An esthetician's guide to WhatsApp automation: treatment by treatment

Generic appointment automation treats every booking the same: a time, a person, a reminder. An esthetician's work is not shaped like that. A course of peels has an interval between sessions that matters clinically, a lash set has a fill window that decides whether the client keeps or loses the set, and a facial before an event needs to happen at a specific remove from it.

Building around the treatment rather than around a generic appointment is the difference between automation that helps and automation that sends everybody the same reminder.

Every treatment has its own shape

Duration varies by an order of magnitude across a price list.

Preparation differs: what to avoid beforehand, what to arrive without, what needs testing.

The rebooking interval is clinical for some treatments and cosmetic for others.

Aftercare differs and matters most where the client's behaviour affects the result.

Some are a course, not an appointment, and booking one session at a time loses the course.

Encode the treatment, not the slot, which is the design decision this whole article rests on.

Pre-treatment, which is where problems start

Retinoid and acid use before certain treatments is the classic issue, and clients forget.

Sun exposure before several services, which is seasonal and frequently overlooked.

Recent treatments elsewhere, which clients do not think to mention.

Waxing and hair removal timing before some facial treatments.

Send the preparation notes when it matters, which is days before rather than in the booking confirmation nobody rereads.

Ask them to confirm they have followed it, which surfaces the problem before they travel.

Intervals and courses

A course of treatments has spacing that affects the result, and clients book the next one whenever suits them.

Book the whole course where the protocol is a course, rather than one at a time.

Prompt at the right point, calculated from the treatment date and its protocol rather than a fixed period.

Flag a session too soon, which is a clinical consideration rather than a scheduling one.

Track where somebody is in a course, since a client mid-course who lapses loses the benefit of the ones they paid for.

Say what the interval is and why, since clients who understand it keep to it.

Building it with CodeWords

CodeWords connects to more than 3,000 integrations, and the connection is made once and reused.

1. Open CodeWords and start a new automation.
2. Describe what should happen in plain language to Cody, the automation builder: the treatment, its preparation, its interval and its aftercare.
3. Authorize the connections to your booking system and your WhatsApp Business Platform account.
4. Describe the exceptions: a session booked too soon, missing preparation, a course not completed, a reported reaction.
5. Set up one treatment end to end before adding the rest.

You describe the outcome; Cody builds it, connects it, and deploys it. The free plan covers light use, with Pro at $39 per month and Business at $100 per month as usage grows; details are on the pricing page.

Aftercare that actually gets read

Send it after, not only in person, because nobody remembers instructions given while getting dressed.

Short and specific to the treatment they actually had.

The first twenty-four hours separately from the longer-term advice, since that is when it matters most.

Say what is normal and what is not, with a clear route to reach you for the second.

A message is kept in a way a leaflet is not, which is the practical advantage of this channel.

Do not assess a reported problem in the thread — route it to you, promptly.

The fill window

Lash and nail work has a window where a fill maintains the set and after which it becomes a new full set.

Clients do not track it, and discover they have missed it when they try to book.

That is a lost sale and an unhappy client, which is a worse outcome than either alone.

Prompt inside the window, calculated per client from their last appointment.

Say what happens if they miss it, plainly, since the price difference is the motivator.

Offer the slot rather than asking them to call, which is where the rebooking is won or lost.

Events and deadlines

Clients book around weddings and events, which are fixed dates working backwards.

Some treatments need to be a specific distance from an event, not as close as possible.

Ask about the date when the enquiry mentions one, since it changes the recommendation.

Plan the sequence backwards where a course is involved, which is a conversation rather than a booking.

Build in the buffer for anything that could react, which is the reason the interval exists.

Flag the booking that is too close, before it is taken rather than after.

What stays with you

Whether a treatment is suitable, which is your assessment.

Anything about a reaction, routed to you immediately.

The consultation, which is a conversation rather than a form.

Advice about a concern, which is not something a message should provide.

The recommendation, since clients book what you suggest and that is the relationship.

Anything involving a minor, which carries additional considerations depending on the treatment and your jurisdiction.

Retail and recommendations

Estheticians recommend products constantly and sell a fraction of what they recommend, largely because the recommendation happens at the moment the client is least able to act on it.

Send what you recommended after the appointment, which is when they are thinking about it and not half-dressed.

Say why it was for them, specifically, since a generic product message is marketing and a specific one is advice they asked for.

Time the repurchase prompt to when the product would actually run out, which depends on the size and how you told them to use it.

Do not push what they did not discuss, which converts a recommendation into a sales message and costs the trust that made it work.

Track what they bought, since the follow-up recommendation depends on it.

Keep it occasional. The retail message works because it is rare and relevant, and a monthly one is neither.

Making it survive

Encode the protocol per treatment rather than one generic flow.

Check the interval before confirming a booking within a course.

Keep consultation and reaction records out of the thread and in the client record.

Handle the client who replies about a problem with a route to you and not an automated answer.

Report the outcome: treatments booked, courses completed, fills booked inside the window, and preparation confirmations.

Limits worth knowing about

Protocols come from your training and products, not from a general article.

Insurance terms may specify consultation and testing requirements.

Scope of practice varies by jurisdiction, particularly for anything at the medical end.

Clients do not follow preparation reliably, which is why confirming matters.

Automation does not make a treatment work, it removes the reasons it does not — missed preparation, wrong interval, forgotten aftercare.

What to build first

One treatment, end to end: its preparation notes at the right moment, its booking, its aftercare afterwards, and its rebooking prompt at the correct interval. Pick the one you do most. It is a day's work, it proves the shape, and it is how you find out which parts of your protocol were living only in your head.

Two habits make the difference. Calculate the rebooking prompt from the treatment and its protocol rather than a fixed period, since a lash fill window and a peel interval are different things and one generic reminder serves neither. And send preparation notes days ahead rather than in the booking confirmation, because the confirmation is not reread and the preparation is what determines whether the appointment can go ahead.

Frequently asked questions

Why not use generic appointment automation?

Because an esthetician's work is shaped by the treatment rather than the slot. Durations, preparation, intervals and aftercare all differ, and a single reminder flow serves none of them properly.

When should preparation notes be sent?

Days before, not in the booking confirmation, which nobody rereads. Ask the client to confirm they have followed it, so a problem surfaces before they travel to the appointment.

How should courses be handled?

Book the whole course where the protocol is a course, prompt from the treatment date rather than a fixed period, and flag a session booked too soon — which is a clinical consideration rather than a scheduling one.

What makes aftercare effective?

Sending it afterwards as well as giving it in person, keeping it short and specific to the treatment, separating the first twenty-four hours from longer-term advice, and saying what is normal with a clear route to reach you for what is not.

What is the fill window and why does it matter?

The period where a lash or nail fill maintains the set, after which it becomes a full set. Clients do not track it and find out when they try to book — which is a lost sale and an unhappy client at the same time.

How should event bookings be handled?

By asking about the date, since some treatments need to be a specific distance from an event rather than as close as possible, and flagging a booking that is too close before it is taken.

What should never be automated?

Suitability assessment, anything about a reaction, the consultation itself, advice about a concern, and the recommendation — which is the relationship rather than a workflow step.

Where do the protocols come from?

Your training, your products and your insurer, not a general article. The automation encodes what you already do; it does not decide what the protocol should be.

How should product recommendations be followed up?

By sending what you actually recommended after the appointment, with the reason it was for them, and prompting repurchase when the product would genuinely run out rather than on a fixed schedule.

Why not send regular product offers?

Because the recommendation works on trust and relevance. A monthly product message is marketing rather than advice, and it costs the credibility that made the in-person recommendation convert.
