The History of the Barber Pole: Bloodletting, Basins and Stripes

The barber pole is one of the oldest trade signs still in everyday use. Like the three gold balls of a pawnbroker or the coloured show globes that once hung in apothecary windows, it announced a trade to people who might not be able to read ^[1]. Yet the pole's stripes do not describe haircuts. They point back to a time when the person who trimmed your beard might also pull your teeth, set your bones and open a vein.

This story explains what the barber pole meant, how its symbolism developed and why it survives. It is closely connected to our Journal story on barber-surgeons and the long road to modern trichology.

When barbers were surgeons

In medieval Europe, barbers did far more than cut hair. They performed minor surgery, extracted teeth and carried out bloodletting, the practice of deliberately removing blood to treat illness ^[1][2]. Bloodletting was based on the ancient theory of the four humours, which held that health depended on a balance of bodily fluids. Removing blood was thought to restore that balance, and it remained a mainstream treatment for many centuries before modern medicine discredited it for most conditions ^[4].

Part of the reason barbers took on this work lies in church history. During the twelfth century a series of church councils, including the Council of Tours in 1163, restricted clergy from practising surgery ^[1]. Monks and priests had been among the most educated healers, and with them withdrawn, the hands-on work of cutting and bleeding passed increasingly to barbers, who already owned sharp instruments and were skilled with them. Over time a distinction grew between university-trained physicians, academic surgeons and the barber-surgeons who served ordinary people. In Paris, the College of Saint-Côme and Saint-Damien, established around 1210, distinguished surgeons of the long robe from barber-surgeons of the short robe ^[1].

What a medieval barber-surgeon actually did

It helps to imagine a working day. A barber-surgeon in a medieval or early modern town might shave several customers in the morning, trim hair and beards, and then turn to medical work: lancing a boil, dressing a wound, pulling a rotten tooth or bleeding a patient on the advice of a physician ^[2]. Military campaigns relied heavily on barber-surgeons, who treated wounds on and near the battlefield. Their training was practical, gained through apprenticeship rather than university study, and their status was lower than that of physicians, who diagnosed and prescribed but rarely cut.

That division of labour shaped the sign outside the shop. Physicians did not need a pole. Barber-surgeons did, because their trade was hands-on and their customers came to them directly. The pole was an advertisement for skilled manual services, and bleeding happened to be one of the most common.

The decline of bloodletting

Bloodletting faded slowly. Through the eighteenth and nineteenth centuries physicians continued to recommend it for a wide range of conditions, and leeches were imported in huge numbers in some European countries ^[4]. Only as clinical evidence accumulated in the nineteenth century did doctors begin to abandon it for most illnesses. Today it survives in modern medicine only for a small number of specific conditions, carried out by medical professionals under very different principles ^[4]. By then the barbers had long since left surgery behind, but they kept the sign.

What the pole represents

The traditional explanation of the barber pole draws directly on bloodletting. The patient gripped a staff to make the veins in the arm stand out and to encourage blood flow. The original pole represented that staff. A brass basin at the top represented the vessel in which leeches were kept, and a basin at the bottom represented the bowl that received the blood ^[1]. The red and white helix is commonly explained as blood and bandages, with clean or bloodied bandages wound around the pole and hung outside to dry, though that particular detail is better treated as tradition than documented fact.

Scholars have also noted that the twisted motif resembles the caduceus, the staff of the Greek god Hermes, which became associated with commerce and, later and somewhat confusingly, with medicine ^[1]. Symbols like these accumulate meanings over time, and the pole probably drew on several at once.

Colours with rules

In some places the colours were regulated. After barbers and surgeons in England were united into a single company, a statute required barbers to use a red and white pole and surgeons to use a red pole ^[1]. In France surgeons used a red pole with a basin attached to mark their premises ^[1]. In Renaissance Amsterdam, one account says the stripes advertised a menu of services: red for bleeding, white for setting bones or pulling teeth, and blue for a shave if nothing more urgent was needed ^[1].

The Company of Barber-Surgeons

In London the relationship between barbers and surgeons was formalised in 1540, when an Act of Parliament under Henry VIII united the Company of Barbers with the Guild of Surgeons to form the Company of Barber-Surgeons ^[3]. The union lasted for just over two centuries. In 1745 the surgeons separated to form their own company, which eventually became the Royal College of Surgeons of England, while the barbers continued as the Worshipful Company of Barbers, which still exists in the City of London today ^[3].

The separation of 1745 marks a turning point. Surgery was becoming a scientific, hospital-based profession, while barbering was becoming a grooming trade. The barber pole, however, stayed on the barbers' side of the split. It had become the sign of their shops, and customers recognised it.

Red, white and blue

In the United States and several other countries, including Canada, Japan, South Korea, the Philippines and Vietnam, barber poles usually carry red, white and blue stripes ^[1]. The blue is often explained as a nod to national flag colours. Another popular interpretation says red stands for arterial blood, blue for venous blood and white for bandages ^[1]. It is a neat story, but it appears to be a later rationalisation rather than an original meaning. In the United Kingdom and much of Europe, red and white remains standard.

Spinning poles and the last manufacturers

The modern rotating barber pole, lit from inside and turned by an electric motor, became a familiar sight in the twentieth century. Before 1950 there were four manufacturers of barber poles in the United States. In 1950 William Marvy of St. Paul, Minnesota, began making poles, and his company went on to become the best-known American manufacturer ^[1][5]. The company has also long been associated with barbershop supplies such as sanitising products, an interesting echo of the trade's medical past.

Why the pole survives

The barber pole survives because it works. It is visible from a distance, instantly recognisable and unambiguous. A new shop that wants to signal a traditional barbering experience can install one and be understood immediately. The pole has also become a metaphor in its own right: a lighthouse painted with a spiral stripe is said to have barber-pole colours ^[1].

From barber-surgeons to trichologists

The barber pole is a reminder that hair care and medicine were once tightly bound together. Over the centuries those threads separated into distinct professions: surgeons and physicians on one side, barbers and hairdressers on the other. In the twentieth century a new specialty emerged in between, trichology, the study of hair and scalp, which focuses on the health of hair rather than its style. Our Journal story From Barber-Surgeons to Trichologists follows that path in detail, and readers who want to know more about the modern field can visit https://trichology.com.

Reading a barber pole today

Next time you pass a barber pole, you are looking at a compact history lesson. The staff the patient gripped, the basins for leeches and blood, the stripes of bandages, and the colour rules of English statutes and French surgeons are all folded into a cheerful spinning sign. Few customers think about bloodletting when they walk in for a fade, and that is probably for the best. But the pole remembers.
