14.1 Nail Consultation, Analysis, Contraindications & Client Records
Key Takeaways
- A nail consultation evaluates the condition of the nail plate, bed, folds and surrounding skin on both hands or feet before any implement is picked up, because the decision to service is made in that inspection.
- Any sign of active infection — redness, swelling, warmth, pus, green or black discolouration, or broken skin — is an absolute contraindication requiring refusal of service and referral, and naming the condition would breach Wis. Admin. Code Cos 2.02.
- Clients with diabetes mellitus or peripheral circulatory disorders have reduced sensation and impaired healing, so pedicure services require gentle technique, no cutting of living tissue, cooler water, and physician clearance where the client's condition is unstable.
- Wis. Admin. Code Cos 1.01(3r) limits 'cutting' in the manicuring definition to the cutting of human nails, cuticles and calluses, so no licensee may cut living skin such as the eponychium.
- A nail service record documents the analysis, products and enhancement system used, maintenance interval, any lifting or reaction observed, and the home care advised.
14.1 Nail Consultation, Analysis, Contraindications & Client Records
Quick Answer: Look before you touch. Inspect every nail on both hands or both feet, plus the surrounding skin, under good light. Anything that is red, swollen, warm, weeping, green, black or broken stops the service. Decline privately, refer to a physician, and do not name the condition — Wis. Admin. Code Cos 2.02 prohibits a licensee from diagnosing any disease of the skin.
1. The Analysis Sequence
- Health and history intake. Diabetes, circulatory disorders, pregnancy, chemotherapy, allergies, current medications, previous reactions to enhancement products or adhesives.
- Service history. What system is currently on the nails — acrylic, hard gel, soak-off gel, wraps, polish — and how long since the last fill? Removing an unknown product with the wrong solvent damages the plate.
- Inspect the plate. Surface texture, ridges, splitting, discolouration, thickness, separation from the bed.
- Inspect the bed through the plate. Colour tells you about circulation and about what may be growing underneath.
- Inspect the folds and surrounding skin. Redness, swelling, warmth, tenderness, hangnails, breaks in the skin.
- Check both hands or both feet. A single affected digit is easy to miss when nine look fine — and one contraindicated nail contraindicates the service.
- Ask about sensation, particularly for pedicures on clients with diabetes or circulatory disease.
- Decide, then document. Proceed, modify, or decline and refer.
2. What You Are Sorting For
Every finding lands in one of three buckets. Learning the buckets, rather than memorising an endless list of names, is what the examination rewards.
| Bucket | Meaning | Examples |
|---|---|---|
| Serviceable disorder | Non-infectious, cosmetically manageable, often with technique modification | Ridges, leukonychia (white spots), Beau's lines, bruised nail, hangnail, onychorrhexis (split, brittle nails), onychophagy (bitten nails), discoloured nails |
| Modify or proceed with care | Not infectious, but the tissue is compromised | Very thin plates, severe brittleness, healed but fragile skin, mild callus, a client on blood thinners |
| Absolute contraindication | Active infection or broken skin — refuse and refer | Paronychia, onychomycosis and other fungal infection, pseudomonal green or black discolouration, tinea pedis, warts, open lesions, pus, unexplained swelling |
The visual triggers to memorise: redness + swelling + warmth + pus around a nail fold is an infection pattern. Green to black under a lifted enhancement is bacterial, most commonly Pseudomonas aeruginosa. Thickened, crumbling, yellow-brown, foul-smelling plate separation suggests a fungal infection. Any of these ends the service.
Exam Trap: refusing without diagnosing. "You have a fungal infection" is a diagnosis and is prohibited. "I'm not able to work over this — it needs a physician to look at it, and I'd be glad to book you once you're cleared" is compliant, professional and complete.
Never file, buff, cover or polish over a suspicious area. Concealing a green stain under polish traps moisture and feeds the bacteria; filing a fungal plate aerosolises spores across the workstation.
3. The Living-Tissue Boundary
Cos 1.01(3r) defines "cutting," as used in the manicuring definition at s. 454.01(13), as meaning exclusively the cutting of human nails, cuticles and calluses. Nothing in that list is living tissue.
The distinction that follows is one of the most heavily tested facts in nail care:
- The cuticle is dead, colourless keratinised tissue shed from the underside of the eponychium onto the nail plate. It may be softened and gently removed.
- The eponychium is living skin at the base of the plate, covering the matrix. It must never be cut, trimmed or nipped. Breaching it destroys the seal that protects the matrix and opens a direct route to paronychia.
And Wisconsin removes two callus tools from the table entirely: Cos 4.045 prohibits pumice stones and credo razors. Calluses are smoothed with a sanitised foot file carrying a single-use abrasive, never shaved.
4. Diabetes and Circulatory Compromise
This is the highest-consequence consultation issue in pedicure work. Clients with diabetes mellitus may have peripheral neuropathy (reduced or absent sensation, so they cannot feel a cut, a blister or water that is too hot) combined with peripheral vascular disease (reduced blood supply, so a small wound heals slowly or not at all). A minor nick that would be trivial on another client can become a serious ulcer.
| Modification | Reason |
|---|---|
| Cooler water and test it yourself | The client may not feel scalding water |
| No cutting of living tissue whatsoever | Any break in the skin risks a non-healing wound |
| Gentle filing, no aggressive callus reduction | Removing protective callus exposes fragile skin |
| Trim nails straight across, no deep sidewall work | Prevents ingrown nails and sidewall injury |
| Light massage; avoid vigorous work on the lower leg | Circulatory conditions such as varicose veins and any history of deep vein thrombosis contraindicate deep leg massage |
| Inspect thoroughly and report findings to the client | You may be the first person to see a developing problem on the sole |
| Physician clearance where the condition is unstable | Documented in the record |
The same caution applies to clients with varicose veins, a history of deep vein thrombosis, or any peripheral circulatory disorder.
5. Recommending Services and Products
Recommendation is part of the blueprint, and it follows directly from the analysis:
- Brittle, splitting plates (onychorrhexis) → cut back on solvent exposure, recommend a nail oil applied to the eponychium daily, and consider a strengthening system rather than a heavy enhancement.
- Bitten nails (onychophagy) → tips or wraps can protect the plate while it grows, provided the surrounding skin is intact.
- Repeated lifting at the sidewalls → almost always a preparation or product-ratio issue, not a client-behaviour issue.
- Dry, ragged eponychium → oil and gentle exfoliation, never nipping.
And the maintenance interval is a recommendation too: enhancements are filled at roughly 2 to 3 weeks, and fabric wraps take a stress strip across the apex at about 4 weeks once new growth has moved the stress point forward.
6. The Nail Service Record
| Field | Why |
|---|---|
| Health history, updated each visit | Diabetes and medication status change between appointments |
| Analysis findings for each hand or foot | Establishes the baseline and shows what was inspected |
| Enhancement system and brand used | Prevents an incompatible removal or overlay next visit |
| Products, primers and adhesives used | Lets any allergic reaction be traced to an agent |
| Maintenance interval and date of next service | Supports the fill schedule |
| Any lifting, discolouration or reaction observed | Documents the progression and the advice given |
| Home care recommended | Oil use, glove wearing, solvent avoidance |
| Any refusal of service and the referral given | The record that protects you if a client later complains |
Scenario. A regular client arrives for a fill. Nine nails are sound; the ring finger shows a dull green patch under a lifted corner. You remove nothing, cover nothing, and reapply nothing. You explain privately that you cannot work over that area and that a physician should look at it, note the finding and the referral in the record, service nothing on that nail, and rebook once she is cleared.
