A patch test 48 hours before colour keeps skin safe and appointments on schedule - and it's the easiest thing in the world to forget to mention at booking time.
When it sends
When an upcoming appointment includes a colour service and it's the customer's first colour with you (or it's been a long while since their last one). Like the prep note, it's about their own booking, so it reaches them regardless of marketing preferences.
Good to know
- It only exists if your menu actually includes colour work - no colour services, no reminder, nothing to configure.
- The message invites them to pop in beforehand and to reply if they can't - so the conversation lands with you, not in silence on the day.
