Green Nail Plate After Home Acrylic Removal
Marisol, a 29-year-old client, arrives with a green-black discoloration on the nail plate of her right index finger. She removed acrylics at home three days ago and wants a new full set today. She says the nail 'looks gross' but does not hurt. On inspection, the discoloration is confined to the nail plate, the surrounding skin is not swollen, and there is no pus; one cuticle has a small nick. She admits she glued a loose acrylic back on twice and soaked the nails off in water. She has an appointment for a wedding in two hours and asks you to 'cover it with a new set.' Your salon uses nippers, an electric file, and reusable metal implements; files and buffers are porous. The client denies diabetes and says she is healthy.
1. What is the likely cause of the discoloration, and why is applying a new enhancement over it contraindicated?
Read the worked answer
The green-black color under a lifted enhancement is most consistent with a bacterial problem such as Pseudomonas, which thrives in trapped moisture. The history fits: lifted acrylic, glued repairs, and water soaking create a dark, damp space. I cannot diagnose, but the appearance and history are enough to withhold the service. A new enhancement would trap moisture again and could worsen the problem or spread contamination. Filing over the discolored plate could also push bacteria and debris into the surrounding tissue, especially near the cuticle nick. I would not treat it with medication or advise a specific drug, because that is outside my scope. I would refer her to a physician or dermatologist if it spreads, becomes painful, swells, or drains pus, and I would advise keeping the nail dry and uncovered until she has been evaluated.
2. What sanitation steps and scope-of-practice limits apply to the implements and the service area?
Read the worked answer
Any reusable metal implement that contacted the affected nail must be cleaned of debris, rinsed, dried, and then disinfected with an EPA-registered hospital disinfectant according to the label contact time. Porous files, buffers, and any absorbent items that touched the area should be discarded, not reused. The electric file bit must be cleaned and disinfected per manufacturer instructions. The table surface should be cleaned and disinfected, and I would change towels and discard the disposable items. I would wash my hands and wear fresh gloves for any service on other nails. I would not soak the affected hand, apply a new enhancement, or file over the green area. Scope-of-practice limits mean I can recognize and refer, but I cannot diagnose an infection or prescribe treatment.
3. How would you handle her wedding request, and what would you document?
Read the worked answer
I would acknowledge the wedding pressure but keep the boundary: 'I cannot safely put a new set over this nail today.' I could offer to manicure the other nails if I can avoid cross-contamination, but I would not apply product to the affected nail or soak that hand. I would explain that covering it could make it worse and that the discoloration may need to grow out. I would offer a simple polish only if the plate is intact and the physician has cleared it, but not over a lifted or wet area. I would document the visual findings, the client's history of gluing and soaking, the refusal of the full set, the referral advice, and the alternative offered. I would also note that she was told to seek medical evaluation if symptoms change.
