NM Nail Technician cheat sheet

New Mexico defines three levels: cleaning (soap/detergent and water to remove debris), disinfection (EPA-registered hospital-grade tuberculocidal product on nonporous implements and surfaces), and sterilization (autoclave or dry heat, kills spores).

Implements that contact blood or broken skin - nippers, cuticle pushers that draw blood, metal bits - must be cleaned, then sterilized; porous items (buffers, files, wooden sticks, orange sticks, pedicure slippers) cannot be disinfected and must be discarded after one client.

Disinfectant contact time is set by the manufacturer's label (commonly 10 minutes for hospital-grade tuberculocidal products); implements must be fully immersed, and the solution must be changed per label and whenever visibly contaminated.

Hand washing with soap and warm water for at least 20 seconds is required before and after each client; alcohol-based hand rub is not a substitute when hands are visibly soiled.

Single-use items: gloves, cotton, paper towels, toe separators, and nail polish applicator wands. Gloves are changed between clients and whenever torn or contaminated.

Blood spill protocol: wear gloves, stop service, clean the area with soap and water, apply an EPA-registered disinfectant with the label contact time, and dispose of contaminated materials in a sealed bag; exposure to broken skin requires washing with soap and water and reporting to a physician.

Material Safety Data Sheet (SDS) must be on file for every chemical product in the salon; containers must be labeled, and products stored away from heat, flame, and food.

Electrical safety: no cords across walkways, no appliances near water, GFCI outlets required near sinks, and damaged cords removed from service.

A salon must have a hand-washing sink with hot and cold running water, soap, and single-use towels accessible to the work area; restrooms cannot substitute for the work-area sink.

Nail plate rests on the nail bed; the bed's dermis has longitudinal grooves (bed ridges) that create the plate's lengthwise ridges. The hyponychium is the seal under the free edge; the onychodermal band is the thickened area just behind it.

Matrix produces the nail plate; it is housed under the proximal nail fold and extends to the lunula. Damage to the matrix causes permanent deformity or grooves (Beau's lines from temporary interruption of growth).

Cuticle (eponychium) is the dead tissue adhering to the plate at the base; the cuticle and the proximal nail fold together form the seal that keeps bacteria out. The cuticle is never cut with nippers; only loose tissue is trimmed.

Nail growth: fingernails about 3 mm (roughly 1/8 inch) per month, toenails about 1 mm per month; complete replacement of a fingernail takes about 4–6 months, a toenail 9–12 months. Growth slows with age, cold, and poor circulation; it speeds up in summer and during pregnancy.

Layers of the nail plate: dorsal, intermediate, and ventral. The plate is mostly keratinized cells with low water content (roughly 15–18% in a healthy nail); flexibility increases with water content.

Skin layers: epidermis (outermost, keratinized, no blood vessels), dermis (nerves, glands, capillaries, collagen/elastin), and subcutaneous (fat, insulation). Nail matrix and bed sit on the dermis.

Free edge extends beyond the hyponychium; the sidewalls (lateral nail folds) and the nail grooves hold the plate in place. The lunula is the visible portion of the matrix, whitish because of the light-reflecting cells there.

Sebaceous glands are absent from the nail plate and nail folds; the nail plate itself has no glands and receives moisture only from the bed and surrounding skin.

Standard manicure sequence: sanitation of hands and station, client record and skin/nail assessment, removal of old product, shaping with a fine-grit file in one direction, soak, cuticle care (soften, push back with a rubber-tipped pusher, trim only loose tissue), massage, base coat, two color coats, top coat.

File in one direction from corner to center on natural nails with a 240-grit or finer file; sawing back and forth causes splitting and peeling. Shape determines wear: square, squoval, oval, round, and pointed.

Soaking softens the plate and cuticle; limit soak time and use warm, not hot, water. Dry the nail thoroughly before polish so product adheres.

Pedicure: use a separate, clearly labeled basin liner or disinfected basin; single-use liners are preferred. Reduce callus with a paddle or file only on the sole and heel, never on the nail or between toes, and never use a credo blade on clients with diabetes or circulatory problems.

Do not push back or trim cuticle on clients with diabetes, circulatory disease, or onycholysis; refer to a physician. Never use a metal pusher on a client with thin or damaged nails.

Massage strokes and pressure: effleurage (light, toward heart), petrissage (kneading), tapotement (tapping), friction (small circular). Avoid massage over inflamed, bruised, or broken skin and over varicose veins.

Nail polish removal: acetone for regular polish, non-acetone for acrylics/gels or dry nails; acetone dehydrates and is flammable. Soak cotton, wrap in foil, wait, and wipe from base to free edge.

Polish application: thin coats; base coat protects and improves adhesion, top coat seals and adds gloss. Cap the free edge on wrap-around wear. Store polish away from heat and light; thin only with polish thinner, never acetone.

Station setup: clean towel, covered or disinfected implements, single-use items, waste bag within reach, and a client record documenting services, products, and any observed conditions.

Nail tips: pre-shaped plastic extensions glued to the free edge. Match tip well/size to the natural nail's sidewalls; a tip that is too wide causes pressure and lifting. Blend the seam with a fine file or buffer so it disappears.

Tip sizing rule: choose the smallest tip that fully covers the free edge without overlapping sidewalls; file the well to fit rather than forcing a larger tip.

Silk and fiberglass wraps: repair and reinforce with a resin/cyanoacrylate adhesive over a mesh. Silk is softer and blends well for repairs; fiberglass is stronger and better for stress areas.

Wrap application: clean and dehydrate the plate, apply base resin, lay wrap, press out bubbles, apply two or three resin coats, then buff and seal. Bubbles trap moisture and cause lifting or infection.

Linen wraps are stronger than silk and less flexible; paper wraps are the weakest and are used for temporary repairs.

Nail wraps are not a substitute for treating a disease; if the nail shows discoloration, lifting with pain, or separation, stop and refer.

Removal of wraps: soak in wrap remover or acetone-free solvent per product instructions, then gently lift; never pry or force.

Tips and wraps must be applied to a clean, dry, oil-free nail; dehydrator and primer are used per manufacturer's instructions, and acid-based primers must not touch skin.

Overlay versus tip: an overlay adds strength to the natural nail without lengthening; a tip adds length. Document which was used and the product batch.

Acrylic (liquid and powder) chemistry: monomer (liquid EMA or MMA) plus polymer powder (PMMA) cured by polymerization, not by evaporation. MMA is banned in many states for nail use because of severe allergic reactions and damage; EMA is the standard.

Mix ratio: medium-dry bead; too wet causes shrinkage, lifting, and bubbles; too dry causes brittle, cloudy product. Ratio affects strength, cure, and adhesion.

Application zones: apply to the stress area and blend the product thin at the cuticle and sidewalls; product that touches the skin lifts and can cause allergic contact dermatitis.

Gel: oligomers cured by UV/LED light. Match lamp wavelength and cure time to the product; undercured gel causes service breakdown and allergic reactions. Keep gel off skin and cure fully.

Gel polish: base, color, top; bonder or primer only as directed. Removal requires soaking in acetone or filing; never peel cured gel - peeling removes plate layers.

Acrylic filing: use a medium-grit bit or file for shaping, fine for finishing; keep the bit moving, use light pressure, and avoid the eponychium and sidewalls.

Dehydration and primer: dehydrate the natural plate, then apply primer per manufacturer; acid primers etch and must not contact skin or eyes.

Lifting causes: moisture on the plate, oil, product touching skin, wrong mix ratio, insufficient filing of the natural nail, and trauma. Fix by proper prep, not by more product.

Safety: work in a ventilated area, keep monomer and powder containers closed, wear gloves and a dust mask when filing, and never mix brands of liquid and powder.

Nail technicians may not diagnose or treat disease. Identify and refer: any condition with pain, swelling, pus, red streaks, fever, or a dark streak under the nail requires medical evaluation.

Fungal infection (onychomycosis): yellow-brown, thickened, crumbly, lifting plate, often on toenails; highly contagious. Do not service; refer. Do not share files or implements.

Paronychia: red, swollen, painful nail fold, often with pus; bacterial or fungal. Do not massage or push back; refer.

Onycholysis: separation of the plate from the bed, usually white and painless, caused by trauma, aggressive cleaning, or psoriasis. Do not push product under the free edge; refer if painful.

Beau's lines: horizontal depressions from interrupted matrix growth due to illness, injury, or severe stress; they grow out. Pitting (small dents) is associated with psoriasis.

Koilonychia (spoon nails) is associated with iron deficiency; clubbing with pulmonary or cardiac disease; both require referral, not cosmetic masking.

Melanonychia: dark longitudinal band, especially on one nail, needs medical evaluation to rule out melanoma. Subungual hematoma from trauma is usually dark and grows out.

Brittle nails and leukonychia (white spots) are common and usually cosmetic; white spots often follow minor trauma to the matrix, not calcium deficiency.

Hangnail (agnail) is torn cuticle/skin; trim only the loose tag with sterile nippers and refer if infected. Do not pull.

Consultation sequence: greeting and intake form (allergies, medications, health conditions, pregnancy, diabetes), visual assessment, discussion of goals, service plan, consent, then service.

Contraindications to ask about: diabetes, circulatory problems, blood thinners, skin conditions, nail infections, recent surgery, allergies to acrylics, nickel, or latex.

Patch test for new products on clients with known sensitivities; record the product, date, and result.

Informed consent: explain the process, risks (lifting, allergic reaction, filing damage), aftercare, and cost before starting; document the client's approval.

Confidentiality: client records and health information are private; discuss services only with the client and authorized staff, and store records securely.

Scope of practice: the technician does not diagnose, prescribe, or treat; when a condition is outside scope, refer to a physician or dermatologist and document the referral.

Communication: use plain language, avoid jargon, ask open-ended questions, confirm understanding, and never make claims of curing or healing.

Conflict and complaints: listen, acknowledge, offer a remedy within policy, document the incident, and follow up. Do not argue in front of other clients.

Aftercare instructions: keep nails dry for the first hours, use cuticle oil, avoid using nails as tools, return for maintenance, and report pain, redness, or lifting.

Nail technician licensure in New Mexico is administered by the Board of Barbering and Cosmetology within the Regulation and Licensing Department; a license is required to perform services for compensation.

Licensure requires completion of an approved nail technology program (hours set by Board rule) and passing the Board-approved written and practical examinations; verify current hour requirements directly with the Board because rules change.

License renewal and continuing education requirements are set by Board rule; licenses must be posted or available at the work location, and a licensee must carry identification.

Salon licensure: the establishment must hold a current license, display it, and pass inspection. A licensed technician may not work in an unlicensed establishment.

Sanitation rules mirror the Board's standards: hospital-grade disinfectants, sterilization of blood-contact implements, single-use porous items, and a work-area hand sink with soap and single-use towels.

Scope and delegation: only licensed persons may perform nail services; apprentices and students work under supervision per Board rule and may not take compensation independently.

Advertising may not be false or misleading and may not claim to treat or cure disease; use the licensed title accurately.

Discipline: the Board may suspend, revoke, or fine for unsanitary practice, unlicensed practice, or fraud. Clients may file complaints with the Board.

Always verify current statutes (NMSA Chapter 61) and Board rules on the RLD website; hour, fee, and CE figures change and must be confirmed before relying on them.
