Why a returning client is cheaper than a new one
You will read everywhere that a new client costs 5 to 7 times what an existing one does. The figure is usually credited to Bain or to Harvard, and it appears in neither. We went looking for it and came up empty: there is no study behind the number, it has simply been handed from blog to blog for decades. Use it as a rule of thumb if you like, but not as evidence, and do not set a budget by it.
There is a real study, and it is older than you would expect. Frederick Reichheld and Earl Sasser published "Zero Defections: Quality Comes to Services" in Harvard Business Review in 1990. They looked at what happens when a company cuts its customer defection rate by 5 percent, and found something different per sector: 85 percent more profit in a network of bank branches, 50 percent at an insurance brokerage, 30 percent at an auto service chain. Source: Reichheld and Sasser, Harvard Business Review, September-October 1990. The familiar summary that "5 percent better retention lifts profit by 25 to 95 percent" is a later rounding of exactly those three numbers, not a law.
For a salon the percentage says little, since none of those three sectors is a hair salon. The direction is usable though: the return on retention varies by type of business and usually lands higher than people assume. So run the sum on your own business rather than on a number from a blog. If a new client through a Google Ad costs you 25 EUR, and a message to a lapsed one costs you five minutes, you know enough without needing a study.
Three reasons why existing clients return more cheaply:
They already know your salon. No threshold to consider, no uncertainty about quality, no new location to find. One message is often enough, no full persuasion campaign.
You already have their contact details. No ads hoping for a click. Direct contact via email, SMS, or phone. Personal, not anonymous.
They often convert at the same or higher level than before. An existing client rarely books below their previous spend. They often book slightly more expensive because they now have more experience with what they want.
Yet this lever often stays idle. Salons invest in new clients through advertising without ever counting how many people already on their own list have stopped coming. Do that count once: sort your client base by last visit and tally how many have been away longer than 90 days while normally returning within six weeks. What comes out varies so much per business that a percentage would be worthless here, but the number is almost always higher than the owner expected. That is demand you already paid to acquire.
The sum only flips the other way when you have no list yet. On day one there is nothing to win back, and it comes down to local visibility and a diary that is bookable from the start: that is the subject of landing the first clients for a new salon.
First segment: not every lapser is the same
Before you start communicating, segment your inactive clients. Not all lapsers respond to the same message. Four segments that work in most salons:
Warm lapser: recently booked but no follow-up. Client came 4 to 8 weeks ago, would normally rebook now, but you have not seen anything. Often forgetfulness, sometimes a short delay. Low threshold to bring back, a friendly reminder is usually enough.
Lukewarm lapser: 60 to 90 days since last visit. Skipped one normal cycle. Often something came up (busyness, vacation, other priority) or the client is trying someone else. A reason helps: a season change, a new treatment, a personal note.
Cold lapser: 6 months or longer. Client is structurally gone. Possibly moved, possibly switched to another salon, possibly just forgot you exist. Low expectation of success, but a good direct ask sometimes works surprisingly well.
Ex-client: explicit goodbye or seasonal. Client has explicitly indicated they will not return, or only comes for specific occasions (wedding, event). Do not actively try to bring back, do let them know you are still there.
Track these segments in your client base with simple tags or categories. A good client management system lets you filter on last-visit date, preferred staff member, and treatment history. Without that filter you work blind.
When is a client actually late? That depends on the treatment
The 30-60-90 schedule below comes out of the hair world and assumes a cycle of six to eight weeks. For a good part of your client base that is simply wrong, and then you reach out at the wrong moment.
In September 2026 we wrote down what Dutch salons publish themselves as a recommended interval: 26 separate pieces of advice across 24 businesses in 22 cities, plus a separate sample among pedicure practices. Convert those intervals into lapse moments and you land anywhere between four weeks and just over nine months. The rule I use for that is deliberately simple: late from one week past the upper bound of the advice, one cycle missed at twice that upper bound, structurally gone at three times. The days in the table count from the last visit, which is exactly the field you sort on.
| Treatment | Recommended interval | Late from | One cycle missed | Structurally gone |
|---|---|---|---|---|
| Gel polish | 2 to 3 weeks | 28 days | 42 days | 63 days |
| Acrylic or gel infill | 2 to 3 weeks | 28 days | 42 days | 63 days |
| Lash extension refill | 2 to 3 weeks | 28 days | 42 days | 63 days |
| BIAB or builder gel | 3 to 4 weeks | 35 days | 56 days | 84 days |
| Men's cut, short style | 3 to 4 weeks | 35 days | 56 days | 84 days |
| Women's cut, short style | 4 to 6 weeks | 49 days | 84 days | 126 days |
| Facial | 4 to 6 weeks | 49 days | 84 days | 126 days |
| Brow wax or thread | 3 to 6 weeks | 49 days | 84 days | 126 days |
| Colour, gloss | 6 to 8 weeks | 63 days | 112 days | 168 days |
| Brow lift | 6 to 8 weeks | 63 days | 112 days | 168 days |
| Pedicure | 6 weeks, spread 4 to 8 | 63 days | 112 days | 168 days |
| Women's cut, long hair | 8 to 12 weeks | 91 days | 168 days | 252 days |
| Highlights or balayage | 10 to 14 weeks | 105 days | 196 days | 294 days |
Recommended intervals from our own sample of 2026-09-10 among Dutch salons, plus the hair advice from the same round. The three lapse columns are an arithmetic rule applied to those intervals, not measured behaviour.
What jumps out: a gel polish client has already missed a full cycle at six weeks, while the standard 60-day message has not even gone out yet. The other way around, a balayage client is still comfortably inside her normal rhythm on day 30, and a reminder at that point reads as pushing. So the schedule below only works once you shift the days per treatment. How those intervals were collected, and where the sources contradict each other, is in how often clients return per treatment.
Day 30: the soft reminder
The first contact moment is information, not a sales pitch. Goal: remind the client you exist and that their appointment cycle is due for a next one.
When: 30 days after last appointment, for clients with a 4 to 6 week cycle (hair salon, cut). For longer cycles it shifts to 45 or 60 days.
Channel: SMS or messaging. Short, personal, not pushy.
Example copy:
Hi [name], your last appointment with us was [date]. Want to schedule the next one already? [link to booking page]. Best, [salon name].
What works:
- Personal first-name greeting
- Concrete date of last visit (shows you remember them)
- Direct link to book, no detour
- No discount, no offer, no drama
What does NOT work:
- "We miss you" (too emotional for a cut)
- "Special offer just for you" (teaches clients that lapsing earns discount)
- Long paragraph (SMS is short medium)
- No link (client should not have to hunt for your URL)
What you measure: how many warm lapsers book within 7 days. There is no Dutch industry figure to hold yourself against, so your first round is the baseline and only the second tells you whether the message got better.
Frequency: Once. No reminder on the reminder, that is annoying. If someone does not respond, they move to day 60.
Day 60: the reason
Second contact moment, for clients who did not respond on day 30 or came in longer ago. Here you add a credible reason.
When: 60 days after last appointment.
Channel: Email. Long enough for context, more personal than SMS.
Credible reasons (pick one):
Season change. "Summer is around the corner, time for a fresh cut." Works surprisingly well in spring and autumn, less in mid-winter.
New treatment or service. "We recently added a new scalp treatment, ideal if the scalp needs some attention." Authentic only if you actually have something new.
Personal note. "Last time we talked about your trip to Spain, how was it?" Only works if you actually noted these details in the client file.
Practical heads-up. "Busy period is coming, if you want to book again we recommend picking a date soon." Works just before holidays or summer.
Example copy:
Hi [name],
Your last appointment was [date]. Summer is around the corner and many clients are booking their pre-vacation cut now. Do you have a moment for a follow-up?
You can book directly via [link]. No rush, just letting you know we are here.
Best, [staff name], [salon name]
What works:
- Personal sender (not "team of [salon]," real name)
- Concrete credible reason
- No pressure, no deadline, no "within 48 hours"
- Option to do nothing ("no rush")
What you measure: how many lukewarm lapsers respond within 14 days. Expect less than at day 30, because this group has been away longer and the threshold is higher.
Frequency: Once. No follow-up email if response is silent.
Day 90: the direct ask
Third and final contact moment. For clients who did not respond on day 30 and 60. Here you flip the approach: instead of offering, you honestly ask why they are not coming back.
When: 90 days after last appointment.
Channel: Email or (for high-value clients) a personal phone call.
Goal: Not primarily to land a booking, primarily to collect feedback and keep the relationship open. The booking is a byproduct, not the goal.
Example copy (email):
Hi [name],
We have not seen you for a while and want to ask if there is anything we could improve. No sales pitch, just genuine interest. Was there anything about your last appointment that could have been better? Does the scheduling no longer fit, or is it something else?
A short reply helps us, and we genuinely appreciate it.
Best, [owner name], [salon name]
PS: If you would like to come by again, you know where to find us via [link].
What works:
- Honest question, not a disguised offer
- Short text, easy to reply to
- Sender is ideally the owner or a senior staff member (weight in the question)
- PS at the end with option, not as the main point
What you measure: how many people reply with a reason, and how many of those book anyway. Count those two separately, because an honest answer about why someone stopped coming is worth having on its own, even when that client does not return.
Frequency: Once. After this you stop active contact. The client has heard from you three times, that is enough.
If you do give a discount, here is what the law says
Above sets out why a discount should rarely be your first move. If you go for one in the final phase anyway, there are rules attached that most salon articles skip.
The main one is about the price you compare against. Since 1 January 2023, article 5a of the Dutch Besluit prijsaanduiding producten reads: "Bij aankondigingen van prijsverminderingen geeft de verkoper de laagste verkoopprijs aan die door hem is toegepast gedurende een periode die niet korter is dan dertig dagen voor de toepassing van de prijsvermindering." In English: when announcing a price reduction, the seller states the lowest price applied in a period of at least thirty days before the reduction. Source: wetten.overheid.nl, Besluit prijsaanduiding producten article 5a. So if your win-back email says "was 45, now 35", that 45 has to be the lowest price you actually charged in the past thirty days. If you ran a 40 promotion two weeks ago, your reference price is 40.
One thing here is less black and white than it looks, and almost nobody mentions it. The decree is named for products, and the explanatory memorandum to the implementing act says that in the Prijzenwet, products means movable property under the Civil Code. A haircut is not movable property. Yet in its own guidance for businesses the Dutch consumer authority ACM applies the rule to services without qualification, writing "Is uw product (of dienst) korter dan 30 dagen op de markt?", treating product and service alike. Sources: Kamerstuk 35940 no. 3, and acm.nl on stating prices. Practically: the regulator is the one who will hold you to it, so follow it even though the statute itself reads narrower than you would expect.
Two smaller points that come up in a win-back campaign. Prices shown to consumers always include VAT and any additional costs; the decree defines the selling price as the final price for a unit of a product including turnover tax and all other taxes. And if you send a lapsed client a gift voucher instead of a discount, a minimum validity applies: ACM ConsuWijzer states "Een cadeaubon die u na 1 januari 2022 kocht, moet minimaal 2 jaar geldig zijn", a gift voucher bought after 1 January 2022 must be valid for at least two years. With only an issue date on it, five years; with no date at all, it never expires. A credit note is different: "Er bestaan geen regels voor hoelang een tegoedbon geldig moet zijn." Source: ACM ConsuWijzer on gift vouchers and credit notes.
Whether you may offer a deal only to lapsed clients and not to your regulars: we found no ruling or guidance from ACM or the chamber of commerce on that. It happens everywhere and there is no sign that it is a problem, but we are not writing here that it is allowed while no source says so.
What to do with the feedback
A good day-90 email often produces more feedback than many other client surveys. What you do with that feedback determines whether the effort pays off.
Common reasons and concrete actions:
"Too expensive now." Reply: "Thank you for letting me know. Our rates have indeed risen this year. If you ever want to come back for a specific treatment that fits your budget, let me know and we will look together." Do not open a discount spiral, do leave the door open.
"Tried another stylist." Reply: "Understood, sometimes you have to try something else to know what you have. If you ever want to come back, you are welcome." No pressure, sometimes people return after 6 months.
"Schedule no longer fits." Reply: "Tell me what would fit, then we can see if we can find something." Sometimes a different time slot does fit, sometimes a colleague is available at a time you do not work yourself.
"Moved or too far." Reply: "Understand. If you are nearby for family or work, you can always come by again. Otherwise I wish you a good salon in your new area." Close sympathetically, do not raise false hope.
"Did not enjoy it, service was different than before." Reply: "Sorry to hear that. May I ask what was different? I would like to understand so we can do something about it." Probe further, accept criticism without defense.
"Personal circumstances changed." Reply: "No problem, hopefully it works out for you again when the time is right. No pressure." Respect for the situation.
Seeing the pattern in this feedback is more valuable than an individual booking. Three clients in a row saying "too expensive" tells you something about your pricing strategy. Five clients saying "schedule does not fit" tells you something about your opening hours.
Channel: SMS, email, or phone?
First the rule, because a win-back campaign is by definition unsolicited commercial mail. Dutch telecoms law requires prior consent for commercial messages in article 11.7(1), but 11.7(3) carves out an exception for contact details you obtained when selling your own service. You may then approach that client about "eigen gelijksoortige producten of diensten", your own similar products or services, provided you clearly offered a free opt-out when you collected the address, and provided you offer that opt-out again in every message.
For a salon that means three things. A client who once sat in your chair can be emailed about a haircut. Someone who only asked for a quote, or whose address came off a list, cannot. And every message needs an unsubscribe link, including a personal-looking note from you to a lapsed regular. Source: Telecommunicatiewet article 11.7, consulted on 10 September 2026.
A different channel per phase because the message is different.
SMS / messaging for day 30. Short message, low threshold, high open rate. Fits a reminder.
Email for day 60 and day 90. Longer message with context, personal sender, no pushy character. Fits a reason and an honest question.
Phone only for exceptional clients. High-value clients you really miss (high spend, long history, personal bond). No phone call to someone who came twice, that feels intrusive.
What does NOT work:
- Letter in the mailbox (too slow, too impersonal)
- Direct mail flyer (anonymous, feels like spam)
- Push notification via an app (most clients do not have the app)
- Posts on social media (the client does not see it, and if they do it feels anonymous)
Keep the line personal and direct. A win-back campaign works on a one-to-one level, not on mass-marketing.
Which numbers do you measure on your win-back campaign?
Three key numbers cover it:
Response rate per phase. What percentage responds (books or replies) on day 30, day 60, and day 90. Tells you which phase works for your clients.
Return rate per segment. What percentage of warm, lukewarm, and cold lapsers eventually books back, within 60 days after last contact. Do not go looking for a benchmark to measure against; none exists for the Dutch salon industry, and everything you find comes from a software vendor presenting its own platform data. Compare your second round against your first. That is the only comparison that is about your business.
Value per reactivated client over 6 months. The first booking is not the whole story, look at what they spend across half a year. A recovered client who only comes once brings in less than one who returns to their old cycle.
Compare costs (time and any SMS fees) against revenue, and set that against what a new client from advertising costs you.
How to apply this in your salon next week
Start by segmenting. Filter your client base by last-visit date and split them into the four segments. Send day-30 messages this week to everyone who has not come in the last 30 to 45 days when they normally would have.
In CelerBook you sort your client list by last visit, which puts the people who have been away longest at the top, and per client you see the preferred staff member, previous treatments, and your own notes. That is your segmentation in one action. What is not in there, and it is exactly the step in this playbook that stays manual: a message that fires by itself once a client has been away for a number of weeks. The automatic emails and texts CelerBook sends are about appointments that are already booked, not about clients who stop showing up. So you send the messages in this playbook yourself, and the sorted list is your work queue. Pay-as-you-go from 0.25 EUR ex VAT per completed appointment, no fixed monthly fees. Try CelerBook for free.
