Clients booking a tint or lash lift without a recent patch test get a 5-minute test slot at least 48 hours earlier. A WhatsApp message explains why and confirms both times, and the treatment stays tagged until the test is done.

The challenge
Tints and lash lifts need a patch test at least 48 hours ahead, but online bookings don't ask for one. First-time clients arrive for their appointment and have to be sent home, and the slot is lost. Staff try to call new clients in advance, and test records sit in a paper folder that nobody checks.

−80%The automation
When a brow tint, lash tint or lash lift is booked, the automation checks the client's record for a patch test in the last six months. If there isn't one, it adds a 5-minute patch test slot at least 48 hours earlier at the same studio. The client gets a WhatsApp message that explains why the test is needed and confirms both times. The main appointment carries a patch test pending tag until the test is checked in.

If none is found, a 5-minute patch test slot is added at least 48 hours earlier at the same studio.
- 04
WhatsApp confirmation
The client gets a WhatsApp message that explains why the test is needed and confirms both times.

The impact
Same-day turn-aways for a missing patch test fall by about 90%, from roughly 12 a month to 1. The front desk saves around 2 hours a week of calls, and every test is recorded with its date, so the six-month rule is applied the same way for every client.
Questions about this automation
What if there is no free test slot early enough?
If no 5-minute slot exists at least 48 hours before the treatment, the client gets a WhatsApp message offering to move the main appointment to a later date, with links to the next open times. The studio is alerted at the same time, so a technician can fit in a test before opening if needed.
Where are patch test records kept?
Each completed test is written to the client's profile in the booking system with the date, the products tested and the technician, and copied to a Google Sheets log. The six-month check reads from that record, so the studio can show when each client was last tested if asked.
What about clients already patch-tested on paper?
Existing paper records can be entered once, with the test date and products, so returning clients aren't asked again. Beyond that, the studio needs a booking system that allows slots to be added through an API, a WhatsApp Business number and the list of services that need a test. Simple automations like this are usually live within days.
