Free loyalty program and back office for salons

A client who forgets to rebook is a chair you cannot fill.

Color and cut clients return every 6 to 8 weeks. The real question is whether they book with you or try someone new.

Short answer

Is there a free loyalty app for a salon?

Yes. KANJIN (kanjin.app) gives a salon a digital stamp card on the customer's phone number, with no app for them to download, no limit on customers and no time limit. The free plan also sends up to 20 Google review requests a month and one email a month to as many as 150 customers, everyone asked the same way. The paid plan is $39 a month per shop and is never needed to run the card.

The rebooking gap

When a client forgets to rebook

A client leaves pleased, life gets busy, and nobody books the next appointment.

At week 10 the roots show, and they book wherever has a free chair that Saturday.

Many salons only spot this when a familiar name stops appearing in the diary.

A list sorted by last visit shows that gap weeks earlier.

70

days, then Slipping away

Salon cycles are long, so KANJIN waits 70 days. A note at day 30 would chase someone who is not even due for color.

An example

One color client over a year

A client pays $90 for a cut and color every 7 weeks.

That is about 7 visits, or $630, in a year.

The reward after 6 stamps is a blow-dry, about 30 minutes of chair time.

If the client drifts to another salon after visit 3, about $360 of that year goes with them.

Thirty minutes is small next to $360. The card exists to keep the next booking in your diary.

Stamp card

Fewer stamps, a bigger reward

6 stamps earn a free treatment or blow-dry.

Six visits on an 8-week cycle take about a year. Ten would take almost two.

A treatment or blow-dry costs chair time more than product, and clients value it.

Stamp at the desk after payment, from the number already on their booking.

Free calculator

How many 5-star reviews to reach 4.8 stars?

New clients read ratings before they trust a stranger with their hair. Enter your rating and how many reviews you have, and the calculator says how many 5-star reviews in a row it takes to reach the rating you want.

To show 4.5 stars

55 reviews

55 five-star reviews in a row takes you to 175 reviews and an average of 4.45, which Google displays as 4.5.

To reach a true 4.5 average, rather than a rating that displays as 4.5, you need 72 reviews.

How long that takes

2 reviews / week

28 weeks

5 reviews / week

11 weeks

10 reviews / week

6 weeks

Asking after the visit is what changes the pace. Most customers mean to leave a review, walk out, and forget.

We assume every new review is 5 stars and none are removed. A higher target gets much harder: each extra tenth of a star needs more reviews than the last, because we divide by how far the target sits below 5.0.

Salon owners often ask

  • “My booking software already sends reminders.”

    Good, keep it. Reminders help clients who booked. KANJIN helps with the clients who never booked the next visit at all.

  • “Stylists rent chairs here. Whose client is it?”

    The list sits in the salon’s account. Staff logins let the owner choose what each stylist can open.

  • “Clients do not want more email.”

    Only clients who said yes are emailed at all. Each person gets at most 2 marketing emails a week, and you decide when.

Hair salon questions

How do I get salon clients to rebook?
Ask at the desk before they leave, every visit. For those who still slip, the Stamp card screen lists them under Slipping away after 70 days.
Should I pay stylists commission or chair rent?
It depends on your rent and how full each chair is. Paying your team is in the free back office. It compares hourly pay, commission and chair rent with your numbers.
Can my salon ask clients for Google reviews?
Yes, if you ask everyone and offer nothing for it. KANJIN emails a review request 1 hour after the stamp, to clients who left an email and agreed. The free plan covers 20 a month.
If I leave KANJIN, do I keep my client list?
Yes. Settings has one press to export the list as a spreadsheet. There is no contract.
