What Stylon does
The day one diary stops being enough
One person needs a list. Two people need to know who, where and with what — and that is a different problem wearing the same clothes.
While you work alone, a diary is a list of times. Everything in it is yours, every slot means the same thing, and you can hold the whole week in your head without trying.
Then somebody else starts on Tuesdays, and almost overnight the same list starts producing problems it never had: two people promised the same room, a client booked with the wrong person, a Tuesday that looks empty because you were reading your own column.
A slot is now three questions
Whether an appointment can happen stopped being about the clock. It is now: is this person free, is the room free, and is the thing it needs free. All three have to be true, and a diary that only answers the first will cheerfully sell you a treatment into an occupied room.

People do not do the same things
The new person does not offer everything you offer, is slower at some of it while they learn, works three days, and has a client who will not see anybody else. If the booking page does not know that, the manager becomes the booking page — checking every request by hand, which works until the week they are away.
Everybody should see their own day, and only their own
A stylist needs today, their own clients, and nothing else. An owner needs the whole floor. Giving everybody the owner’s view is how pay rates and other people’s customers end up being discussed in the staff room; giving the owner only their own column is how the floor stops being managed. Both views have to exist, out of the same diary.

The quiet benefit: the business survives a day off
The real test of all this is the week the owner is not there. If the floor runs, the knowledge was in the system. If it does not, the knowledge was in one person, and the business has been quietly depending on them never being ill.
What changes
A booking page that can be trusted to say yes without being checked, a floor that fills evenly instead of around one person, and a day off that is actually a day off.
