One of our biggest complaints about hairdressing salons is that they attempt to make the experience 'generic' by giving you the next available stylist. The problem starts when you find a stylist you like - but you don't know their name, or if you do, you don't know their availability over the coming months!
The worst part - what if they leave their job? You'll have no idea (since you don't know their schedule), and you won't know their new salon either.
This is the problem Appointment Scheduler tries to fix. Your barber or stylist signs up to have a schedule - and passes the link to it around to their most loyal clients. As the barber or stylist changes jobs, their clients will follow too - giving them bargaining power with their employers.
