A professional hairstylist has shared her list of common client behaviors that make her job more challenging. These include showing up late with a takeaway coffee, not holding one’s head still during blow-drying, lifting one’s head up at the sink during hair washing, being a former hairdresser, and booking appointments for major services but only wanting a quick trim. The stylist also advises against complaining about previous hairstylists, using purple shampoo excessively, and waiting until the last minute to book appointments during busy seasons.
