Nail Art, Polish, and Finishing Techniques
Nail art questions are about design judgment and cross-contamination, not just creativity.
Design principles
Balance, proportion, and symmetry. The design should follow the nail shape: a long oval can carry a vertical line, while a short square reads better with a small accent or French tip. Place the focal point where the eye lands - near the tip or the base - not dead center on a short nail.
Products
Lacquer, gel polish, acrylic paint, stamping polish, foil, glitter, rhinestones, decals, and encapsulation. Use thin coats; thick polish pools, wrinkles, and never dries through. A matte top coat changes the finish without changing durability.
Techniques
Hand painting, stamping, foiling, marbling, ombré, French, and encapsulation. Dry or cure each layer before adding the next.
Cross-contamination
Never double-dip a brush into a shared bottle after touching a client. Pour polish into a disposable cup, use disposable applicators, and discard. Clients with a suspected infection get no shared product at all.
Finishing
Cuticle oil, hand massage, and a final inspection. Photograph only with the client's permission and never post identifying images without consent.
Worked example
A client wants rhinestones on a short, active-lifestyle nail. Correct reasoning: use small stones, set them in gel top coat away from the free edge, and cap them so they do not catch. Oversized stones on a short nail lift within days.
Traps
Flooding the cuticle with polish; double-dipping; using craft glitter not rated for nails; overbuilding a design so it snags; ignoring the client's requested shape.
