The Green Thumb Before the Wedding
Three and a half weeks after a full set applied at another salon, a client books a fill. Both thumb sidewalls have lifted, and under the right thumb's lifted edge is a dark green-black patch on the natural nail plate that does not wipe away and has a faint smell. She is a bridesmaid in three days, has $35 with her, and asks you to "file it flat and cover it with the opaque pink so nobody sees it." She also asks whether you use MMA liquid, because a shop across town charges $25 and "those nails never lift." Your fill is $50 and you use EMA monomer.
1. Identify the green-black patch, explain why covering it is the wrong move, and lay out the correct procedure.

What it is. A green-black stain under a lifted enhancement, with a smell and trapped moisture, is the classic presentation of Pseudomonas aeruginosa colonization - what the industry calls "greenies." It is bacterial, not fungal, and it lives in the gap where water gets under lifting product and cannot evaporate. The stain itself is pigment in the nail plate and can persist for months as the nail grows out.
Why covering it fails. Opaque pink does not treat anything; it removes light and air from an active bacterial environment and hides a problem that may worsen. You would be sealing in the very conditions that caused it, and you would be the last person who saw it before it spread.
Correct procedure:
- Tell the client what you see, in plain terms, before you touch anything.
- Remove all product over the affected area - do not file down to it and do not drill into a lifted zone where debris can be driven deeper.
- Clean gently with a soft brush and soap; do not dig or scrape the plate.
- Let it dry, keep the nail bare, and disinfect every implement that touched it.
- Refer if there is pain, redness, swelling, pus, or the discoloration extends onto the nail fold - those are signs of infection that need a physician.
She may be unhappy. That is a conversation about the wedding, not a reason to skip step 2.
2. How do you handle the MMA question and the $25 comparison, both technically and professionally?

Technically: MMA (methyl methacrylate) monomer has not been cleared by the FDA for cosmetic nail use, and many states restrict or prohibit it; check the current text of WAC 308-20 and your salon's written policy before you quote a rule to a client. What you can say with certainty is what it does: it is a harsh solvent, it cures hard and brittle with poor adhesion to the natural nail, and it is typically removed by soaking or prying, which takes plate with it. "Those nails never lift" is often "those nails cannot be safely removed."
The price conversation: do not match $25 by deleting steps. Your price includes a clean, disinfected station, an EMA monomer, a proper removal protocol, and the time to look at what she has on her nails today. Say that out loud: "I use a different product and I spend more time on prep and sanitation. I can't do this safely for $25, and I won't pretend I can."
Do not criticize the other shop by name or imply the client was harmed - you have not seen their work beyond this one thumb, and disparaging another business is unprofessional and, in a small market, remembered.
Do give her a real choice: a full fill today at your price, a removal and natural-nail service she can afford today, or a rebook. Never let a budget gap push you into using a product your judgment rejects. The client's $35 does not create an exception to your standard.
3. Build a service plan that gets her to the wedding safely.

Constraint stack: three days, $35 cash, one obviously affected thumb, and a client whose emotional stakes are high.
Plan:
- Right thumb: remove product over the discoloration, clean, leave bare. No polish. Explain that the stain will grow out and that a bare nail photographed at a distance is invisible compared to an infection she will be dealing with for months.
- Other nine nails: assess each - if the rest is sound, do a proper fill or rebalance on those and finish them in the wedding color. Matching the thumbs can be done with a natural, unpolished look on the affected one, or with a small, honest explanation if anyone asks.
- If the green area is small, dry, and clearly improving and she still wants coverage, that is still a conversation, not an automatic yes - and if coverage is done at all, it should be after a drying period and with her written acknowledgment, not on the same day she walked in with a smell.
- Cost: prioritize. If $35 buys a rebalance on nine nails, do that and leave the thumb. Under-promise on scope, not on safety.
- Disinfection: every file, bit and brush that contacted the affected nail is cleaned and disinfected on a timed batch before it touches anything else; porous items are discarded.
Close the loop: book a two-week check on the thumb, document what you saw and what you declined to do, and note that she asked for it to be covered. That note is your protection if she later says you hid a problem.
