Barber Shops can differ from one to the next. One may offer shampoo services while another may not. Some provide additional services, such as shaving, beard and mustache grooming, hairpiece fittings, facials, hair coloring, highlights, and other related services such as curling hair.

Offering trimming services is just the start — facial hair services should also include oil treatments, shaping, and conditioning to keep beard and mustache hair clean and vibrant. Many barbershops even offer hot-towel massages to open up the pores and provide a premium luxury treatment.

Running a barbershop can be a profitable venture, no doubt. It's all about the hustle. You've got to offer top-notch services, manage costs effectively, and market your business well. The revenue comes not just from haircuts and shaves, but also from selling grooming products.
