The rebooking rate is the whole business
Per stylist, visible, and improved at the chair rather than by email afterwards.
This is the entire product. A client who rebooks at the chair has a maintenance interval. A client who does not has an intention, and intentions decay at exactly the rate that turns six weeks into ten.
Nobody in most salons can tell you the rebooking rate per stylist, and it is the single highest-leverage number in the business. Producing it is usually the first thing worth building, because you cannot improve what nobody has ever seen.
