Three Nails, Three Decisions
Three clients in one week. Client A has horizontal grooves across all ten nails at the same level on each nail; they appeared about three months after a severe flu with a 104°F fever. Client B has a 4 mm light-to-dark brown band running from cuticle to free edge on the left thumbnail, present about eight months, wider at the cuticle than at the tip; she is sure it is a bruise from a door. Client C has pitting on six nails, an oily yellow spot on the right middle nail with separation from the bed, and a small dark speck under the plate that has not moved in six weeks. None report pain or bleeding. You are a nail technician, not a physician.
1. Triage each client: service, modify, or refer. Justify each decision.

Client A - service normally. Horizontal grooves at the same level on every nail are Beau's lines: a temporary growth arrest from the high fever, with the groove appearing weeks later as the plate grew out. It is a history question, not a treatment question. The grooves grow out; you can buff lightly, keep the nails short, and reassure her without naming a diagnosis as fact.
Client B - refer, do not treat as a bruise. A pigmented band that has been present eight months, is wider at the cuticle, and shows color variation is not how a subungual hematoma behaves - a bruise moves out with growth and resolves. A widening longitudinal band requires dermatologic assessment, including checking the surrounding cuticle and skin for pigment spread. Say what you see and where she should go; do not speculate about cancer, and do not reassure her that it is nothing.
Client C - refer, then decide on service. Pitting plus an oily yellow spot with separation is a pattern that belongs to a skin condition, not to a nail technician's scope. The speck that has not migrated in six weeks is likewise not something to dig at or file away. Decline product over the affected nail, offer a gentle service on the others if the skin is intact, and refer.
2. What exactly do you say to Client B, and what do you deliberately avoid saying or doing?

Say:
- "I'm not qualified to diagnose nails, but a band like this that has been there eight months and is wider at the base is something a dermatologist should look at - not because I think it's serious, but because I can't tell from looking."
- "A bruise usually grows out with the nail and fades. This one hasn't behaved that way, and that's the reason to get it checked."
- Give a timeframe: "in the next few weeks" rather than "whenever."
- Offer to keep her regular appointments on the other nails so she is not being sent away entirely.
Avoid:
- Naming a diagnosis or using the word melanoma.
- "I'm sure it's nothing" - that is a clinical opinion and it can delay care.
- Filing, buffing, or cutting into the band to "see what's under it."
- Applying opaque polish over the whole nail, which hides any change; if she wants polish, discuss it and document the discussion.
- Photographing the nail for your social media, even anonymized, without written permission.
3. How do you document these three and where do you draw your scope line in each case?
Read the worked answer
Documentation, all three, same day: objective description (location, color, size in millimeters, texture, number of nails involved), client statements, service given or declined, referral made and to whom, and that the client was told the observation is not a diagnosis.
Scope line:
- You may observe and describe - color, thickness, separation, pitting, ridges, location.
- You may provide cosmetic care on intact, non-suspicious tissue.
- You may refer - that is a professional duty, not an overstep.
- You may not diagnose, name a disease as fact, treat (no antifungal or other products presented as treatment), probe or scrape a suspicious area, or cover a finding so a physician cannot see it.
Why it matters practically: the client in front of you may see three different technicians at three different salons. Written notes with measurements are the only way anyone knows whether a spot changed. That is also your protection if a client later says "nobody told me."
