All the Sassoons, Fekkais, and Hershbergers of this world started cutting hair in relatively small, unknown salons. They gained a cult-like following because of their talent and because of their strong work ethic. As a salon owner, your prime source of revenue comes from services you offer your clients. It all depends on how many you see per day, week, and month.
We know you rock your scissors like a modern day Edward scissorhands but it's sadly usually the logistics and scheduling tools that slow salon owners down. You want to optimize your time and not necessarily maximize it so you can take advantage of every second of your work day without penalizing your clients or your practice.
