Client Consultations, Patch Tests and Consent Forms: A Salon Safety Playbook

Consultations for colour, keratin, facials, waxing and lash tints, the hair-dye skin test Indian labels require, a consent form and what to do in a reaction.

Short answer

Before every hair-colour service, do the skin test the exact product's instructions require and wait the full time: Indian labels carry a 24-hour test, and some manufacturers ask for 48 hours. Pair it with a service-specific consultation, a signed consent form and a written record, and stop and refer to a doctor at the first sign of a reaction.

  • Hair-dye labels in India must carry a caution and test instructions under Rule 37 of the Cosmetics Rules, 2020, and the test is meant for "each and every application".
  • Follow the product's own test time; where it says 48 hours, the 24-hour test on the legal template is not enough.
  • Hair dye must never be used on eyebrows or eyelashes, and the label says so; use only products made for lashes and brows.
  • A signed consent form shows you asked and informed; it doesn't excuse a careless service.
  • In a reaction, stop, rinse, don't treat, and refer to a doctor; swelling of the lips, tongue or throat or trouble breathing means calling 112 at once.

  10. Frequently asked questions

Most salon safety problems don't come from bad technique. They come from a question nobody asked: about last year's reaction, the acne medicine, the black mehendi at a cousin's wedding. A consultation, the right test and a written record catch almost all of them before the bowl is mixed.

Most owners treat the patch test as something regulars can skip and the consent form as a legal shield. Neither is true. This playbook covers what to ask for each service, the skin test Indian hair-dye labels require, when to refuse, a consent form you can copy, and what to do, and not do, when a reaction happens. It is not medical or legal advice: for anything beyond "stop and refer to a doctor", the client needs a doctor and you need a lawyer.

What do Indian rules say about hair dye and patch tests?

Under Rule 37 of the Cosmetics Rules, 2020, hair dyes containing paraphenylenediamine (PPD) or other dyes, colours and pigments must carry a caution on both the inner and outer labels, in English and local languages. It says the product may cause skin irritation, that a preliminary test should first be made according to the accompanying directions, and that it must not be used to dye eyelashes or eyebrows, because that may cause blindness.

Every pack must also carry instructions for the test. The legal template describes cleansing a small area behind the ear or on the inner forearm, applying a little of the dye as prepared for use, letting it dry, and washing it gently after 24 hours. No irritation means no sensitivity is assumed. The template ends: the test should be carried out before each and every application.

Manufacturers can ask for more than the template. Wella, for example, instructs a skin test 48 hours before every application, on the inside of the elbow, with the site left unwashed for those 48 hours, and says the product must not be used if a rash, redness, burning or itching occurs.

How do you run the hair-dye skin test in a salon?

Run it as a booked, recorded mini-appointment, done by trained staff with the exact product, on the site and for the time the product's instructions give.

  1. Check the client's record for any past reaction. If there was one, don't test; the answer is no.
  2. Read the instructions inside the pack you will use for her colour. Note the site, the amount and the waiting time.
  3. Cleanse the site as the instructions say.
  4. Mix a small amount exactly as prepared for use (colour and developer, in the stated ratio) and apply it.
  5. Tell her not to wash, cover or scratch the area for the waiting time, and to message the salon at once if she feels itching, burning or sees redness.
  6. Record the date, time, product, shade and batch number, the staff member and the result due date.
  7. At the colour appointment, ask about the test site before you mix anything, and record the answer.
  8. If anything appeared, don't colour. Advise her to see a doctor before any future colour.

The 48-hour wait changes your booking flow. A walk-in who wants colour today can't safely have it today, so turn the test into a booking: a free five-minute test visit, with the colour appointment fixed for two days later. Most clients accept a salon that is careful; the ones who refuse are the ones you didn't want to colour without a test anyway. How to fill the gap with other services that day is a front-desk skill, covered in the salon SOPs guide.

Patch test or strand test?

They answer different questions, and you often need both. A skin (patch) test checks whether the client reacts to the product. A strand test checks how her hair takes the colour, lightener or chemical: the result, the timing and the condition afterwards. A strand test is essential on hair with a history of mehendi, previous lightening or chemical straightening, where the result can be unpredictable.

What should you ask before each service?

Ask the questions that would change what you do. Every service has a few that matter, and asking all of them every time is what turns a consultation into a safety check.

ServiceMust askTestDon't proceed, postpone or refer if
Hair colour, including "natural" and ammonia-freeAny past reaction to hair dye, black henna tattoos or dark mehendi; scalp cuts, sores or sunburn; recent mehendiSkin test per the pack, every time; strand test if mehendi or past lighteningAny past reaction; a positive skin test; broken or inflamed scalp

Facials, clean-ups, peelsActive skincare (retinoids, acids), recent laser or peel, active acne, rosacea, eczema, cold sores, sunburnPatch test for new or active productsInfection or broken skin on the area; any peel stronger than your supplier's salon-use range
Face bleachSensitivity to bleach before, threading or waxing todayPatch test per the packBroken or freshly threaded skin
Waxing and threadingPrescription acne medicines (tablets or creams), recent sunburn, moles, varicose veins, diabetesWax temperature on your inner wristPrescription acne treatment or a medical condition until her doctor says it's safe
Lash and brow tint, lash liftEye conditions, recent eye surgery, contact lenses, past reaction to tintsSkin test per the tint product's own instructionsAny eye condition; never with ordinary hair dye

Pregnancy, medicines and medical conditions are not things a stylist assesses. The rule is simple and the same for every service: if the answer raises a question, the client checks with her doctor first, and you note it.

Eyebrows and eyelashes are a separate product category

Never use hair dye on eyebrows or eyelashes. The caution on every Indian hair-dye pack says it may cause blindness, and the test instructions repeat that severe inflammation of the eye may result. Use only tints made and labelled for lashes and brows, follow their own skin-test instructions, protect the eye area as they direct, and ask clients to remove contact lenses first.

When should a salon refuse or postpone a service?

Refuse or postpone when a test or an answer shows a risk you can't remove at the chair: a past reaction, a positive skin test, broken or infected skin, an eye condition before a tint, or a medical question only a doctor can answer. A refused service is lost revenue for a day; a reaction can be lost revenue for years.

Postponing a service, at the chair

I'm glad you told me about that. With what you've described, I'm not comfortable doing {service} today, because it could cause a reaction we can't undo. Here's what I'd suggest: check with your doctor, and once they're happy, we'll book you in and I'll do {alternative or follow-up}. Today, I can do {safe alternative} instead, if you'd like.

Never say "it's probably fine" to keep a booking, and never diagnose: "that looks like eczema" is a doctor's sentence, not yours. Say what you saw and why you are stopping.

A consent form should record who the client is, what service and product were agreed, what she was asked and answered, the test and its result, the risks and aftercare she was told about, and two signatures. It is the written version of a good consultation.

Client consultation and consent form

{Salon name}: consultation and consent Client name: {name} Phone: {number} Date: {date} Service: {service} Stylist or therapist: {staff name} Product, shade and batch: {product, shade, batch number} Skin test: done on {date and time}, site {site}, read on {date and time} Result: no reaction / reaction (service not done) Strand test, if done: {result} Health questions (tick yes or no): Past reaction to hair dye, tints or salon products: yes / no Reaction to a black henna tattoo or dark mehendi: yes / no Skin or scalp conditions, cuts or sunburn on the area: yes / no Prescription skin or acne medicines (tablets or creams): yes / no Pregnant or breastfeeding: yes / no Recent chemical services, laser or peels: yes / no Anything else we should know: {details} I confirm that the answers above are correct, that the service, the expected result and its risks have been explained to me, that I have been told what to do if I feel any itching, burning or swelling, and that I agree to the service. Client signature: {signature} Staff signature: {signature}

A signed form shows you asked the right questions and the client understood. It does not make a careless service acceptable, and it can't be used to waive your responsibility for doing the work properly. Keep the language plain and in a language the client reads; a form she can't read proves very little.

How should you keep consultation records?

Keep each client's consultations, test records and consent forms in her client record, retrievable by name and date, for at least two years after her last service. Under the Consumer Protection Act, 2019, a consumer complaint must generally be filed within two years of the cause of action, so a record you have thrown away can't help you answer one.

Health answers are sensitive personal information. Keep paper forms locked away, limit who can open digital records, and don't share them on staff WhatsApp groups. The client data privacy guide covers how to handle client records under the Digital Personal Data Protection Act, 2023.

What should you do if a client has a reaction?

Stop, rinse, don't treat, and refer to a doctor. In an emergency, call 112. Everything else (records, the manufacturer, the complaint) comes after the client is safe.

During the service

  1. Stop the service immediately.
  2. Rinse the hair and scalp, or the skin, thoroughly with plenty of lukewarm water; for hair, a mild shampoo.
  3. Don't apply anything else: no creams, oils, curd, aloe or home remedies.
  4. Don't give any medicine.
  5. If her lips, mouth, tongue or throat swell, her throat feels tight, she struggles to breathe or swallow, or she feels faint, call 112 straight away. Don't let her drive herself.
  6. Otherwise, advise her to see a doctor the same day, and offer to arrange transport.
  7. Keep the product, the bowl and the packaging, and note the batch number.

If she messages after she has gone home

The NHS notes that reactions can take up to 72 hours to appear, so a message the next day is not unusual. Reply within the hour, ask for photos, advise her to see a doctor, and log it.

Replying to a client who reports a reaction

Hi {Client name}, thank you for telling us straight away, and I'm sorry you're going through this. Please don't apply anything else to the area, and see a doctor today. If you can, take the product name with you: it was {product and shade}, batch {batch number}. Could you send us a photo so we can keep a record? I'll call you this evening to check how you are. {Your name}, {Salon name}

Afterwards, flag her record (for example "no PPD-based colour"), report the reaction to the product's manufacturer with the batch number, and review the consultation and test records with the stylist, privately, the same day. Don't sign any statement admitting fault before you have taken legal advice, but don't argue with her either. A client who feels looked after is far less likely to file a complaint than one who feels dismissed.

Can a client complain against a salon in India?

Yes. A salon service is a service under the Consumer Protection Act, 2019, and a client can file a complaint with the District Consumer Disputes Redressal Commission for a "deficiency" in service, which the Act defines to include any fault, imperfection or shortcoming in the quality or manner of a service, including negligence that causes loss or injury. A complaint must generally be filed within two years of the cause of action.

Your best protection is the routine in this playbook, done every time and written down. Three further steps are worth taking:

  • Ask your insurer about cover. A public liability or professional indemnity policy can cover claims from clients; ask what it includes before you need it.
  • Take legal advice early. If you receive a legal notice or a complaint, speak to a lawyer before replying.
  • Don't let the records lapse. The two-year window is why records matter more than memories.

Complaints that never reach that stage are handled in your complaint process, covered in the salon SOPs guide.

How do you train staff on consultations and patch tests?

Train every person who mixes colour or touches skin, sign them off before they consult alone, and refresh it every quarter with role-plays on the questions clients push back on.

When a regular wants to skip the test

I know you've coloured with us for years, and that's exactly why I'm careful. Allergies to hair dye can appear even after many colours without a problem, and the instructions on the pack ask for a test before every application. It takes five minutes today, and I'll book your colour for {day} so it's all ready for you.

The consultation flow also belongs in your hiring trade test: a candidate who mixes colour without asking about allergies has told you how she will treat your clients. See how to hire salon staff.

Frequently asked questions

How long before hair colour should a patch test be done?

Follow the instructions in the exact product you will use. Hair-dye labels in India carry a test that is read after 24 hours, but some manufacturers, such as Wella, instruct a skin test 48 hours before every application. Where documents differ, follow the longer time, and test with the same brand and line you will colour with.

Is a patch test required by law in India?

Rule 37 of the Cosmetics Rules, 2020 requires hair dyes containing PPD or other dyes to carry a caution saying a preliminary test should first be made according to the accompanying directions, and test instructions stating it should be done before each and every application. Following those label instructions is the standard a salon will be judged against if something goes wrong.

Do regular clients need a patch test every time?

Yes. The test instructions on Indian hair-dye labels say the test should be carried out before each and every application, and manufacturers such as Wella instruct a skin test before every application. India's dermatologists' association, IADVL, notes that hair-dye allergy can occur even after years of using the same product, so a regular is not exempt from the risk.

Can you use hair dye on eyebrows or eyelashes?

No. Every hair dye sold in India must carry a caution that it should not be used for dyeing eyelashes or eyebrows because it may cause blindness, and its instructions warn of severe inflammation of the eye. Use only tints made and labelled for lashes and brows, and follow their own skin-test instructions.

What should a salon consent form include?

Include the client's details, the service, product, shade and batch number, the skin-test date, site and result, answers to health questions such as past reactions, skin conditions, prescription skin medicines and pregnancy, a statement that the result, risks and aftercare were explained, and signatures from the client and the staff member. Keep it with her client record.

What should a salon do if a client has an allergic reaction to hair dye?

Stop the service, rinse the hair and scalp thoroughly with lukewarm water and a mild shampoo, apply nothing else and give no medicine, and advise her to see a doctor the same day. If her lips, tongue or throat swell or she struggles to breathe, call 112 immediately. Keep the product and batch number, and record everything.

Can a client take a salon to consumer court in India?

Yes. Under the Consumer Protection Act, 2019, a client can complain to the District Consumer Disputes Redressal Commission about a deficiency in service, which includes negligence that causes loss or injury, generally within two years of the cause of action. Keep consultation and test records for at least two years after a client's last service, and take legal advice before replying to a notice.

What is the difference between a patch test and a strand test?

A patch or skin test checks whether a client's skin reacts to a product, and must be done before every colour service as the product instructs. A strand test checks how her hair takes the colour, lightener or chemical: the result, timing and condition. Hair with mehendi, previous lightening or chemical straightening needs both.
