Green Nail and a Dark Band
A new client, 43, books a fill on a four-week-old acrylic set applied at another salon. On the right index finger the product has lifted along the sidewall and free edge; beneath it, the nail plate is stained green-black over roughly half the nail bed. There is no pus, no swelling, and she reports no pain, but the area has a faint musty smell. On the left thumb a single 2 mm brown band runs from cuticle to free edge; she says it has "always been there," but adds that it looks darker than last year. She wants both nails covered before a wedding in three hours and says, "Just wipe the green one with alcohol and build over it - I don't have time for a doctor."
1. What do you do with the right index finger today, and what determines whether product can go back on it?

Assessment: green-black discoloration confined to a pocket under lifted product is most consistent with Pseudomonas colonization of the space between the enhancement and the plate - the classic "greenie." The color is in the keratin, so wiping will not remove it.
What a nail technician may do:
- Remove the enhancement (soak off or file down carefully) so the plate can dry and be observed.
- Do not abrade the plate further, do not puncture, scrape, or drain anything, and do not apply medication.
- Cleanse gently, dry, and leave the nail bare.
What governs reapplication: the plate must be intact, dry, and free of separation, discoloration, and any sign of infection. Product must not go back on while discoloration persists - sealing it recreates the warm, dark, moist pocket that let the organism grow.
Referral triggers: pain, swelling, warmth, pus, spreading redness, fever, or the nail lifting from the bed. Alcohol wiping does not sterilize and does not make a contaminated pocket safe to cover; it is disinfection theater, not a control measure.
2. How do you handle the left thumbnail - what do you say, what do you write, and why is covering it a bad idea?

The reasoning: a single-digit longitudinal brown band can be benign (trauma, melanonychia, a nevus) or can be subungual melanoma. Findings that raise concern include a single digit, a band that widens or darkens, blurred edges, pigment spreading onto the cuticle or adjacent skin (Hutchinson sign), nail splitting, and older age. She reports it looks darker - that is a change, and change is the finding that matters.
What you say: "There's a brown band on this nail, and you mentioned it looks darker than before. I'm not qualified to diagnose nails - but a change like that in one nail is something a dermatologist should look at. I'd rather you get it checked than have me cover it."
What you write down: date; exact description (width, location, color, whether pigment touches the cuticle); the words "advised dermatology evaluation"; her response; and her signature. Descriptive language only - never a diagnosis.
Why covering it is a bad idea: opaque product hides progression and delays diagnosis, and it prevents you from monitoring the nail at each visit. When a nail is under investigation, leave it bare or use clear polish only, and say why.
3. She pushes back on the three-hour deadline. Give the reasoning behind your refusal and the option you can offer.

Refusal reasoning (state it plainly, without lecturing):
- "I can't build over a nail that's separating and discolored. That's how it gets worse, and treating it isn't something I'm licensed to do."
- "The color is in the nail, not on it - alcohol won't remove it, so building over it just hides a problem."
- The schedule does not change the clinical picture. One bad outcome - spreading infection, permanent plate damage, a complaint - costs more than one appointment.
Options you can offer:
- Manicure on the other nine nails, natural finish on the affected nails, so she still leaves polished and presentable.
- If a doctor clears the index finger later, book a rebuild then.
- Clear polish on the thumbnail only if she understands the monitoring caveat, or leave it bare.
If she insists on the full set, you may decline the service entirely. Decline politely, offer the alternative, and document both the advice and her decision.
