Deposits, Rebooking, Reminders & Patch Tests: 5 Questions UK Salon Owners Ask

Run a salon long enough and the same handful of questions come round again and again. Should I take deposits? How do I get people to rebook? Can I legally text a reminder? When does a client really need a patch test? We get asked all five constantly — usually by owners in London and across the UK who want a straight answer, not a sales pitch.

Here are those answers in one place. Whether you run a single chair in Shoreditch or a five-stylist floor in Soho, the rules below are the same.

1. Should I charge booking deposits at my salon?

Yes — if no-shows are costing you more than the awkwardness of asking. Here's the honest maths. A single missed colour appointment can cost you £80–150 in dead chair time. Four no-shows a month is £400+ gone — more than most salons spend on marketing.

A deposit doesn't need to be big to work. Most UK salons that charge one settle on 20–30% of the service price, or a flat £10–20 for shorter appointments. The point isn't the money. It's commitment. A client who has paid £20 upfront turns up.

Three things make deposits work without scaring clients off. First, say it plainly at booking — "we take a small deposit to hold your slot, it comes off your bill." No apology, no essay. Second, make paying it effortless: a payment link at booking, not a bank transfer they'll forget. Third, have a fair cancellation window — 48 hours' notice moves the deposit to a new appointment rather than losing it. Clients accept rules that feel reasonable; they resent rules that feel like traps.

Worried about losing bookings? In practice, the clients deposits filter out are the ones who weren't coming anyway. Your loyal regulars won't blink.

2. How do I get clients to rebook before they leave the salon?

Ask at the basin, not the till. By the time a client is paying, her coat is on and her mind is on the car park. The moment to plant the rebook is mid-treatment, when you're already talking about her hair: "This colour will start pulling warm around week six — shall I pencil you in before it does?" You're not selling an appointment, you're protecting the result she's just paid for.

Three things make this work consistently. Give a reason, not a request — "Want to rebook?" gets "I'll check my diary"; "your balayage needs a gloss in 8 weeks or it'll fade flat" gets a booking. Make it the stylist's job, not reception's — the person who did the work has the authority to recommend the next one. And remove the friction — the slot should be offered, confirmed, and in her phone before she's out the door.

Salons that rebook in-chair typically hold 60–70% of clients to a fixed cycle; those that wait for clients to call back hover nearer 30%.

3. Do I need consent to text clients appointment reminders in the UK?

For a plain reminder — no. For anything that sells — yes. The line between the two is where salons get caught.

A text that says "You're booked with Maria, Thursday 2pm, reply C to confirm" is a service message, not marketing. PECR (the UK rules on electronic messages) doesn't require consent for it, and under UK GDPR you can rely on legitimate interests. The moment you add "...and 20% off colour this month!", the whole message becomes marketing — now you need explicit consent or the soft opt-in (existing client, similar service, told they could opt out at sign-up, opt-out in every message).

Keep reminders boring and the law stays out of your way.

4. How often do clients need a patch test for hair colour in the UK?

More often than most salons do them. There is no single law that says "patch test every 6 months" — what exists is a chain of liability: manufacturer instructions, your insurance policy, and negligence law. Most colour manufacturers (Wella, L'Oréal, Schwarzkopf) instruct a test 48 hours before every application or at minimum before the first and after any break. Your insurer almost certainly requires you to follow those instructions — skip the test, and a reaction claim can void your cover entirely.

The practical standard most UK insurers and the NHBF accept:

• New client: patch test 48 hours before the first colour service. No exceptions, even if "they've had colour for 20 years".
• Returning client: re-test after 6+ months without colour, after any reported reaction (even mild itching), after pregnancy, after a new tattoo or henna, or whenever the product is reformulated.
• Black henna history: treat as high risk. PPD sensitisation from holiday henna is the most common trigger for severe reactions.

The hard part isn't the test — it's remembering who was tested, when, with which product line. A reaction note scribbled on a paper card from 2024 won't protect you. Keep a dated record per client: product, batch where possible, result, and who performed it. An awkward conversation costs you one appointment; an anaphylaxis claim can cost you the business.

5. What's the best salon booking app for clients with allergies?

The best one for allergy-prone clients isn't the one with the prettiest calendar — it's the one that remembers the safety record and surfaces it before the service, not after. Most booking apps treat the allergy field as a box that gets filled in once and never looked at again. That's exactly how reactions slip through.

What to look for: a per-client safety record that travels with the client between visits and stylists; automatic patch-test recall reminders tied to the manufacturer's window; and a flag that shows up at the point of booking, so a colour appointment can't quietly get booked for someone who's overdue a test. That's the gap SAY-OS was built to close — it's the app that remembers everything for you, so the safety conversation happens every time, not just when someone remembers to ask.
