While barbering can be a rewarding career, it can also be physically and mentally demanding. Long hours of standing, high levels of concentration, and dealing with difficult customers can lead to stress and burnout. Some barbers may quit due to these challenges, or because they want to pursue different career paths.

Many modern barber poles have a blue stripe, which some historical sources cite as a tribute to the colours of the America flag. In Europe, the blue stripe was meant to differentiate barbers from doctors, as the two professions gradually began to grow apart.

In this period, surgical mortality was very high due to blood loss, shock and infection. Yet, since doctors thought that bloodletting to balance 'humours' would improve health, barbers also used bloodletting razors and applied leeches. Meanwhile, physicians considered themselves to be above surgery.

The pole itself was derived from the staff that the patient gripped onto to encourage blood flow during the blood letting procedures. As for the colors, the white is said to be symbolic of the bandages used to stem the blood. Red is symbolic of the blood itself and blue of the veins.
