How to run a hair colour consultation

The result of a colour service isn't decided at the mixing bowl — it's decided in the consultation. Before you reach for the colour, you need to know what's already on the client's head, what she wants, and what's realistically achievable in one visit. A good consultation is the difference between a happy client who rebooks and a comeback you'll spend half a day fixing for free.

This guide walks through a colour consultation step by step — reading hair history, choosing a shade by skin undertone, managing expectations, the patch and strand tests, transparent pricing and recording the formula in the client card. It's written for stylists who want to colour with confidence and no nasty surprises.

Why the consultation decides the result and the trust

A client isn't buying a shade off a chart — she's buying the feeling that you understand her. When you sit down at the start, look at the hair and ask questions, you're doing two things at once: gathering the information that decides your technique and product, and building the trust that gets your recommendation and your price accepted. A colour consultation is a specialised version of the wider routine covered in the client consultation guide — it just goes deeper into the craft.

A skipped consultation almost always comes back as a problem: colour that isn't what she pictured, disappointment, or even an irritated scalp because you cut the test. A few minutes up front saves you hours of correction later.

Reading the hair history

Colour goes onto what's already in the hair, not onto what you see. So ask before you mix:

• Previous colour. When, which shade and how often. Colour builds up in the hair — the ends may be darker and more saturated.
• Box dye. Home colour often contains metallic salts and behaves unpredictably. An admitted box dye changes your whole approach.
• Henna and plant dyes. Henna doesn't get along with chemical colour or lightener and can react unexpectedly. Always ask about it directly.
• Chemical treatments. Perms, relaxers, keratin or previous bleaching change both the structure and how colour behaves.
• Condition and porosity. Damaged, porous hair takes colour faster and holds tone differently. Feel the hair both dry and wet.

If a client says "I've not done anything to it" but the ends are noticeably dark or cool, trust the hair over the memory. This is exactly where the strand test earns its place.

Skin undertone, eye colour and a realistic shade

The shade that suits isn't the prettiest one in a photo — it's the one that harmonises with the client's skin and eyes. Distinguish a warm and a cool undertone: warm skin usually carries golden, honey and copper tones, cool skin carries ash and cooler tones. Eye colour and natural hair colour fill in what will read as natural.

Offer a shade she can maintain at home and that won't look harsh as it grows out. A realistic, harmonising tone stays looking good longer and pushes her towards fewer corrections — and, tellingly, satisfaction with her colour is one of the pillars of building a loyal hair clientele.

Managing expectations

The most common source of disappointment is the gap between the picture and what the hair can do. Work with reference photos, but read them critically — lighting, filters and the starting colour in the photo all distort.

Explain two terms simply: level is how dark or light a shade is, and tone is the direction of the colour (ash, gold, copper). The client doesn't need the numbers, but she does need to grasp that black to platinum won't happen in one afternoon without damage.

Say openly what's realistic in one visit and what needs several. With bold changes and lifting especially, staging the work is part of the craft — how to plan the time between lightening and toning is covered in the guide to managing colour processing time.

With greys, be specific: how much grey the client has and whether she wants full coverage or a blend. Three-week-old regrowth looks different from fresh colour, and it's fair to say so upfront.

The patch test and the strand test

This isn't a formality — it's safety and your duty of care. Run the patch (allergy) test as the manufacturer directs, typically 48 hours before the service, especially for a new client or after a long gap. A reaction to PPD and other ingredients can be serious, and one tolerated application is no guarantee for the future.

The strand test is done for the result: on a hidden section you check how the hair reacts, how fast it takes tone, and whether the formula or timing needs adjusting. With an unclear history — suspected henna, metallic salts, heavy damage — the strand test is what saves you from a full-head disaster.

Note in the card that the test was done and its outcome — it's also a record that you followed the correct procedure.

Transparent pricing during the consultation

Colour is time plus product, and on bigger transformations both vary from client to client. The worst move is quoting the price at the till. Agree it before you start mixing, so the client knows what she's paying for.

• Explain that price rises with hair length, product amount and number of steps.
• On a multi-stage transformation, give today's price and an estimate of the total.
• If the hair turns out to need more work mid-service, stop and re-agree — never surprise her with the bill.

A clear, pre-agreed price list protects both of you; you'll find an indication of prices and plans on the pricing page. A fair price upfront is cheaper than a comeback afterwards.

Recording the formula in the client card

What you don't write down, you start from scratch next time. Record the whole formula in the client card so the next visit is faster and the result consistent:

• Shades and mixing ratio, developer volume.
• Processing time and any intermediate steps.
• The starting condition, porosity and notes on how it reacted.
• The result and what to adjust next time.

A paper card gets lost; a digital one doesn't. When the formula lives in your system, a colleague covering for you can find it too. Client history is covered in the guide to client cards and history, and the whole hairdressing operation — from bookings to cards — ties together in a booking system for hairdressers. You can try it hands-on by creating a free YourSalon account and keeping your first records on practice data.

Quick consultation checklist

• Ask about the full hair history, not just the last colour.
• Feel the hair dry and wet, assess porosity and condition.
• Establish the skin undertone and offer a harmonising, realistic shade.
• Read the reference photo critically and say what one visit can do.
• Arrange the patch test in time and a strand test for any unclear history.
• Agree and confirm the price before mixing.
• Record the formula, timing and result in the client card.

Common mistakes

• Mixing before asking. An unknown hair history is the fastest route to a comeback.
• Promising the photo regardless of the starting point. Colour-treated dark to platinum isn't an afternoon's work.
• Skipping the test. An allergic reaction is a health and legal issue, not just a cosmetic one.
• Not quoting upfront. A surprise bill destroys trust faster than almost anything.
• Not recording the formula. Next time you're guessing, and the client can tell it isn't the same.

The consultation isn't a delay before the "real work" — it is the real work, the part that decides the result, the price and whether she comes back. A stylist who asks, reads the hair and writes it down colours with confidence and sleeps well.
