Some archaeological evidence suggest humans may have used dye on their hair as far back as the Paleolithic Period a.

Their preferred source: reddish iron oxide, which they found in the dirt and used to adorn their skin, their abodes—and their hair. Their color of choice? Black, though they did also use plant extracts to dabble in red, blue, green and gold. The bolder colors were often used for wigs they created using their own shaved hair. After analyzing hair samples from ancient Greek and Roman human remains, scientists determined some had been treated with permanent hair dye.

It is believed people initially used a combination of lead oxide and calcium hydroxide to color their strands, but when that was determined too toxic, they switched to a formula created by fermenting leeches. During the early years of the Roman Empire B. Most did this by wearing wigs died a gold hue. Much later circa A.

In , researchers at the University of Southern California published a paper in the International Journal of Cancer concluding that women who frequently dye their hair were twice as likely to develop bladder cancer as those who abstain. The European Commission on Consumer Safety took note.

A panel of scientists evaluated the paper, deemed it scientifically credible, and recommended that the E. This re-evaluation of hair-color ingredients by the E. The first is that sensitization to dye chemicals has grown considerably. The EU has categorized 27 hair-color ingredients as sensitizers, listing 10 of them as extreme and 13 strong. Although the first exposure to a sensitizer might have no noticeable effect, a subsequent exposure—to the same chemical or to similar chemicals in temporary tattoos or textiles, for example—could lead to an allergic reaction.

In the worst case, it could trigger anaphylaxis, an extreme and potentially fatal allergic response. The second issue is a lack of data on what dye chemicals do inside the human body.

When in doubt, the European Commission bans the use of a particular chemical. Our high safety standards do not only protect E.

Most recently, the SCCP deemed 2-chloro-p-phenylenediamine, used to color eyebrows and lashes, unsafe on the grounds of insufficient toxicology data. When the SCCP released the findings on sensitivity in early , Colipa the European cosmetic trade association, now known as Cosmetics Europe published a statement to "reinforce its confidence in the safety of hair dyes. Scientists working for the industry continue to point out that no undisputed epidemiological studies show a significant risk of cancer among people who color their hair.

Unless you look at a population that is exposed to hair dye every day: hairdressers. Hairdressers have a 5 percent greater chance of contracting bladder cancer than the general population. It struck me that there was no mention of the safety of hair-dye chemicals during any of the instructional classes I attended at the Energizing Summit. When I overheard a student being advised to think about her long-term health as a hairdresser, I looked up to see whether it related to contact with dyes studies have shown that wearing gloves greatly reduces the amount of dye compounds absorbed into the body.

But it turned out that the student was being counselled on her wrist position, not the use of gloves. Indeed, archaeological evidence shows that the use of dyes by humans dates back to the Palaeolithic period. Early humans used the iron oxide contained in dirt to decorate their dwellings, textiles, and bodies with the color red. Ancient Egyptians dyed their hair, but rarely did so while it was on their heads. They shaved it off, then curled and braided it to fashion wigs to protect their bald heads from the sun.

Black was the most popular color until around the 12th century BCE, when plant material was used to color the wigs red, blue, or green, and gold powder was used to create yellow. Of natural dyes, henna endures.

The ancients also used saffron, indigo, and alfalfa. But natural dyes only coat the hair temporarily, and people wanted chemically altered tresses. Analyzing hair samples has revealed that the Greeks and Romans used permanent black hair dye thousands of years ago. They mixed substances that we know today as lead oxide and calcium hydroxide to create a lead sulfide nanoparticle, which forms when the chemicals interact with sulfur linkages in keratin, a protein in hair.

When the direct application of lead proved too toxic, the Romans changed their black dye formula to one made by fermenting leeches for two months in a lead vessel. Prostitutes during the early years of the Roman Empire were required to have yellow hair to indicate their profession.

Most wore wigs, but some soaked their hair in a solution made from the ashes of burnt plants or nuts to achieve the color chemically. With the development of the scientific method in the early modern period, dyers took a more analytical approach to changing hair color, testing the efficacy and safety of new formulas. Delights for Ladies, a recipe book of household essentials published in the early s, recommends using Oyle of Vitrioll to color black hair chestnut.

The fashion for Italian blondes repeated itself—as hair-color trends do — several hundred years later in the s, when Venetian women would recline in the sun on specially built terraces with their hair drenched in corrosive solutions of lye to achieve golden locks. Blond hair was no longer limited to prostitutes.

Yet dyes were used for more than fashion or to signify occupation. Hair Tutorials. Hair Color. Share Tweet Pin Email. Hair Color History Like many great modern inventions, hair color as we now know it was invented by accident.
