How to handle a client who has lice or a contagious condition as a solo beauty pro
The service has started. You are at the scalp, or at the eyes, or at the fingertips, and you see something that was not on the intake form. Lice. A fungal patch near the hairline. An active cold sore at the lip crease. Nail discoloration that is unmistakably onychomycosis. In the next five seconds you have to process what you are seeing, decide whether it is what you think it is, and figure out how to stop the service without making the client feel humiliated, accused, or like she was deliberately deceiving you — because in most cases she was not.
This is one of the situations in solo beauty where the right answer and the socially comfortable answer are furthest apart. The right answer is to stop. The socially comfortable answer is to finish as planned and hope for the best. The second option contaminates your tools, puts your next client at risk, and puts you in a position where you cannot defend your professional standards if the situation surfaces later.
Most clients with lice do not know they have lice. Most clients with early tinea capitis think they have dandruff. Many clients with nail fungus have had it so long they assume it is a bruise or water damage. The client who arrives with an active cold sore may have one at the same time every month and has simply learned to work around it in her own life. These are not primarily situations of concealment. They are situations of unawareness or normalization, which means your tone is the deciding variable between a client who feels cared for and rebooks and a client who feels humiliated and disappears.
The wrong response is either extreme: pressing through and pretending you did not see it, or stopping in a way that reads as accusation. The right response stops the service cleanly, names what you saw with professional neutrality, and gives the client a clear path to rebooking after the condition is addressed. When done well, many clients describe the conversation as one of the most professional interactions they have had.
Why this situation is distinct from related ones
This is not the same as the client who shows up visibly sick with a respiratory illness. A client with a runny nose, fever, or cough is detectable at the door, before the service starts. You can make the decision to pause or reschedule before your tools are deployed and before sustained contact has begun. With a contagious skin, scalp, or nail condition, you often cannot see anything until you are already working: you need to be at the scalp sectioning the hair to see lice, at the nail bed prepping the surface to see fungal discoloration, at the lip crease preparing the treatment area to notice the cold sore. The timing is different, and the stakes shift accordingly — stopping mid-service is a harder ask than rescheduling at the door, and the scripts are different.
This is also distinct from the client who has a medical condition that affects how you deliver the service. A pregnancy, a recent surgery, or a skin sensitivity is a condition you adapt around — you modify technique, use different products, or adjust the approach. A contagious condition is not something to adapt around; it is something that requires stopping, because completing the service risks spreading it to your tools, your equipment, your workspace, and your next client. The response is structurally different.
It is also distinct from the client who has an allergic reaction to your products during the appointment. An allergic reaction is a response to something you introduced. A contagious condition is pre-existing and unrelated to what you are using. The response protocol, the liability concern, and the follow-up conversation are all different.
Three types of contagious condition
Type One: Scalp and hair conditions
Lice and tinea capitis (scalp ringworm) are the two most common scalp conditions a solo beauty pro will encounter, and they are the ones that provoke the strongest fear response because both involve sustained proximity at the scalp during services that are often 60 to 180 minutes long.
Lice are most commonly encountered in clients who have young children in school or are otherwise in close contact with school-age children. The client very often does not know she has them — adult lice are small, move quickly, and the most common symptom (scalp itch) is nonspecific. She may have been scratching and assuming dry scalp for weeks. Finding them during a service is genuinely news to most clients, not a revealed secret.
Tinea capitis presents differently: patchy hair loss, scalp scaling that looks like dandruff, sometimes a raised, crusted patch called a kerion. It is less common in adults than in children but not rare. Many clients with early tinea capitis have been treating it as dandruff or seborrheic dermatitis and do not recognize the distinction. It is contagious through direct contact and through shared tools.
Type Two: Skin conditions at the service area
This type is most relevant to lash artists, brow artists, PMU artists, and any pro whose work brings tools into close proximity with the lips, eyes, or face. The most common condition in this category is an active HSV-1 cold sore outbreak, which typically presents as a tingling or visible blister at the lip corner or vermilion border. It is extremely common — roughly two-thirds of adults carry HSV-1 — and the majority of clients who get cold sores have had them often enough that they have normalized them. Many do not think to disclose them because they do not think of them as relevant to a lash or brow appointment. They often are.
Other Type Two conditions include impetigo (a bacterial infection that produces honey-colored crusting, most often on the face), and any open skin infection or wound in the service area. These are less common than HSV-1 but require the same response: the service cannot proceed in the affected zone until the condition is resolved.
Type Three: Nail and hand conditions
Onychomycosis (nail fungus) is the most common nail condition in the adult population — estimates suggest it affects 10–14% of adults, with higher rates in older clients. A significant proportion of clients with nail fungus have had it for long enough that they have normalized it: they assume the discoloration is from old polish, water damage, or something they did years ago. Many are genuinely unaware that it is a fungal infection.
Onychomycosis presents as thickened, discolored nails — yellow, white, or brownish — with possible separation of the nail from the bed (onycholysis). A nail technician performing prep work will usually encounter it before the manicure begins. The “greenie” (pseudomonas bacterial infection, presenting as a green or blue-green patch under a lifting artificial nail) is a Type Three condition specific to nail enhancement clients. Paronychia — a bacterial infection of the skin around the nail — is another Type Three scenario that presents as redness, swelling, and sometimes discharge at the nail fold.
Working on a nail with active fungal or bacterial infection spreads the organism to your implements, files, and buffers. Because these tools are used on the next client, the cross-contamination risk is not theoretical. It is the mechanism by which nail fungus spreads in salon settings and is the primary contamination risk in the nail vertical.
Five scripts
Script 1: The mid-service stop for Type One (scalp/hair)
When you discover lice or a scalp condition while working at the hairline or scalp, stop the service at the earliest natural pause point. Put down your tools, remove your gloves if you are wearing them, and address it directly.
“I want to stop for a moment — while I was working at your scalp I noticed something I need to check on. It looks like there may be lice in the hair near your crown. I know this is not what either of us expected — this happens, and most of the time people genuinely don’t know. I can’t continue the service today because of the risk to my tools and my other clients, but I want to help you figure out next steps and get you rebooked once it’s treated. Can I show you what I’m seeing?”
Several elements of this script matter. Naming what you saw rather than asking if she knows she has it removes the ambiguity while preserving her dignity. Saying “I know this is not what either of us expected” puts you both on the same side of a situation rather than you on one side and her on the other. Offering to show her what you are seeing invites her into the information rather than delivering a verdict she cannot see or respond to. And ending with a path to rebooking converts the stop from a rejection into a temporary pause.
Adapt the middle clause for tinea capitis: “...I noticed a patch near your scalp that looks like it could be a scalp condition rather than dandruff — it may be worth seeing a dermatologist before your next service.” You are not diagnosing; you are describing what you see and recommending professional evaluation.
Script 2: The pre-start notice (when you see it during consultation)
When the condition is visible before your tools are deployed — during the cape-and-consultation phase, or at the start of the wet check before color application — the conversation is significantly easier because nothing has been started and no contamination has occurred.
“Before we get started, I noticed something at your hairline I want to mention — it looks like there may be lice in this area. I can’t do the service today because of what it would mean for my tools and the clients after you, but I want to point you toward what to do next and get you back in as soon as it’s resolved. Can I show you what I’m seeing?”
The tone is the same — neutral, informative, action-oriented — but the urgency is lower because nothing has started. The rebooking path is the same. Many clients discovered at the pre-start stage are relieved to have been told before the appointment began, because it means no service fees have been incurred for something they could not have known was going to prevent the service.
Script 3: The skin-condition stop for Type Two (cold sore / HSV)
For lash artists and PMU artists, the cold sore script is the most commonly needed Type Two script. Adapt the phrasing for the service zone.
“I want to check in before we start applying — I can see there’s an active cold sore at the corner of your lip. For lash/brow work this close to the eye and lip area, I can’t do the service while it’s active because of the risk of spreading the infection during application. This is a really common thing and I know it’s frustrating to reschedule — once it’s fully healed, we’re good to go. When do you think it’ll be resolved? I’ll hold a slot for you.”
For PMU artists doing lip blush, the stakes are higher and the script should be more explicit: “For lip blush specifically, working over an active cold sore would be a real concern — the process opens the skin and working near active HSV can trigger a severe outbreak. I need the area fully healed before I can do a lip service. I know this is a bigger deal with a PMU appointment — I’m going to hold your spot and we’ll get you in as soon as you’re healed.”
Script 4: The nail-condition stop for Type Three
The nail technician discovering fungal or bacterial nail conditions has a slightly different dynamic: the client is often sitting down, hands on the table, with the expectation that the service is about to begin. The stop needs to happen before any tool has touched the affected nail.
“I want to mention something before we start — I can see some discoloration and thickening on a couple of your nails that looks like it could be nail fungus. A lot of people don’t realize what it is at first — it can look like water damage or old polish for a long time. I can’t do the service on those nails today because my tools would pick it up and I can’t risk transferring it. The good news is a dermatologist or podiatrist can prescribe something that clears it up, and once it’s treated I’d love to have you back in. Can I do the nails that look healthy today, or would you prefer to reschedule for when they’re all clear?”
The final sentence does two useful things: it gives the client agency rather than a single outcome, and it makes the conversation about problem-solving rather than refusal. Some clients will want to proceed on the healthy nails; others will want to reschedule the whole appointment. Both outcomes are fine and both preserve the relationship better than a one-option stop.
Script 5: The rebooking conversion
Every stopped appointment should end with a rebooking path, offered before the client leaves or reaches her car. The tone of the stop determines whether she takes it.
“Once it’s treated, I’d love to have you back in. What I usually ask is a quick note or photo once you’re cleared so I know we’re good to go, and then I’ll get you scheduled. There’s no pressure on timing — I just want to make sure your experience when you come back is exactly what it should be.”
Asking for a “cleared” confirmation before the rebook protects you from a second discovery at the next appointment. It does not require a doctor’s note; a text message saying she’s been treated and is clear is sufficient for most conditions. For lice specifically, “treated and re-checked clean” is the right threshold. For nail fungus, “confirmed treatment underway and affected nails looking healthier” is reasonable.
Five mistakes
Mistake 1: Completing the service anyway
The most common error. The service is in progress, stopping is awkward, the client seems nice, and the reasoning goes: “I’ll just be careful and it’ll be fine.” This is wrong on two levels.
First, it is not fine. Your tools — combs, clips, scissors, nail files, lash tweezers, cape, chair headrest — are now contaminated. Decontaminating every item after the appointment requires time and proper protocol. If you do not decontaminate properly, the next client is at risk. If you do decontaminate properly, you have just doubled your post-appointment time and increased your supply cost for that session.
Second, the client is not served by you completing the service. She leaves with a condition she needs treatment for, which she may not know about if you said nothing. You have delayed the information she needs to address it.
Mistake 2: Treating the client as if she was concealing the condition intentionally
The language you use in the first thirty seconds sets the entire frame. “Did you know you had this?” is an accusatory question. “Why didn’t you tell me?” is worse. Both assume concealment and put the client on the defensive before you have established that she even knew.
Most clients with lice do not know they have lice. Most clients with nail fungus have had it so long they assume it is normal. Most clients with cold sores did not connect their lip condition to the lash appointment they booked three weeks ago. The default assumption should be unawareness, not deception — because it is accurate in the majority of cases, and because it produces a better outcome for the client relationship even in the minority of cases where she did know.
Mistake 3: Not decontaminating properly after the appointment
If you discover the condition early enough that minimal contact was made, the decontamination burden is lower. If you discover it after extended contact, or if you completed the service before deciding to address it, decontamination is non-negotiable.
For lice: capes, towels, and anything fabric that touched the client should be washed at high heat before reuse. Metal tools should be fully disinfected. Brushes, combs, and any tool that touched the scalp should be considered contaminated. The chair headrest cover should be replaced. This is not an exhaustive protocol — your state board will have a specific standard for your license category — but those are the categories.
For nail fungus: files, buffers, and any disposable item that touched the affected nail should be discarded. Metal implements that touched the nail should be disinfected to your board’s standard. The same applies for greenie (pseudomonas): anything that contacted the affected nail is contaminated.
Mistake 4: Having no clear policy on the stopped-appointment charge
This is a billing question that most solo pros have not thought through before it happens, and having no clear answer in the moment is awkward. The three options are: charge for the time used before stopping (if any meaningful portion of the service was completed), offer a partial credit toward the rebook, or waive the charge entirely. Any of the three can be right depending on how far into the service the stop occurred.
What is not workable is deciding arbitrarily case by case based on how you feel in the moment. Write the policy before you need it: if a service is stopped before [X point], no charge; if stopped after [X point], [Y outcome]. Include this in your service policies so that if a client asks, you are stating a policy rather than making it up. A clear policy that errs on the side of the client — no charge or a credit toward rebook — is also the fastest path to converting the stopped appointment into a rebook.
Mistake 5: Not updating the intake form after the first occurrence
If you have never had a client arrive with lice, you probably do not have a scalp condition question on your intake form. After the first time it happens, you should. The intake form question does not prevent the client who does not know she has lice from booking — she cannot disclose what she does not know. But it catches the client who does know, creates a record that you asked, and introduces the topic early enough that the appointment-day conversation is less of a shock.
Adding “do you currently have any active skin, scalp, or nail conditions?” to your pre-appointment questions takes thirty seconds. The client who says yes gives you information you need before she arrives. The client who says no has made a disclosure you have documented. The conversation that follows a discovery is much easier when you can say “I did ask this on the intake form — it’s possible it developed recently” than when you have no record of having asked at all.
Vertical-specific notes
Colorists
Scalp work during color services puts you in direct contact with the scalp for an extended period. Gloves are standard during application and reduce risk, but they do not eliminate it — lice can transfer to capes, the chair, sectioning clips, and tail combs. Tinea capitis is the more insidious condition for colorists because it can look like chronic dandruff or early hair loss for months before the fungal origin is apparent.
A professional habit that helps: during the shampoo or wet-check phase, before any tools are committed, take a few seconds to look at the scalp from multiple sections. This is a natural part of a scalp assessment and does not require explaining. For colorists doing root-to-tip services, this check should be standard. Lice are most commonly found near the nape and behind the ears; tinea capitis typically presents at the crown or hairline.
Colorists are more likely to encounter lice than most other beauty verticals because the demographic of their client base (particularly mothers of school-age children) overlaps with the highest lice-exposure group. Having the script ready is not pessimism; it is professional preparation.
Lash artists
Active HSV-1 cold sore is the primary contagious condition concern for lash artists. The periocular and perioral zones are both in the working area for a full-set application, and adhesive fumes near an active lesion create both a contamination risk and a client comfort concern. Many lash artists include a cold sore question in their intake form; those who do not should add it.
The key distinction for lash work: a cold sore that is fully healed and no longer active is not a contraindication. The question is whether the outbreak is current and active. A client who had a cold sore last week and it has fully crusted and resolved is generally fine for lash work; a client whose cold sore is weeping, tingling, or actively visible at the lip border is not.
Lash artists should also be aware that some clients will mention they “get cold sores sometimes” without connecting this to the day of the appointment. The intake question should specify: “do you have an active cold sore or HSV outbreak today?” rather than a general history question. A general history question produces more information but does not address the current appointment day.
Nail technicians
Nail fungus is the most professionally important contagious condition in the nail vertical, and it is also the most commonly mishandled. The temptation is to work around the affected nails — to do the others and skip the ones with visible discoloration. This creates a partial service with no clear billing outcome and leaves the infected nails in contact with the same tools that then touch the healthy nails. The correct approach is to stop, name what you see, and give the client a clear referral path.
“Greenie” situations in nail enhancement clients are often discovered when a lifted artificial nail is removed at a fill appointment. The pseudomonas infection presents as a dark green or blue-green stain on the natural nail. This is not the same as nail fungus, requires different treatment, and is also a stop-service situation for the affected nail. Some nail technicians include a pre-fill photo check in their confirmation message so that clients who notice unusual color or lifting contact them before coming in. This does not catch everything but it catches some situations before they arrive at the table.
PMU artists
The cold sore policy is more consequential for PMU artists than for any other vertical because lip blush involves opening the skin in the lip area. Performing lip PMU over an active HSV-1 outbreak can trigger a severe, prolonged outbreak and significantly impair healing. This is not a minor risk; it is a documented complication with real consequences for the client.
Many PMU artists require antiviral pretreatment (prescribed by a physician) for all clients with known HSV-1 history before lip PMU. If you are performing lip work, your intake form should ask explicitly about cold sore history, and your policy should require that clients with known HSV history discuss antiviral coverage with their doctor before their appointment. This is a medical-adjacent disclosure, not an unusual one, and most clients who have been managing cold sores for years appreciate the thoroughness.
For PMU artists, the cold sore policy is worth explaining at the consultation, not just on the intake form, so that it is understood before the deposit is paid and the appointment date is set. A client who discovers on appointment day that she cannot have her lip blush because of an active cold sore is significantly more frustrated than a client who knew the policy when she booked and planned around it.
Mobile groomers
The equivalent contagious conditions for mobile groomers are sarcoptic mange, ringworm (tinea corporis from animal contact — notably, ringworm from animals is zoonotic and can transfer to humans), and cheyletiella (“walking dandruff”). These are all discoverable during the pre-groom assessment and should be handled before the service begins rather than mid-groom.
A pre-groom skin check is standard professional practice and gives you a natural opening to name what you are seeing: “I’m going to do a quick skin and coat check before we start — I want to make sure there’s nothing that would affect the service.” This frames the check as routine care rather than suspicion, and makes the conversation natural if you find something.
Mobile groomers working in the client’s home are in a particularly exposed position because there is no separation between the grooming environment and the pet’s living space. Protective gloves and appropriate PPE are more important in this context, not less. The owner’s pre-booking intake should include a question about recent veterinary visits and any diagnosed skin conditions, even if the booking is a routine maintenance groom.
The three-year compound
Two nail technicians with similar client volumes and similar service menus. Both operate out of single-station suites and see approximately sixty clients per month.
Nail Tech A encounters nail fungus on three clients in Year One. She says nothing and continues the service each time, telling herself she will be careful with tool cleaning afterward. Her cleaning protocol is adequate but not comprehensive — she disinfects the metal implements but continues to use the same files and buffers on subsequent clients because she does not recognize that they need to be discarded. By mid-Year Two, a regular client mentions that two of her nails look discolored — a presentation consistent with nail fungus. The client does not connect it to her appointments; Tech A does not say anything. The client notices again three months later and mentions it to a friend who suggests the salon may be the source. The friend knows Tech A. The client switches to another provider. Tech A loses one long-term client and a referral line she cannot trace. She has no documentation of the Year One decisions and no way to evaluate what happened.
Nail Tech B encounters nail fungus on three clients in Year One. She stops the service each time, names what she sees using Script 4, refers each client to a dermatologist or podiatrist with a simple card, and offers to rebook after treatment is confirmed. The first client is surprised and slightly embarrassed; Tech B’s tone is neutral enough that the embarrassment does not become the lasting impression. The client sees a podiatrist, texts Tech B that she’s been treated after six weeks, and rebooks. She tells two friends that her nail tech caught something her doctor had missed for years and refused to work until it was addressed. The second and third clients follow similar arcs — one takes four months, one takes two. All three are regulars through Year Three.
By Year Three, Tech B has zero contamination incidents and a reputation in her client base for stringent professional standards. The three stopped appointments, which felt awkward in the moment, are the source of three long-term rebook relationships and word-of-mouth that Tech A does not have. Tech A has lost at least one client to an incident she cannot explain and carries an unresolved awareness that her tool protocol has gaps. The difference between them is not technical skill. It is what they did in a five-minute conversation in Year One.
The booking-flow connection
The intake form question is worth more than the mid-service script. The mid-service script is what you need when the intake form failed to catch the condition. But the intake form question — “do you have any active skin, scalp, or nail conditions you’d like to make us aware of?” — catches the clients who know. The client who knows she has nail fungus and sees the question on the intake form will often disclose it, because the question frames the disclosure as expected and professional rather than shameful.
A client who discloses before the appointment gives you the option to contact her ahead of time, discuss the situation with minimal stakes, and agree on next steps before she has traveled to your location, paid for parking, and sat down at the station. That conversation costs neither of you anything. The in-chair version costs both of you time, discomfort, and the effort of navigating an unexpected stop.
ChairHold’s booking notes field lets you include a custom pre-appointment question in every booking confirmation. Adding the skin and scalp condition question to your confirmation takes thirty seconds to set up. It will not catch the client who does not know she has lice — nothing will — but it will catch the clients who do know, and it creates a documented record of the inquiry for every appointment. When the in-chair conversation does happen, that record changes the framing from “why did you not tell me?” to “I did ask on the intake form — it’s possible this developed after you filled it out.” That is a better conversation. It is also a fairer one.
