Client With an Allergy After Brow Lamination — Will You Pay Fifty Thousand

Thursday, 4:30 PM. The salon door opens and in walks the client you saw on Tuesday for brow lamination. Her brows are swollen, eyelids red, the skin around her eye flaking off in patches. She looks at you and says in a calm voice: "Give me your OC (Polish professional liability insurance — Odpowiedzialność Cywilna) number, I'm going to the dermatologist, my lawyer is calling tomorrow." At this moment you have ten minutes for decisions that will determine whether you pay one thousand zloty or fifty thousand.

This article is not about how to avoid allergies — because you cannot avoid them entirely. It is about what separates the salons that lose in court from the ones that come out unscathed. Four things make the difference, and all four can be ready before the client arrives — or not, and you explain yourself at the hearing.

Why allergies after brows and lashes happen — a short chemistry course

An allergic reaction after a treatment typically appears 6–72 hours after the skin contacts the product. The client rarely reacts immediately in the chair. Most often she calls the next morning or comes back the day after with swelling.

Typical symptoms of an allergy after salon brow lamination and similar treatments:

• Redness (erythema) in the treatment area, sometimes spreading onto the cheek and eyelid
• Swelling of the upper eyelids — sometimes so severe that the client cannot open her eye
• Skin flaking, weeping vesicles, itching, burning
• In extreme cases an anaphylactic reaction — shortness of breath, throat swelling, drop in blood pressure. That is a life-threatening emergency and an ambulance, not a dermatologist

What specifically causes the allergy:

• PPD and PTD (paraphenylenediamine, paratoluenediamine) in brow dyes and hennas — the strongest contact allergens in the industry, type IV reactions, building up with each subsequent exposure
• Thioglycolates (thioglycolic acid, ammonium salts) in brow lamination and lash lift products — contact allergy plus chemical irritation
• Formaldehyde and cyanoacrylates in lash extension adhesives — strong respiratory allergens, clients sometimes react only at the third or fourth visit
• Parabens and preservatives in fixatives and conditioners — delayed reactions, sometimes up to 7 days after the treatment

Key information that most owners do not know: contact allergy can be cumulative. A client who has had henna with you five times without a problem may walk out after the sixth treatment with swollen eyelids. The argument "but she has been doing this with me for a year" does not work in court, because it does not refute the allergy mechanism.

What the client can do legally — with concrete amounts

A client who walked out of the salon with an allergic reaction has several paths. Each costs you differently.

Path one: civil lawsuit

The basis is article 415 of the KC (Polish Civil Code — Kodeks Cywilny) — liability for damage caused through fault. The client must prove three things: that she suffered damage, that you did something wrong (or failed to do something), and that one follows from the other.

A typical client lawsuit after a treatment covers:

• Treatment costs — private dermatologist visits (300–500 PLN per visit × 3–5 visits), antihistamines and topical steroids, sometimes hospitalisation if the reaction is severe. In total 2 000–5 000 PLN, to be documented with invoices
• Compensation for pain and suffering — the hottest point. Courts currently award between 10 000–50 000 PLN, depending on duration of symptoms, scarring, the impact on the client's professional work, stress
• Refund of the treatment cost — 150–400 PLN, small change, but the client always demands it
• Travel costs to doctors, sometimes rehabilitation costs
• Lost earnings — if the client works in an industry where appearance matters (model, presenter, account manager) and could not go to work for two weeks, she will add the earnings for that period

In practice — the average lawsuit after an allergic reaction in 2026 closes within the range of 15 000–35 000 PLN. The upper brackets (40 000–50 000 PLN) are awarded when there is visible post-inflammatory scarring and when clients have well-documented image damage.

Path two: complaint to UOKiK (Polish Office of Competition and Consumer Protection) and Sanepid

Independently of the lawsuit the client can report the case to UOKiK (Polish Office of Competition and Consumer Protection) (if she claims she was misled about the safety of the service) and to Sanepid (if she claims the treatment was performed unhygienically or without a patch test). Sanepid will arrive within 7–30 days, check the documentation, fine of 200–1 500 PLN plus post-inspection recommendations.

A trend you will not notice until it touches you

In 2025 the number of civil lawsuits against beauty salons after allergic reactions rose in Poland by roughly 40%. High-profile court cases concerning hennas with PPD and allergic contact dermatitis went through the media, clients now know their rights, and law firms specialising in consumer claims are actively looking for such cases.

This is not abstract. This is a change in the environment you work in.

Four things that save you

The court looks at documentation. Not at what you remember, not at what you say now. At paper with a signature and a date.

1. A documented patch test with a negative result

A patch test performed 24–48 hours before the treatment, described in the client card, with date, time, the client's signature and yours. Product name, batch number, application site (most often behind the ear or in the elbow crease), exposure time, result. Without this document you have nothing.

The detailed procedure — when a patch test is mandatory, how to perform it and how to document it — is in a separate post: patch test for brows and lashes — step-by-step procedure.

2. A signed client card with a health interview

A client card with a full interview: allergies known to the client, regular medications (steroids, immunosuppressants, acne drugs), pregnancy and breastfeeding, skin conditions (atopic dermatitis, psoriasis, rosacea), prior reactions to henna or hair dyes. The client fills it in, signs, dates. You keep it in the binder.

How to fill it in correctly — see the client card step by step and the dermatological interview with the client.

3. A treatment procedure with a list of products used

In the binder you have a written procedure: what brow lamination looks like step by step, which products you use (brand, model, batch numbers of the latest delivery), opening dates, expiry dates. Sanepid will ask about this during an inspection. The court will ask about this if the client claims you used an expired product.

4. The stylist's professional liability (OC) insurance

Professional liability (OC) insurance (from 600 to 2 500 PLN per year, depending on the scope and sum insured) typically covers up to 100 000–500 000 PLN of personal damage in a single event. But beware — OC works only if points 1, 2 and 3 are documented. No patch test, no client card with interview, no procedure = the insurer will say: professional misconduct, payment refused. You pay out of your own pocket.

More on how to choose insurance and what specifically to read in the terms: professional liability (OC) insurance for the beauty salon.

The COMPLETE package — 899 PLN gives you the set of three pillars out of four: the client card with interview, treatment procedures for 11 treatments, and the patch test documentation template. The fourth (OC) you order separately from a broker, but with the documents from the package — the insurer has a basis for payment.

Four things that do NOT save you (yet you often hear them)

What no industry conference will tell you, but every lawyer will after the first lost case:

• "The client told me she had no allergies" — without a signature on the card. Word against word, the court looks at the document. The client's oral statement does not exist legally
• "I checked only once, at the first visit" — the health interview must be updated at every change in the client's condition, at least once a year. Allergies appear over time, medications change, pregnancy happens
• "I always use the same product, the client never reacted" — cumulative contact allergy. The court knows this argument and rejects it routinely
• A patch test "by eye", without an entry in the card — if there is no entry in the card with date, the client's signature and the result, legally there was no patch test

Additionally, what does not save you: the client's statement that she "waives the patch test" (legally void), a photo of the patch test on your phone without an entry in the card, nor the fact that the client herself asked for a quick treatment. The salon bears professional liability, the client is a consumer — she does not have to know the procedures, you do.

The first 24 hours after the client's report

The client comes back or calls with swelling. What you do, in what order:

1. Calm and empathy. You say: "I am very sorry this is happening. The most important thing now is for you to go to a dermatologist — I will pay for the first visit." This is not an admission of guilt, it is a gesture of goodwill and adherence to industry standards
2. DO NOT ADMIT fault. Do not say "it's my fault", "I chose the wrong product", "I'm sorry it turned out this way". Say: "I am very sorry you have a reaction, I will check the documentation, I will report it to my insurance." This is not indifference, it is procedure
3. Document everything, immediately. Open the client card, add the date and time of the report, a description of symptoms, your observations. If the client is present — ask for consent for a photo, attach it
4. Advise a dermatologist visit the same day or the next. Offer to pay the invoice — it is a gesture, not an obligation
5. Offer a refund of the treatment cost as a gesture of goodwill. This is not an admission of guilt, it is the standard. Write a statement: "The salon refunds the treatment cost as a gesture of goodwill, without acknowledging liability"
6. Contact OC the same day. Reporting a claim to the insurer typically has a deadline of 7 days. The sooner, the better. You send: the client's details, the date of the treatment, a description of the situation, a copy of the client card, a copy of the patch test, a copy of the procedure
7. Keep all messages from the client — texts, emails, Instagram conversations. Do not delete them. If the client writes "you did this to me, you will pay", that is evidence in the case
8. Do not respond impulsively. If the client escalates on social media, do not enter the comments, do not explain yourself publicly. Hand the case to OC, they have legal advisors

What most often goes wrong in those 24 hours: the owner panics, calls the client ten times, promises "we will fix it", offers in writing a refund of 5 000 PLN "so she does not go to a lawyer" — and that document becomes evidence of an admission of fault. Calm, procedure, OC.

If the client threatens a formal complaint — you have a separate scenario: beauty service complaint — how to respond.

How to build documentation today, not when the lawsuit arrives

The hardest truth of this article: the documentation that will save you in court, you build now, when nothing is happening. Not when the client is standing in the doorway with swelling.

A concrete plan for the next 30 days:

• You implement the client card with a full health interview for every client — new and old. Old clients fill it in at their next visit
• You implement the patch test procedure for all brow, lash and dye treatments. Every patch test has its entry
• You set up a binder with procedures: brow lamination, henna, lash lift, lash extensions. Every procedure has an update date
• You take an inventory of products: list, brand, batch, opening date, expiry date. You update it once a month
• You order professional liability (OC) insurance or check whether your current one covers personal damages up to at least 100 000 PLN

This is one afternoon of work if you have ready-made templates. Three weekends if you do it from scratch.

The COMPLETE package — 899 PLN contains 30 .docx documents: the client card for 11 treatments, patch test procedures, treatment procedures, RODO (Polish GDPR), regulations, complaint templates. You open it in Word, fill in the salon details, print it. Implementation — one afternoon.

FAQ — Frequently asked questions

Does a patch test have to be repeated for every client at every visit?

No. You perform a patch test at the client's first visit for a given treatment. You repeat it if: you changed the product to a different brand or batch, the client reports a new allergy in the interview, the client is pregnant or breastfeeding (hormonal changes), or more than a year has passed since the last patch test. The note "patch test repeated due to X" must be in the card.

What if the client refuses a patch test?

You refuse to perform the treatment. The patch test is a salon sanitary procedure, not the client's wish — and it cannot be "bought out" with a statement. If the client signs "I waive the patch test and any claims", that statement is legally void, because it removes a professional obligation. In case of a reaction the insurer will refuse payment, and the court will not defend you.

Does professional liability (OC) insurance cover everything?

No. OC covers personal (health) and property damage caused by you while performing your profession — up to the sum insured. It does not cover: damage caused intentionally, damage arising from professional misconduct (no patch test, no client card, use of expired product), the client's reputational damage (unless in an extended package), administrative fines from Sanepid. Read the OWU — the general terms and conditions — before you sign.

What if the treatment was performed by a B2B (sole-trader to sole-trader contract) stylist, and the client sues me as the salon?

The cosmetic salon's civil liability runs on two tracks here. The client typically sues the salon (because she has a contract with the salon), and the salon has a recourse claim against the B2B (sole-trader to sole-trader contract) stylist. That is why the B2B contract with the stylist must contain a provision about her own professional liability (OC) insurance and her obligation to follow the salon's procedures. Without that — the salon pays, and enforcement against the stylist is long and uncertain.

How much time do I have from the client's report to gather documents?

Reporting the claim to OC — typically 7 days from the event (check your OWU, some insurers give 14). The client's civil claim becomes time-barred after 3 years from the day she found out about the damage and about who is liable for it. Gather documentation immediately — within the first 24 hours after the report. The longer you delay, the less credible your position looks if it comes to a trial.

The full set of documents that a beauty salon should have ready in case of a client's allergic reaction — client card with interview, patch test procedures, treatment procedures, complaint and response templates — you will find in the NailsReady COMPLETE package (899 PLN, 30 .docx documents). You open it in Word, fill in the salon details, print it, file it in the binder. Implementation — one afternoon, peace of mind — for years.
