SMS for hairdressers and salons: fewer gaps in the diary
A cancelled appointment you learn about in time is a slot you still sell. A no-show is a loss.
The reminder, but with a way out
Twenty-four hours ahead, with the option to cancel in one reply. That is the point: above all you want to know who is not coming.
The waiting list
A slot opens up: send a message to those on the list, first to reply gets it. That is the only way to still convert a same-day cancellation.
The return reminder
Six to eight weeks after the last appointment, depending on the treatment. This brings work in rather than only avoiding loss.
What you do not do
Weekly promotions. Your clients gave their number for an appointment.
In practice
Put the salon name at the front and keep the message short enough for one SMS. Across hundreds of appointments a month, that difference adds up.
