Why are there fewer and fewer barbershops now?

It's too difficult to recruit people, but the salary is not high and the working hours are long. Low wages are mainly reflected in assistants and employees who wash their hair. Because working in barber shops depends on commission, some shops may have guaranteed wages, but some shops don't, so bosses with guaranteed wages will be under great pressure, so working in barber shops looks glamorous, but in fact the wages are not high. The pressure of rent, water and electricity makes it difficult to recruit people and makes people who run barbershops miserable.
