Green Discoloration Under Acrylic and Client-Supplied E-File
A 31-year-old client has a green-black discoloration on the right thumbnail under a lifted acrylic. She has worn acrylics for eight months; her last fill was five weeks ago. There is no pain, but the free edge is lifted and there is a mild odor. She wants a fill and asks you to 'cover the green so it does not show' for a job interview tomorrow. She brings her own electric file with a used carbide bit and asks you to use it because she likes the shape. At your station, the implements from the previous client are sitting in a jar of cloudy blue disinfectant that was mixed yesterday. The salon uses an EPA-registered hospital-grade disinfectant.
1. What is the likely problem, and what is your service decision?
Read the worked answer
The green-black discoloration under a lifted enhancement suggests a bacterial issue, commonly Pseudomonas, especially with lifting, moisture trapped under the acrylic, and a mild odor. A cosmetologist cannot diagnose an infection. Do not cover it with a fill, and do not seal it under a new enhancement; covering traps moisture and bacteria and can make the problem worse. The service decision is to decline the fill, explain what you observe without naming a disease as a certainty, and refer the client to a physician or dermatologist for evaluation.
Removing the acrylic may be appropriate only if the nail plate is intact and the salon's scope allows conservative removal, but if the nail bed is exposed, painful, or the discoloration extends onto the skin, stop and refer. The job interview tomorrow is a real concern, but infection control takes priority. Offer a natural-nail service only after the client is cleared, or suggest a temporary, non-occlusive option if the provider approves. Document the refusal and referral.
2. How do you process the client's bit and your implements, given the cloudy disinfectant?
Read the worked answer
The cloudy disinfectant is not acceptable. Disinfectant becomes contaminated with debris and may lose efficacy; it must be changed according to the label or whenever it is visibly cloudy. Remove the previous client's implements, clean them of debris, and disinfect them properly in fresh solution for the full label contact time. Use test strips if the product requires them, and document the change.
For the client's used carbide bit, do not place it directly into your fresh disinfectant without cleaning it first. Clean the bit with soap and water and a brush, dry it, then disinfect or sterilize it according to the manufacturer's instructions. If the bit is porous, damaged, or cannot be adequately cleaned, do not use it; use your own properly processed bit instead. Client-supplied items are not automatically safe. Wear gloves, avoid touching the green area, and clean the workstation, file handle, and any contaminated surfaces.
3. How do you explain the decision and prevent recurrence?
Read the worked answer
Explain in plain language: 'The green color under the lifted acrylic looks like it could be a bacterial problem, not a stain. I cannot diagnose it, and covering it could trap moisture and make it worse. I recommend you see a physician or dermatologist before I put another enhancement on that nail.' Avoid shaming the client and avoid promising that a fill will hide it safely.
For prevention after clearance, discuss keeping the nail dry, not prying off enhancements, and returning for timely fills before lifting becomes severe. Recommend a new set only after the provider clears the nail. Do not reuse files, buffers, or bits that contacted the area. Document the observation, the refusal, the referral, and the aftercare advice. If the client insists on coverage, repeat the refusal and note it in the record.
