Minors in a Nail and Brow Salon: Consent Procedure and Services to Refuse

A 15-year-old walks in. She wants brow lamination. Her mum is "in the car." You ask yourself: can I go ahead? This is not a question about willingness to earn. It is a question about the civil and criminal liability you take on the moment that client sits in your chair without proper consent documentation.

This article gives you concrete answers: who can be treated, who cannot, which services require parental consent, and how to collect that consent correctly.

Age and Legal Capacity: Three Brackets You Must Know

Polish civil law (Civil Code, Articles 11-22) divides the capacity to enter into contracts by age. Your service is a contract, even when no one says it out loud.

Under 13: No Legal Capacity

A child under 13 cannot independently enter into any contracts. If a child arrives with a grandmother or older sibling who has no legal guardianship document, you do not perform the treatment. You need a parent or legal guardian physically present and signing consent on the spot.

The only exceptions are minor everyday transactions (a snack, a bus ticket). Brow lamination with thioglycolic acid does not fall into that category.

Age 13 to 18: Limited Legal Capacity

A person aged 13 to 18 can enter into minor contracts without parental consent. The issue is that "minor contracts" do not cover beauty treatments involving chemical products that carry a risk of allergic reaction or irritation. For those, you need parental or legal guardian consent.

For low-risk treatments (classic manicure with no chemical products), some salons see clients from age 16 without written parental consent, though usually after an initial arrangement with the parent. That is a risk you take consciously.

18 and Over: Full Capacity, Independent Decision

An adult client decides for herself. Your obligation is the standard consultation, patch test (where required), and client record card.

Which Treatments Require Parental Consent? A Practical List

PPD Brow Tint: YES, Consent and Patch Test Required

PPD (paraphenylenediamine) is a potentially potent allergen. Allergic reactions to PPD can be serious: chemical burns, facial swelling, and in extreme cases anaphylaxis. With a minor client, you need written parental consent and a mandatory patch test with a 48-hour window. Without parental consent and a completed patch test: you do not proceed.

Brow Lamination and Brow Lift: YES, Consent Required

Thioglycolic acid used in brow lamination and brow lift treatments comes into direct contact with the skin. Teenage skin tends to be more sensitive, so the risk of irritation is higher than in adults. Parental consent is essential; a patch test is strongly recommended.

Gel Polish (Hybrid): From 16 Without Consent, Under 16 With a Parent

Gel polish has low systemic toxicity. Most salons have adopted the practice of treating clients from age 16 without written parental consent, ideally with the parent present at least for the first visit. Under 16: parent present or written consent. This is your business decision, but it should be stated clearly in your salon policy.

Lash Extensions: Parental Consent Recommended Under 16

Cyanoacrylate adhesive can trigger allergic reactions: watering eyes, conjunctival redness, eyelid swelling. For clients under 16: written parental consent. Above 16: your call based on your risk assessment and salon guidelines.

Classic Manicure Without Chemical Products: Usually From 14 to 16 Without Consent

Classic manicure (file, regular nail polish, cuticle oil) carries low risk. Most salons treat clients from 14 to 16 after a prior arrangement with the parent or a general parental consent signed at the start of the season. No electric file and no products with allergy risk.

How to Set Up a Minor Client Procedure in Your Salon

Date of Birth on the Client Record Card

Record every client's date of birth. It sounds obvious, but with 30 clients a week it is easy to lose track. A date of birth lets you immediately check whether the minor client procedure applies.

Parental Consent Form

Best practice: the parent signs in person at the salon. The parent comes in for the first visit and signs a form that specifies exactly which treatments they consent to and for what period (for example, "until 30 June 2026").

WhatsApp or SMS consent: carries some evidentiary value, but significantly less than a handwritten signature. If the parent cannot come in, a written message with confirmation and the parent's phone number saved in your records is better than nothing. In a legal dispute you are still at a disadvantage without a paper signature.

When Consent Is Missing: Polite, Firm Refusal

Say: "I need parental consent for this treatment. Please come back with your mum or dad." You do not enter into a discussion about whether the client "looks older." You do not explain yourself further. If she insists, you repeat the sentence. This is not a matter of opinion; it is your procedure.

Salon Liability When Parental Consent Is Missing

Civil Liability

The parents of a minor have the right to seek compensation for harm caused to their child by a beauty treatment. If a 15-year-old develops an allergic reaction after brow lamination performed without parental consent, you face tortious liability. No written consent means no proof that the parent knew and accepted the risk.

The Burden of Proof Works Against You

In a legal dispute, you must prove you had parental consent. Without a document, and with a parent claiming they had no knowledge, that will be very difficult. "She told me she was 18" is a weak defence without any supporting documentation.

Can You Ask for ID?

Yes. You have the right to ask for a document confirming age if you have doubts. A national ID card or school ID card. If the client refuses to show it, you refuse the treatment. That is your right as a business entering into a contract.

FAQ

Is WhatsApp consent legally valid?

It has some evidentiary value, but much lower than a handwritten signature. A WhatsApp message can be deleted, blocked, or its authenticity challenged. If you use electronic consent, save a screenshot with the parent's phone number and name. Written consent signed at the salon is always the safest option.

What if a 17-year-old claims she is an adult?

You can ask for ID. If she refuses to show it, you treat her as a minor and apply the parental consent procedure. If she presents a false document, liability shifts to her (or her parents). In your records you note: "client presented ID, appearance consistent with stated age." That is your safeguard.

Can I ask every client for ID?

You are not required to ask everyone, but you have the right to ask if you have doubts. Record age and date of birth on the client card for every new client. If appearance suggests the client may be a minor, ask for ID. This is standard practice in the beauty industry.

Can I lose my business licence for treating a minor without parental consent?

The State Sanitary Inspectorate will not typically revoke your permit for a single incident. But if a minor suffers a health injury and civil proceedings follow, the financial penalty can be significant. Systematic lack of documentation can also lead to consequences during a comprehensive inspection by the labour inspectorate or sanitary authority.
