Do appointment reminders reduce no-shows for a salon or clinic?

Yes. A Cochrane review of randomised trials found mobile text reminders improved attendance at healthcare appointments compared with no reminder, with a risk ratio of 1.14.

That review is not a promise for a salon in Greater Kailash or a dental clinic in Green Park. It is a published healthcare figure. I will not turn it into your empty-chair count.

What the review actually published

The Cochrane page, citing Gurol-Urganci and colleagues, reports moderate quality evidence from seven studies and 5841 participants. The risk ratio versus no reminder is 1.14, with a 95 percent confidence interval from 1.03 to 1.26.

The same page reports attendance of 67.8 percent with no reminder and 78.6 percent with mobile messaging reminders, across the studies they pooled. Phone call reminders sat at 80.3 percent in that pooled line. Text sat close to a phone call, with a risk ratio of 0.99 against calls.

Those trials were healthcare appointments, not Saturday colour. The authors say the evidence is low to moderate, and that more trials are needed. I will not hide that.

I will not invent a Delhi salon percentage on top of their table. Salon WhatsApp bookings already refused a no-show figure I cannot see. This page adds the public review. It does not replace your week.

What a reminder is, in a Delhi shop

A reminder is a message that names the hour you already wrote down. It is not a second diary.

Booking automation can send that message after the slot exists. Chat can send it on WhatsApp if that is where the person already wrote. A voice booking still needs the same write first. What the voice agent writes into is that destination.

Reply within an hour is the first answer. A reminder is the later nudge, the day before, or the morning of. Do not buy a reminder to hide a thread that sat until Monday.

A deposit is a stronger hold than a nudge. A UPI deposit before you confirm is that hold. I will not tell you a text is the same as money.

The inbox floor is Rs 15,000, listed on pricing. That floor is the inbox job, not a reminder product I priced on its own.

How to read the number without lying to yourself

Take last week’s empty chairs, or empty 11am slots. That count is your baseline.

The Cochrane risk ratio is 1.14 versus no reminder, in the trials they pooled. I will not multiply your chairs by 1.14 and call the answer yours. Your road, your reviews, and whether people can find the door still sit outside that review.

If last week had almost no empty slots, a reminder will not invent demand. If last week was a string of names who never arrived, a reminder is a cheap thing to try after the diary is one list.

I will not invent the rupee cost of an SMS or a WhatsApp template on this page. Those are provider rates. Open the rate you will actually pay. A Greater Kailash chair that already texts regulars by hand may only need that habit written down, not a new product.

What a reminder will not fix

Two people who both said 2pm. The reminder then reminds both. That is a worse Saturday.

A stale hour on the card. The reminder repeats the lie.

A person who booked to “keep the slot” and never meant to come. A text will not grow a conscience.

A clinic that wants the reminder to carry a diagnosis. That stays off the card.

I will not tell you reminders are free of downside. A message at 6am is a nuisance. A message that names a treatment the person did not want named in a family chat is a privacy problem. Ask before you put clinical words in a text.

Count the empty chairs first

Open last Saturday, or last clinic week. Mark every name that did not sit down. If the list is empty, stop. If the list is the afternoon, write the slot once, then add a reminder that names only the hour.

Then get in touch. Bring that list. I will say a reminder is worth wiring, a deposit is the next hold, or the hole is still two people writing in two books.
