do not discuss other clients, do not gossip, and do not disclose client information without consent.

Price floor: service price must cover product cost, labor, allocated overhead, and target profit, or the service loses money.

Gross margin = (price − product cost) ÷ price, expressed as a percentage; use it to compare service profitability.

Cost per service = total container cost ÷ number of services obtained from that container; recalculate when product sizes or prices change.

Inventory control uses FIFO (first in, first out) and tracks expiration dates so liquids do not separate or expire on the shelf.

Booth rent: the renter pays a fixed fee for space, sets their own hours and prices, and is generally treated as an independent contractor.

Employee status differs from booth rent in that the salon controls schedule, pricing, and training, and handles payroll taxes.

Professional liability insurance protects the technician against claims arising from services performed.

Retail sales of products are generally subject to state sales tax, while personal services are treated differently; confirm current Illinois rules.

Ethics: do not solicit another salon's clients while employed there, do not disparage competitors, and honor posted prices and policies.
