Witness the debates, among others, of the wearing of religious symbols in the public arena. Hair is an aspect of appearance loaded with meanings that shift according to context. A billion pound industry trades on the desire to avoid a bad hair day. In the barbershops of hipster London, beards are combed and coaxed into just the right shape.&#13;<br /> &#13;<br /> In early modern Europe, dress was regulated by ‘sumptuary laws’. These regulations set out who could wear what and when, according to a hierarchy of privileges believed to be accorded by God. Some of the laws related not just to clothing but also to hair. In 1637, for example, the authorities of the city of Basel prohibited its male inhabitants from wearing “hair and long tresses that are unseemly and unnecessarily ample and long, that hang down over the eyes, as well as artificial hair and hairpieces<em>.”</em>&#13;<br /> &#13;<br /> Basel was a centre for print, scholarship and radical thought. It and other cities had recently undergone the sweeping religious changes known as the Reformation. In some areas, the Reformation made extravagant excesses a subject of discussion and attempted to regulate clothing in regard to new aesthetics of piety and morals of modesty. In Basel, sumptuary law restricted the usage of gold and silver borders, edgings and braids, and prohibited the wearing of hats decorated with beads, pearls and jewelry.&#13;<br /> &#13;<br /> Dr Stefan Hanß is a historian of material culture and the body in early modern Europe. “When I began to examine the archives of cities such as Augsburg and Nuremburg, I realised that hair is everywhere, mentioned again and again. We’re talking about a period when outward appearance was everything – and a community’s religious purity was defined by its inhabitants’ social and bodily behavior,” he says.  &#13;<br /> &#13;<br /> “Hair is the stuff of emotions and high on the list of things people really mind about. It’s a product of our bodies and part of our identity. That’s why enforced shaving is so demeaning and a punishment commonly meted out to criminals. When authorities impose rules and regulations about hair as a means of discipline, there is often a strong reaction.”&#13;<br /> &#13;<br /> Early modern European cities enacted laws that defined the privileges and duties of different groups. Noblemen, clerics and peasants, for example, were expected to dress and behave in certain ways: what was appropriate for one group was inappropriate for another. In the wake of the Reformation, people were expected to comply with new rules on dress – but, as always, there were some who were determined to test the limits of authority.&#13;<br /> &#13;<br /> Among them was a French noblewoman called Charlotte Duplessis-Mornay whose husband, caught up in religious conflict, moved with his family to Montauban, a small city in southern France’s Midi-Pyrénées. ֱ̽Protestant clergy of Montauban had made hair a prime issue of religious and social discipline, and had preached against women wearing braids and curly tresses in public. Charlotte, however, refused to <em>changer de coiffure</em> and in 1584 attended church adorned in luxuriant curls.&#13;<br /> &#13;<br /> Charlotte’s defiance provoked what she described in her memoirs as a huge <em>scandale</em>. ֱ̽Protestant consistory, the city’s disciplinary authority, started official investigations that resulted in the excommunication from the church of her entire family. News of Charlotte’s stance on the question of her hair travelled wider than Montauban. ֱ̽magistrates of Toulouse were also informed.&#13;<br /> &#13;<br /> Wearing a black scarf that covered her curls, Charlotte appeared in front of the consistory to defend her position. She openly contradicted the consistory’s religious interpretation of hairstyles and pointed out inconsistencies in the Bible on matters of women’s appearance. On one hand, she pointed to the Apostle Paul’s well-known demand that women cover their hair during prayers and, on the other, she quoted biblical passages that declared braids and jewelry to be heavenly adornments of spouses.&#13;<br /> &#13;<br /> Charlotte boldly demanded clarification of her case: “Since it were very pernicious that the opinions of men, although good and holy, should be put in the place of the commandment of God, I desire that this matter may be cleared up for the well-being and the concord of the churches.” She concluded: “Voilà, messieurs, quel est mon but et mon opinion en ce faict.” [<em>Voilà</em>, gentlemen, that’s my goal and my opinion in this matter.”] Sadly, the outcome of her dispute is not known.&#13;<br /> &#13;<br /> Hanß is one of the first historians to pursue in detail the question of how hairstyles mattered in 16th- and 17th-century Germany, the heartland of the Reformation’s upheavals. “Hair is highly significant as it represented much more than civic order,” he says. “In such a hair-literate society, people were innovative and managed their appearances by going to barbershops, using medicinal remedies, and staging distinctive beards and hairstyles.”&#13;<br /> &#13;</p> <blockquote class="clearfix cam-float-right"><p>&#13;<br /> Charlotte’s defiance provoked what she described as a huge scandale. ֱ̽Protestant consistory started official investigations that resulted in the excommunication of her entire family.&#13; </p></blockquote> <p>&#13;<br /> &#13;<br /> In cities, barber guilds flourished and members of these craft guilds opened shops like the one shown in a German print from 1568. Barbers washed, cut and perfumed the customer’s head and facial hair with the many perfumed waters, pomades and medical ointments that were available in their shops. With scissors, razors, tweezers and combs, a man’s hair was delicately groomed to face the day in a perfectly appropriate manner.&#13;<br /> &#13;<br /> “People spent large amounts of money and time on their hair to produce the desired look,” says Hanß. “Within the parameters established by societal norms and by local regulations, people embraced the latest styles and created novel fashions. Dressing to look the part for special occasions, they were always pushing at the boundaries.”&#13;<br /> &#13;<br /> Recipe books contain countless instructions to the proper treatment of hair and hint at an “experimental world in early modern Germany”, in which men and women creatively engaged with expectations by meeting or subverting them. Hanß suggests: “Going to the barber meant visiting a place where razors were used, diseases were cured, and rumours were shared, to manage one’s own physical appearance when going to church services, weddings or market places.”&#13;<br /> &#13;<br /> Historians are puzzling over the question of why, after a period that favoured the clean-shaven, beards made a come-back in the 16th century. An extreme example is the cultivation of long beards among South German urban and Habsburg court élites late in the century. ֱ̽imperial military councillor, Andreas Rauber, famously grew a beard of two strands that reached down to the floor. It was widely rumoured that Rauber could lift an anvil with his beard.&#13;<br /> &#13;<br /> Hanß suggests that beards had become potent signifiers of nobility and masculinity. “Anatomical and medical treatises defined the growth of facial hair as a byproduct of a man’s sperm. Beards became such a prominent feature of manhood that almost everyone, in stark contrast to the 15th century, decided to have a beard – and some took this to extremes,” he says.&#13;<br /> &#13;<br /> “For men, women and children, hair played an important role in the making of group cultures. Hair can indicate political and religious belonging – and in the case of early modern courts, noblemen signaled their loyalty to their rulers by imitations of princely hairstyles. What we do with our hair conveys a multitude of messages about ourselves – and this was certainly the case in early modern Europe.”&#13;<br /> &#13;<br /> Dr Stefan Hanß has recently submitted a journal article on the confessional, gendered and emotional implications of forced shavings endured by people enslaved in the Habsburg and Ottoman lands.

Now, a ֱ̽ of Cambridge physicist and collaborators have quantified the curliness of human hair and developed a mathematical theory that explains the shape of a ponytail.</p>&#13; &#13; <p>Research <a href="https://journals.aps.org:443/prl/abstract/10.1103/PhysRevLett.108.078101" target="_blank">published today</a> (13 February) in <em>Physical Review Letters</em> provides the first quantitative understanding of the distribution of hairs in a ponytail. To derive the Ponytail Shape Equation, the scientists took account of the stiffness of the hairs, the effects of gravity and the presence of the random curliness or waviness that is ubiquitous in human hair. Together with a new quantity described in the article – the Rapunzel Number –  the equation can, they say, be used to predict the shape of any ponytail.</p>&#13; &#13; <p> ֱ̽research by Professor Raymond Goldstein from the ֱ̽ of Cambridge, Professor Robin Ball from the ֱ̽ of Warwick, and colleagues, provides new understanding of how a bundle is swelled by the outward pressure which arises from collisions between the component hairs. This has important implications for understanding the structure of many materials made up of random fibres, such as wool and fur. ֱ̽research will also have resonance with the computer graphics and animation industry, where the representation of hair has been a challenging problem.</p>&#13; &#13; <p>“It’s a remarkably simple equation,” explained Goldstein, who is the Schlumberger Professor of Complex Physical Systems at Cambridge's Department of Applied Mathematics and Theoretical Physics. “Our findings extend some central paradigms in statistical physics and show how they can be used to solve a problem that has puzzled scientists and artists ever since Leonardo da Vinci remarked on the fluid-like streamlines of hair in his notebooks 500 years ago.</p>&#13; &#13; <p><img alt="A ponytail composed of approximately 10,000 human hairs, each 25 cm long, from a commercial hair switch.

Physicists aim to find simplicity out of complexity, and this is a case in point.”</p>&#13; &#13; <p>“We imagine that at least half of the population has direct experience with the properties of ponytails, and we all have likely wondered about the fluffiness of hair,” added Goldstein, whose research was partially funded by the Schlumberger Chair Fund. “We now have the first quantitative description of this phenomenon and how it competes with gravity.”</p>&#13; &#13; <p>Professor Goldstein will be presenting the research at the March Meeting of the American Physical Society in Boston on 28 February 2012.</p>&#13; </div></div></div><div class="field field-name-field-content-summary field-type-text-with-summary field-label-hidden"><div class="field-items"><div class="field-item even"><p><p>New research provides the first mathematical understanding of the shape of a ponytail and could have implications for the textile industry, computer animation and personal care products.</p>&#13; </p></div></div></div><div class="field field-name-field-content-quote field-type-text-long field-label-hidden"><div class="field-items"><div class="field-item even">Our findings solve a problem that has puzzled scientists and artists ever since Leonardo da Vinci remarked on the fluid-like streamlines of hair in his notebooks 500 years ago.</div></div></div><div class="field field-name-field-content-quote-name field-type-text field-label-hidden"><div class="field-items"><div class="field-item even">Professor Ray Goldstein</div></div></div><div class="field field-name-field-image-credit field-type-link-field field-label-hidden"><div class="field-items"><div class="field-item even"><a href="/" target="_blank">Nick Saffell</a></div></div></div><div class="field field-name-field-image-desctiprion field-type-text field-label-hidden"><div class="field-items"><div class="field-item even">Suvi&#039;s ponytail</div></div></div><div class="field field-name-field-cc-attribute-text field-type-text-long field-label-hidden"><div class="field-items"><div class="field-item even"><p><a href="http://creativecommons.org/licenses/by-nc-sa/3.0/"><img alt="" src="/sites/www.cam.ac.uk/files/80x15.png" style="width: 80px; height: 15px;" /></a></p>&#13; &#13; <p>This work is licensed under a <a href="http://creativecommons.org/licenses/by-nc-sa/3.0/">Creative Commons Licence</a>.
