Tips, Wraps, and Enhancements: Application, Structure, and Removal
The three families
Tips and forms are structure builders, not a product category. A tip is a pre-shaped extension glued to the free edge and blended at the seam; a form is a reusable or disposable mold placed under the free edge so product can be sculpted. Wraps (silk, linen, fiberglass, paper) are applied over the natural nail or a tip and saturated with resin and activator; they add strength with minimal bulk. Liquid-and-powder (acrylic) systems combine monomer liquid with polymer powder; light-cured gels and dip systems are the other common enhancement types. Know which needs a primer, which needs a lamp, and which is removed with acetone versus a file.
Correct structure and ratio
An enhancement should be thin at the cuticle, build to an apex at the stress zone (the area over the free edge where the nail flexes), and thin out at the tip. Too thick and it lifts; too thin and it cracks. In acrylic, the liquid-to-powder ratio controls curing: a wet, runny bead shrinks, lifts, and yellows, while a dry bead crumbles and leaves air pockets. The bead should look like a saturated snowball that holds its shape and stops being tacky as it sets.
Prep and aftercare
Prep is the whole game: sanitize, inspect, push cuticle, remove shine from the nail plate with a fine-grit file without thinning it, dehydrate, and apply primer only as the label directs. Do not touch the skin with primer or monomer. Fills are typically scheduled every two to three weeks; the service includes reducing the product, rebalancing the apex, and blending the new product into the old. Removal must never involve ripping, biting, or prying - this tears nail plate layers and leaves white spots.
Rule of thumb: product on skin causes lifting, so the answer to "why did the enhancement lift?" is almost always product touching cuticle or sidewall, moisture, or skipped prep - not the brand.
Contraindications
Broken skin, active infection, severely damaged plates, and known allergy to monomer or resin mean no enhancement service.
Anatomy, Physiology, and Nail Structure: The Nail Unit and What It Signals
The nail unit
Nail plate - the visible, hard keratin structure with no nerves or blood vessels of its own. Nail bed - the pink tissue the plate sits on, laced with capillaries. Matrix - the living tissue under the proximal nail fold that produces the plate; it determines thickness, shape, and growth rate, and injury here causes permanent distortion. Lunula - the visible, whitish part of the matrix at the base. Cuticle - dead tissue sealing the plate at the base; eponychium - the living proximal fold; hyponychium - the seal under the free edge; lateral folds - sidewalls; free edge - the portion extending past the fingertip.
Growth and physiology
Fingernails grow roughly 3 mm (about 1/8 inch) per month; toenails grow more slowly, roughly 1.5 mm per month. Growth is faster in summer, in youth, and on the dominant hand, and slows with age and poor circulation. Nails are composed mainly of keratin; the plate's condition reflects nutrition, hydration, and health. The surrounding skin has epidermis and dermis with blood vessels, nerves, glands, and hair follicles; the hands and feet are richly innervated, which is why trauma is painful and why a technician's incautious tool use matters.
Conditions you must recognize and not treat
- Onychomycosis - fungal infection; thick, yellow-brown, crumbly plate; refer.
- Paronychia - red, swollen, painful nail fold; bacterial; refer.
- Onycholysis - plate separating from the bed.
- Beau's lines - horizontal depressions from illness or trauma to the matrix.
- Koilonychia - spoon-shaped nails.
- Leukonychia - white spots, usually minor trauma.
- Melanonychia - dark longitudinal band; needs medical evaluation.
- Agnail (hangnail) - a small tear in dead tissue; may be clipped with clean nippers.
Rule of thumb: pain, pus, odor, dark streaks, sudden thickening, separation, or a new lesion equals stop and refer. You beautify the plate; you never diagnose or treat.
Practical application
Because the matrix creates shape, shaping the free edge cannot change the nail's natural form, and aggressive cuticle work at the proximal fold risks permanent damage to the source of growth.
Business Practices, Ethics, and New York State Law
Who regulates what in New York
New York licenses nail specialty as an appearance enhancement specialty through the Department of State, Division of Licensing Services. There are three layers to keep straight, and exam questions frequently swap them: the individual practitioner license (requires completion of an approved program - 250 hours for nail specialty - plus the written and practical examinations), the appearance enhancement business license held by the shop itself, and the sanitation standards enforced on the premises and on each service. A practitioner may not work in an unlicensed shop, and a shop may not employ an unlicensed practitioner. Both licenses must be available for inspection, and only services within your licensed scope may be performed or advertised. Renewal and continuing-education obligations follow the Department's current schedule - verify rather than guess.
Scope of practice
Nail specialty covers cutting, trimming, filing, shaping, cleansing, polishing, coloring, tinting, manicuring, pedicuring, applying artificial nails and tips, and massaging the hands, arms, and feet. It does not include diagnosing or treating disease, cutting living tissue, removing corns or plantar lesions with a blade, or injecting anything. Redness, pus, dark streaks, and ingrown nails are referrals, not challenges.
Ethics in practice
Informed consent before service, honest pricing and no bait-and-switch, confidentiality of client health information, refusal to serve a contraindicated client, full disclosure of product risks, no working with an active infection or open lesion, and no misrepresentation of credentials. Ethical behavior also means not diagnosing, not selling a "cure" for a fungal nail, and not photographing clients without permission.
Business basics
Know the difference between commission employment (the shop withholds taxes and supplies the location) and booth rental (you are self-employed, responsible for your own taxes, insurance, and supplies). Carry liability insurance, keep client records, price services to cover product, time, and overhead, and remember retail product sales generally carry sales tax while services are treated separately under state rules.
Rule of thumb: if a task could injure, diagnose, or treat, it is not yours to bill for - refer.
