Study notes

Infection control

This is the largest block on the exam and the thing inspectors actually check. New Jersey updated its own language here — what older textbooks call sanitization and sterilization, the state now calls decontamination and infection control. Learn the state's wording.

Three levels, in order of strength

• Cleaning — soap, water, and a brush. Physically removes debris. It is not disinfection, but nothing can be disinfected until it is clean first.
• Disinfection — an EPA-registered, hospital-grade product that kills bacteria, viruses, and fungi. This is the required level for reusable metal implements between clients.
• Sterilization — kills everything including spores. Requires an autoclave. Not typically required for a manicuring service, but know what it means and why it is stronger.

Rules that come up constantly

• Single-use is single-use. Nail files, buffers, orangewood sticks, and toe separators that are porous get thrown away after one client. They cannot be disinfected.
• UV boxes are not disinfection. A light box is storage at best. It does not replace an EPA-registered disinfectant.
• Solution gets changed. Cloudy or debris-filled disinfectant is no longer working. Fresh solution, per label instructions.
• Hands first. Wash your own hands before every service, in front of the client.
• Double-dipping is contamination. Anything that touches a client does not go back into a shared container.

What New Jersey forbids

The prohibited-practices rule lives at N.J.A.C. 13:28-2.15. These come up as exam questions and as license discipline, so they are worth knowing by name.

• No credo blades, skin scrapers, or lancets. Any implement that cuts below the skin surface to remove callus is prohibited outright — not just discouraged, and it should not even be present in the shop.
• No services on infected or damaged nails. Polish or an overlay applied over an infection, injury, or trauma is a violation. The correct move is to decline and refer.
• No medical claims. A manicurist cannot offer to cure, remedy, or treat any disease or condition.
• No work below the stratum corneum. Anything that breaks living skin is outside the scope of the license.
• No medical devices beyond FDA Class One, no skin tag removal, no permanent cosmetics, no teeth whitening.

Nail anatomy

Written exams love these terms because the everyday salon words and the correct words are different. Learn the correct ones.

• MatrixThe living tissue under the skin at the base of the nail where the plate is actually made. Damage here means permanent deformity. Never file, drill, or press into it.
• Nail plateThe hard visible nail. Made of keratin. It is dead tissue, which is why filing does not hurt.
• Nail bedThe living skin the plate sits on and slides forward over as it grows.
• LunulaThe pale half-moon. It is the visible front edge of the matrix.
• EponychiumThe living skin at the base of the nail. Push it back gently. Never cut it.
• CuticleThe thin dead tissue that sticks to the plate itself. This is the part that is safely removed. Most people use "cuticle" for both — the exam does not.
• HyponychiumThe seal of skin under the free edge. Breaking this seal opens a route for infection.
• Free edgeThe part of the plate past the fingertip.
• Sidewalls and nail foldsThe skin along the sides. Filing into them causes ingrown nails.

Service it or refer it

A disorder is a condition you may usually work around. A disease means hands off and a referral to a physician. Getting this wrong is both an exam failure and a real liability.

Generally serviceable

• Ridges — vertical lines from age or trauma. Buff lightly, do not thin the plate.
• Leukonychia — white spots from minor trauma. Harmless, they grow out.
• Hangnail — split skin at the sidewall. Trim the loose skin only, condition the area.
• Bruised nail — dark spot from an impact. Do not apply an enhancement on top of it.
• Bitten nails — service as long as the skin is not broken.

Decline and refer

• Onychomycosis — fungal infection. Thick, crumbling, discolored, often lifting.
• Paronychia — infection of the tissue around the nail. Red, swollen, warm, sometimes pus.
• Pseudomonas — the green-black stain between plate and bed, usually under a lifted enhancement. Bacterial.
• Onycholysis — the plate separating from the bed. Refer and do not fill over it.
• Pterygium — living tissue growing abnormally onto the plate. Never cut or force it.
• A new dark streak in one nail — this can be serious. It is not a stain and not a bruise. Refer to a doctor, every time, without alarming the client.
• Any open, weeping, or inflamed skin.

Product chemistry

You do not need to be a chemist, but you do need to know why gel behaves the way it does. Understanding this fixes lifting problems faster than trying a new brand.

• Monomer, oligomer, polymer. A monomer is a single unit. Oligomers are short chains — that thick, gooey texture gel has in the bottle. Polymerization links them into the long chains that make a hard, finished nail.
• Gel does not dry. It cures. A photoinitiator in the product reacts to a specific wavelength of light and triggers polymerization. That is why a wrong or dying lamp gives soft, tacky, peeling sets even when the application was perfect.
• Lamp and product must match. UV and LED lamps emit different wavelengths. A product formulated for one may not fully cure under the other.
• The inhibition layer is the sticky film left after curing — uncured product at the surface where oxygen interfered. It is normal. Wipe it with cleanser, and understand that it is also what lets layers bond to each other.
• Adhesion is about the surface, not the product. Oil, moisture, and residual cuticle are the usual cause of lifting. Prep, dehydrate, and cap the free edge.
• Overexposure is real. Repeated skin contact with uncured product is how technicians and clients develop permanent allergies to gel. Keep product off the skin. That is a career-preserving habit, not a nicety.
• Ventilation and dust. Filing dust and vapors accumulate over a career. Local ventilation and a proper dust mask from day one.

The practical exam

The practical is timed, and examiners grade sanitation at least as hard as they grade the finish. A beautiful set with a sloppy setup fails. A plain, correct, clean manicure passes.

1. Set up the station. Clean surface, disinfected implements laid out, single-use items sealed until used, waste container ready.
2. Wash your hands where the examiner can see it.
3. Inspect the client's hands and state any condition you would decline. Examiners plant these.
4. Remove existing polish, working base to free edge.
5. Shape with the file, moving in one direction, no sawing into the sidewalls.
6. Soften and gently push back the eponychium. Remove cuticle from the plate only. Nothing gets cut.
7. Cleanse, rinse, and dry thoroughly.
8. Massage, then remove all oil from the plate before polish.
9. Base coat, color, top coat — thin, even, capped.
10. Break down the station and start the disinfection process on used implements while the examiner is still watching.

Practicing this exact sequence at home now, on a timer, is the single highest-value thing to do before the course starts.

A study rhythm that works

Ten months is a long runway and the temptation is to do nothing until August. A light, regular pattern beats cramming, and it costs almost no time.

• One chapter a week from Milady Standard Nail Technology. That alone finishes the book before the program starts.
• Write your own flashcards for terms, rather than downloading someone else's. Making them is most of the learning.
• Narrate your practice sets out loud as if an examiner were watching. Naming the step is how it becomes automatic under pressure.
• Time one full manicure a month and note where the minutes go.
• Keep a lifting log. Date, product, prep method, and how long the set lasted. After twenty entries the pattern is obvious.
