Green-Black Discoloration Under a Lifted Acrylic
Thursday, 3:15 p.m. A regular client, 41, arrives for a fill on a four-week-old acrylic set. On the right index finger the product has lifted about 4 mm along the sidewall, and the natural plate under the free edge shows a dark green-black patch roughly 6 mm across. The lateral fold is slightly swollen, and she says the finger has throbbed since Monday. There is no pus, no red streaking up the finger, and no fever. She has a wedding on Saturday and wants you to soak off the set, scrub the nail with alcohol, and put a fresh set on so nobody sees it. Your station is already set up for a fill, the salon is fully booked, and your next client is due in 45 minutes. The owner tells you to keep the schedule moving and just work around the spot.
1. Do you perform the service the client requested? Give the clinical and regulatory reasoning you would use, and what you say to her.

No - you do not apply product over that nail, and you do not scrub it with alcohol and cover it.
The picture matters: discoloration confined under a lifted enhancement, a swollen lateral fold, and throbbing. That cluster is not a cosmetic flaw, and a nail technician is licensed to cleanse, shape, and beautify nails - not to diagnose or treat a bacterial or fungal condition. Green-black under a lifted edge is commonly bacterial colonization (Pseudomonas is the classic), sometimes with fungal involvement; either way the decision belongs to a physician or nurse practitioner.
Sealing the plate under acrylic creates a warm, dark, damp chamber that favors growth, can convert a low-grade colonization into a painful paronychia, and hides the progression from whoever eventually treats it. Alcohol is a surface antiseptic - it does not sterilize the plate, does not reach organisms under a fold, and does not make the nail safe to cover.
Say it plainly: I can't diagnose this, but what you're describing needs a doctor before anyone puts product back on it. Offer the referral, put nothing on that finger, and do not let the owner's schedule argument change the answer. Declining a service you should not perform is not a customer-service failure.
2. What do you document, what do you say about rebooking, and who absorbs the cost of the lost slot?
Read the worked answer
Document contemporaneously, as you would for any service: date and time, client name, the specific finger, the size and location of the discoloration, the degree of lifting, the swelling, the client's reported symptoms in her words, her exact request, that the service was declined, and the referral you gave. Have her sign or initial the note and keep it with your service records. The note is your protection if she later says you injured her or if the salon disputes your decision.
Give the referral in writing - name of a clinic, dermatologist, or her primary care office - plus a simple instruction: ask them to confirm in writing when the nail is clear before a new set. That converts a vague promise into something you can actually schedule against.
Rebooking: offer a date after clearance, not a deposit-free hold for Saturday. Explain that you cannot promise a date because clearance depends on the provider. The lost slot is a business cost of the salon, not a fee to charge her. Do not charge for the declined fill, and do not soak off the whole set as a paid service on that hand if it means manipulating the affected nail.
3. Could you still service the other nine nails? Describe the precautions and the limits.
Read the worked answer
Usually yes, if she wants it and you separate the affected finger completely from the workflow.
Practical sequence: wash your hands, set up fresh implements, and work on the unaffected nails. Keep the affected finger out of any shared soak - use a disposable liner or a bowl reserved for her, and discard the liner. Do not double-dip any product, do not use the same pusher or nippers on that finger and then on the others, and do not file the discolored plate at all, because debris and dust carry organisms to your file, your towel, and your lap.
Gloves on for the whole service, changed if you touch the affected area. Anything porous that touches that finger - file, buffer, orange stick, wipe - goes into the trash or into a bag that leaves with her; it does not go back into the drawer. Metal implements used near it get washed, dried, and full-label-contact-time disinfected before reuse.
Limits to state out loud: you are not cleaning out the pocket, not trimming the swollen fold, not applying any product to that nail, and not giving her a home remedy that sounds like treatment. Refer, document, and let her decide about the rest.
