Henna is a reddish dye prepared from the dried and powdered leaves of the henna tree.{{cite book|isbn= 978-0025054707|last1= Bailey|first1= L.H.|last2= Bailey|first2= E.Z.|year= 1976|title= Hortus Third: A concise dictionary of plants cultivated in the United States and Canada|publisher= Macmillan|location= New York|url-access= registration|url= https://archive.org/details/hortusthirdconci00bail}}{{Cite web |date=2025-04-12 |title=Henna tree {{!}} Description, Uses, & Facts {{!}} Britannica |url=https://www.britannica.com/plant/henna |access-date=2025-05-14 |website=www.britannica.com |language=en}} It has been used since at least the ancient Egyptian period as a hair and body dye, notably in the temporary body art of mehndi (or "henna tattoo") resulting from the staining of the skin using dyes from the henna plant. After henna stains reach their peak colour, they hold for a few days and then gradually wear off by way of exfoliation, typically within one to three weeks.

Henna has been used in ancient Egypt, ancient Near East and the Indian subcontinent to dye skin, hair, and fingernails; as well as fabrics including silk, wool, and leather. Historically, henna was used in West Asia including the Arabian Peninsula and in Carthage, other parts of North Africa, West Africa, Central Africa, the Horn of Africa and the Indian subcontinent.

The name henna is used in other skin and hair dyes, such as black henna and neutral henna, neither of which is derived from the henna plant.{{cite web|url=http://www.hennaforhair.com/faq/cassiaobovata.html|access-date=5 May 2013|website=Henna for Hair|title=Cassia Obovata|year=2004|first=Catherine|last= Cartwright-Jones}}{{cite news| title = FDA: Beware of "black henna" tattoos| access-date = 5 May 2013| url = https://www.washingtonpost.com/blogs/style-blog/wp/2013/03/26/fda-beware-of-black-henna-tattoos/|newspaper=The Washington Post|first=Brady |last=Dennis|date=26 March 2013}}

History

The origins of the initial human uses of henna are uncertain; however, there are records that the plant was marketed in Babylonia,{{cite book|url= https://books.google.com/books?id=qulwDwAAQBAJ&pg=PA65|page=65|title=The Devils and Evil Spirits of Babylonia|author=R.

Preparation and application

File:Henna for hair.jpg

=Body art=

Whole, unbroken henna leaves will not stain the skin because the active chemical agent, lawsone, is bound within the plant. However, dried henna leaves will stain the skin if they are mashed into a paste. The lawsone will gradually migrate from the henna paste into the outer layer of the skin and bind to the proteins in it, creating a stain.

Since it is difficult to form intricate patterns from coarsely crushed leaves, henna is commonly traded as a powder{{cite web|title=Henna Powder of Prem Dulhan|url=http://www.premhenna.com/natural-henna-powder.html|publisher=Lia|access-date=23 December 2015|archive-date=23 December 2015|archive-url=https://web.archive.org/web/20151223190636/http://www.premhenna.com/natural-henna-powder.html|url-status=dead}} made by drying, milling and sifting the leaves. The dry powder is mixed with one of a number of liquids, including water, lemon juice, strong tea, and other ingredients, depending on the tradition. Many artists use sugar or molasses in the paste to improve consistency to keep it stuck to the skin better. The henna mix must rest between one and 48 hours before use in order to release the lawsone from the leaf matter. The timing depends on the crop of henna being used. Essential oils with high levels of monoterpene alcohols, such as tea tree, cajuput, or lavender, will improve skin stain characteristics. Other essential oils, such as eucalyptus and clove, are not used because they can irritate the skin.

The paste can be applied with many traditional and innovative tools, starting with a basic stick or twig. In Morocco, a syringe is common. A plastic cone similar to those used to pipe icing onto cakes is used in India. A light stain may be achieved within minutes, but the longer the paste is left on the skin, the darker and longer lasting the stain will be, so it needs to be left on as long as possible. To prevent it from drying or falling off the skin, the paste is often sealed down by dabbing a sugar/lemon mix over the dried paste or adding some form of sugar to the paste. After some time, the dry paste is simply brushed or scraped away. The paste should be kept on the skin for a minimum of four to six hours, but longer times and even wearing the paste overnight is a common practice. Removal should not be done with water, as water interferes with the oxidation process of stain development. Cooking oil may be used to loosen dry paste.

Henna stains are orange when the paste is first removed but darken over the following three days to a deep reddish brown due to oxidation. Soles and palms have the thickest layer of skin and so take up the most lawsone, and take it to the greatest depth, so that hands and feet will have the darkest and most long-lasting stains. Some also believe that steaming or warming the henna pattern will darken the stain, either during the time the paste is still on the skin or after the paste has been removed. It is debatable whether this adds to the color of the result as well. After the stain reaches its peak color, it holds for a few days, then gradually wears off by way of exfoliation, typically within one to three weeks.

Natural henna pastes containing only henna powder, a liquid (water, lemon juice, etc.) and an essential oil (lavender, cajuput, tea tree etc.) are not "shelf stable," meaning they expire quickly, and cannot be left out on a shelf for over one week without losing their ability to stain the skin.

The leaf of the henna plant contains a finite amount of lawsone. As a result, once the powder has been mixed into a paste, this leaching of dye molecules into the mixture will only occur for an average of two to six days. If a paste will not be used within the first few days after mixing, it can be frozen for up to four months to halt the dye release, for thawing and use at a later time. Commercially packaged pastes that remain able to stain the skin for longer than seven days without refrigeration or freezing contain other chemicals besides henna that may be dangerous to the skin. After the initial seven-day release of lawsone dye, the henna leaf is spent, therefore, any dye created by these commercial cones on the skin after this time period is actually the result of other compounds in the product. These chemicals are often undisclosed on packaging and have a wide range of colors, including what appears to be a natural-looking color stain produced by dyes such as sodium picramate. These products often do not contain any henna. There are many adulterated henna pastes such as these, and others, for sale today that are erroneously marketed as "natural", "pure", or "organic", all containing potentially dangerous undisclosed additives. The length of time a pre-manufactured paste takes to arrive in the hands of consumers is typically longer than the seven-day dye release window of henna, therefore one can reasonably expect that any pre-made mass-produced cone that is not shipped frozen is a potentially harmful adulterated chemical variety.{{Unbalanced opinion|date=July 2021}} ·

Henna only stains the skin one color, a variation of reddish brown, at full maturity three days after application.

Powdered fresh henna, unlike pre-mixed paste, can be easily shipped around the world and stored for many years in a well-sealed package.

Body art quality henna is often more finely sifted than henna powders for hair.

==History==

File:Henna hair colour squares.jpeg

In Ancient Egypt, Ahmose-Henuttamehu (17th Dynasty, 1574 BCE) was probably a daughter of Seqenenre Tao and Ahmose Inhapy. Smith reports that the mummy of Henuttamehu's own hair had been dyed a bright red at the sides, probably with henna.G. Elliott Smith, The Royal Mummies, Duckworth Publishing; (September 2000)

In Europe, henna was popular among women connected to the aesthetic movement and the Pre-Raphaelite artists of England in the 1800s. Dante Gabriel Rossetti's wife and muse, Elizabeth Siddal, had naturally bright red hair. Contrary to the cultural tradition in Britain that considered red hair unattractive, the Pre-Raphaelites fetishized red hair. Siddal was portrayed by Rossetti in many paintings that emphasized her flowing red hair.{{cite web|title=Aesthetics|url=http://www.fashion-era.com/aesthetics.htm|access-date=15 August 2011}} The other Pre-Raphaelites, including Evelyn De Morgan and Frederick Sandys, academic classicists such as Frederic Leighton, and French painters such as Gaston Bussière and the Impressionists, further popularized the association of henna-dyed hair and young bohemian women.

Opera singer Adelina Patti is sometimes credited with popularizing the use of henna in Europe in the late nineteenth century. Parisian courtesan Cora Pearl was often referred to as La Lune Rousse (the red-haired moon) for dyeing her hair red. In her memoirs, she relates an incident when she dyed her pet dog's fur to match her own hair.{{cite book|author=Cora Pearl|title=Mémoires de Cora Pearl|url=https://books.google.com/books?id=l0ttAAAAMAAJ|year=1886|publisher=J.

It gained popularity among young people in the 1960s through a growing interest in Eastern cultures.{{cite book|last=Sherrow|first=Victoria|title=Encyclopedia of Hair: A Cultural History|year=2006|publisher=Greenwood|isbn=978-0313331459|pages=[https://archive.org/details/encyclopediaofha0000sher/page/206 206–207]|url=https://archive.org/details/encyclopediaofha0000sher/page/206}}

==Today==

Commercially packaged henna, intended for use as a cosmetic hair dye, originated in ancient Egypt and the ancient Near East and is now popular in many countries in South Asia, Europe, Australia, and North America. The color that results from dyeing with henna depends on the original color of the hair, as well as the quality of the henna, and can range from orange to auburn to burgundy. Henna can be mixed with other natural hair dyes, including Cassia obovata for lighter shades of red or even blond and indigo to achieve brown and black shades. Some products sold as "henna" include these other natural dyes. Others may include metal salts that can interact with other chemical treatments, oils and waxes that may inhibit the dye, or dyes which may be allergens.

Apart from its use as a hair dye, henna has recently been used as a temporal substitute to eyebrow pencil or even as eyebrow embroidery.{{cite web|url=https://www.instyle.com/news/henna-eyebrow-tinting|title=You Can Now Tint Your Eyebrows With Henna|website=InStyle.com|language=en|access-date=17 December 2018|archive-date=17 December 2018|archive-url=https://web.archive.org/web/20181217110649/https://www.instyle.com/news/henna-eyebrow-tinting|url-status=dead}}

Traditions of henna as body art

The different words for henna in ancient languages imply that it had more than one point of discovery and origin, as well as different pathways of daily and ceremonial use.{{fact|date=February 2024}}{{or-inline|date=February 2024}}

Henna has been used to adorn young women's bodies as part of social and holiday celebrations since the late Bronze Age in the Eastern Mediterranean.{{fact|date=February 2024}} The earliest text mentioning henna in the context of marriage and fertility celebrations comes from the Ugaritic legend of Baal and Anath,{{Cite book|author=Johannes C. de Moor |title=The seasonal pattern in the Ugaritic myth of Balu, according to the version of Ilimilku (Alter Orient und Altes Testament) |publisher=Butzon & Bercker |location=Kevelaer |year=1971 |isbn=978-3-7887-0293-9 |oclc=201316}}{{Page needed|date=August 2010}} which has references to women marking themselves with henna in preparation to meet their husbands, and Anath adorning herself with henna to celebrate a victory over the enemies of Baal.

Wall paintings excavated at Akrotiri (dating before the eruption of Thera in 1680 BCE) show women with markings consistent with henna on their nails, palms and soles, in a tableau consistent with the henna bridal description from Ugarit.{{Cite book|author=Christos D̲oumas |title=The wall-paintings of Thera |publisher=Thera Foundation |location=Athens |year=1992 |isbn=978-960-220-274-6 |oclc=30069766}}{{Page needed|date=August 2010}} Many statuettes of young women dating between 1500 and 500 BCE along the Mediterranean coastline have raised hands with markings consistent with henna. This early connection between young, fertile women and henna seems to be the origin of the Night of the Henna, which is now celebrated in all the Middle East.

The Night of the Henna was celebrated by most groups in the areas where henna grew naturally: Jews,{{Cite book|author=Erich Brauer |author2=Raphael Patai |title=The Jews of Kurdistan |publisher=Wayne State University Press |location=Detroit |year=1993 |isbn=978-0-8143-2392-2 |oclc=27266639}}{{Page needed|date=August 2010}} Muslims,{{Cite book|author=Edward Westermarck |title=Marriage ceremonies in Morocco |publisher=Curzon Press |location=London |year=1972 |orig-year=1914 |isbn=978-0-87471-089-2 |oclc=633323}}{{Page needed|date=August 2010}} Sikhs, and Hindus among others, all celebrated marriages and weddings by adorning the bride, and often the groom, with henna.

Across the henna-growing region, Purim, Eid,{{Cite book|title=The victim and its masks: an essay on sacrifice and masquerade in the Maghreb|last=Abdellah Hammoudi|publisher=University of Chicago Press|year=1993|isbn=978-0-226-31525-6|location=Chicago|oclc=27265476|author-link=Abdellah Hammoudi}}{{Page needed|date=August 2010}} Diwali,{{Cite book|author=Jogendra Saksena |year=1979 |title=Art of Rajasthan: Henna and Floor Decorations |location=Delhi |publisher=Sundeep |oclc=7219114 }}{{Page needed|date=August 2010}} Karva Chauth, Passover, Mawlid, and most saints' days were celebrated with some henna. Favourite horses, donkeys, and salukis had their hooves, paws, and tails hennaed. Battle victories, births, circumcision, birthdays, Zār, as well as weddings, usually included some henna as part of the celebration. Bridal henna nights remain an important custom in many of these areas, particularly among traditional families.

Henna was regarded as having Barakah ("blessings"),{{where|date=August 2014}}{{when|date=August 2014}} and was applied for luck as well as joy and beauty.Westermarck, E. (1926). Ritual and Belief in Morocco Vols 1 & 2. London, UK: Macmillan and Company, Limited{{Page needed|date=August 2010}} Brides typically had the most henna and the most complex patterns to support their greatest joy and wishes for luck. Some bridal traditions were very complex, such as those in Yemen, where the Jewish bridal henna process took four or five days to complete, with multiple applications and resist work. Specific henna designs may also vary by region. For example, geometric shapes such as triangles and diamonds characteristic of traditional Moroccan beading are represented in Moroccan henna designs.

The fashion of "Bridal Mehndi" in North Indian, Bangladesh, Northern Libya and Pakistan is currently growing in complexity and elaboration, with new innovations in glitter, gilding, and fine-line work. Recent technological innovations in grinding, sifting, temperature control, and packaging henna, as well as government encouragement for henna cultivation, have improved the dye content and artistic potential for henna.

Though traditional henna artists were from the Nai caste in India and barbering castes in other countries (lower social classes), talented contemporary henna artists can command high fees for their work.{{citation needed|date=August 2014}} Women in countries where women are discouraged from working outside the home can find socially acceptable, lucrative work doing henna.{{cite news|url=https://www.youtube.com/watch?v=M3SHY9_OwvQ| archive-url=https://ghostarchive.org/varchive/youtube/20211113/M3SHY9_OwvQ| archive-date=13 November 2021 | url-status=live|title=Easy Mehndi Design Tutorial |date=4 December 2014}}{{cbignore}} Morocco, Mauritania,{{Cite book|author=Aline Tauzin |year=1998 |title=Le henné, art des femmes de Mauritanie |trans-title=Henna, the art of Mauritanian women |language=fr |location=Paris |publisher=UNESCO |isbn=978-92-3-203487-8 }}{{Page needed|date=August 2010}} Yemen, Libya, Somalia, Kenya, Sudan, the United Arab Emirates, India and many other countries have thriving women's henna businesses. These businesses are often open all night for Eid, Diwali and Karva Chauth. Many women may work together during a large wedding, wherein hundreds of guests have henna applied to their body parts. This particular event at a marriage is known as the Mehndi Celebration or Mehndi Night or Laylat al Henna,{{where|date=August 2014}}{{by whom|date=August 2014}} and is mainly held for the bride and groom.

In Morocco, henna is applied symbolically when individuals go through life cycle events.{{cite thesis |last1=Spurles |first1=Kelly |last2=L |first2=Patricia |title=Henna for Brides and Gazelles: Ritual, Women's Work and Tourism in Morocco |date=2004 |id={{ProQuest|305053576}} |hdl=1866/14244 |isbn=978-0-612-97895-9 }} Moroccans refer to the paste as henna and the designs as naqsh, which means painting or inscription. In Morocco, there are two types of henna artists: non-specialists, who traditionally partake in wedding rituals, and specialists, who partake in tourism and decorative henna. Nqaasha, the low-end Henna specialists, are known for attracting tourists, which they refer to as gazelles or international tourists, in artisan slang.

For Moroccans, a wedding festival can last up to 5 days, with 2 days involving henna art. One of these days is referred to as azmomeg (meaning unknown), and is the Thursday before the wedding where guests are invited to apply henna to the bride. The other henna ceremony occurs after the wedding ceremony, called the Day of Henna. On this day, typically an older woman applies henna to the bride after she dips in the mikveh to ward off evil spirits who may be jealous of the newlyweds. The groom is also painted with henna after the wedding. During the groom's henna painting, he commonly wears black clothing; this tradition emerged from the Pact of Umar as the Jews were not permitted to dress similar to colorful Muslim dress in Morocco.

==Pakistan==

In Pakistan, henna is often used in weddings, Eid ul fitr, Eidul Adha, milad and other events.{{cite web|date=4 August 2014|title=A brief history of henna|url=https://tribune.com.pk/story/741476/a-brief-history-of-henna/|access-date=19 December 2018|website=The Express Tribune|language=en-US}} The henna ceremony is known as the Rasm-e-Heena, which is often one of the most important pre-wedding ceremonies celebrated by both the bride and groom's families. The night of mehndi, the gathering at which the application of the henna is performed, usually falls on the second day of the festivities and one day before the wedding itself. The process commonly involves only the bride and groom but can also include close friends or other family members. The hands of the wedding couple are elegantly painted on this night to act as a sign of their union.

In Sindh, henna is known as "Mehndi" and serves both as a decorative art on the hands, arms, feet, and legs, and as a natural dye for gray hair, used by both women and men in every ceremonial occasions, events and festivals.

==Saudi Arabia==

In Saudi Arabia, henna has long been associated with wedding traditions in certain regions. Women adorn their hands and feet with intricate henna designs during these occasions. The night before the wedding is referred to as the "Henna Night" or “Al-Ghumra.” On this evening” female relatives of the bride and groom gather at the bride's family home to decorate the bride's hands and feet with henna patterns.{{Cite web |title=Henna Body Paint Encourages Children to Observe Ramadan Fasting in Northern Saudi Arabia.

During Eid Al-Fitr and Eid Al-Adha, women also come together to prepare special henna mixtures for designs that vary by age group.

On December 3, 2024, the tradition of "Henna, rituals, aesthetic and social practices" was inscribed on UNESCO’s Intangible Cultural Heritage List. This recognition was a collaborative effort between 16 Arab countries, including Saudi Arabia, Sudan, Egypt, the UAE, Iraq, Jordan, Kuwait, Palestine, Tunisia, Algeria, Bahrain, Morocco, Mauritania, Oman, Yemen, and Qatar. The nomination was led by the United Arab Emirates, with Saudi Arabia represented by the Heritage Commission, in cooperation with the Saudi National Commission for Education, Culture, and Science, and Saudi Arabia's permanent delegation to UNESCO.{{Cite web |title=UNESCO - Henna: Rituals, Aesthetic and Social Practices. |url=https://ich.unesco.org/en/RL/henna-rituals-aesthetic-and-social-practices-02116}}

==Somalia==

In Somalia, henna has been used for centuries. It is cultivated from the leaves of the Ellan tree, which grows wild in the mountainous regions of Somalia. It is used for practical purposes such as dyeing hair and also more extravagantly by coloring the fingers and toes of married women and creating intricate designs.{{cite book |last1=Akou |first1=Heather Marie |title=The Politics of Dress in Somali Culture |date=2011 |publisher=Indiana University Press |isbn=978-0-253-22313-5 |page=108 |url=https://books.google.com/books?id=0Eg-b6EQt-cC&pg=PA108 }} It is also applied to the hands and feet of young Somali women in preparation for their weddings and all the Islamic celebrations. Sometimes also done by young school girls for several occasions

==Spain==

Henna was cultivated in the Nasrid kingdom of Granada and applied to the face and hair by both sexes.

After the Castilian conquest of Granada (1492), it was forbidden for Moriscos as it was a sign distinguishing them from Old Christians.

After the expulsion of the Moriscos (1609–1614), cultivation ceased.{{cite book|surname=Caro Baroja |first=Julio |author-link=Julio Caro Baroja |title=Los moriscos del Reino de Granada.

In Sudan, Henna dyes are regarded with a special sanctity in Sudan and for that reason they are always present during happy occasions: weddings and children circumcisions, in particular.

Henna has been part of Sudan's social and cultural heritage ever since the days of Sudan's ancient civilizations, where both would-be couples would get their hands and feet pigmented with this natural dye.

Children also have their hands and feet dyed with henna during their circumcision festivity.

==Tunisia==

In Tunisia, the traditional wedding process begins 8 days before the wedding ceremony when a basket is delivered to the bride, which contains henna.{{cite book |last1=Schely-Newman |first1=Esther |title=Our Lives are But Stories: Narratives of Tunisian-Israeli Women |date=2002 |publisher=Wayne State University Press |isbn=978-0-8143-2876-7 |page=55 |url=https://books.google.com/books?id=uMgho4rZap0C&pg=PA55 }} The mother of the groom supervises the process in order to ensure all is being done correctly.{{cite book |last1=Schely-Newman |first1=Esther |title=Our Lives are But Stories: Narratives of Tunisian-Israeli Women |date=2002 |publisher=Wayne State University Press |isbn=978-0-8143-2876-7 |page=53 |url=https://books.google.com/books?id=uMgho4rZap0C&pg=PA53 }} Today, the groom accompanies the bride in the ritual at the henna party, but the majority of henna painting is done on the bride's body.

During the Victorian era, Turkey was a major exporter of henna for use in dyeing hair.Sherrow, Victoria. Encyclopedia of Hair: A Cultural History. Westport, CT: Greenwood Press, 2006. 156.

==Yemen==

For Yemenite Jews, most of them living in Israel, the purpose of a henna party is to ward off evil from the couple before their wedding.{{cite journal |last1=Buse |first1=William |title=What becomes a bride the most: the Yemenite Jewish henna |journal=Visual Ethnography |date=31 December 2015 |volume=4 |issue=2 |doi=10.12835/ve2015.2-0049 }} In some areas, the party has evolved from tradition to an opportunity for the family to show off their wealth in the dressing of the bride. For other communities, it is practiced as a ritual that has been passed on for generations. The dressing of the bride is typically done by a post-menopausal woman in the bride's family. Often, the dresser of the bride sings to the bride as she is dressed in exquisite designs. These songs discuss marriage, what married life is like, and address the feelings a bride may have before her wedding. The costumes worn by Yemenite brides to their henna parties is considered some of the most exquisite attire in the Yemenite community. These outfits include robes, headwear, and often several pounds of silver jewelry. This jewelry often holds fresh green herbs to ward off the Jinn in keeping with the ritual element of the party.

The zavfa is the procession of the bride from her mother's house to the Henna Party. During the zavfa, the guests of the party sing traditional songs to the bride and bang on tin plates and drums to ward off evil. Today, it is common for the groom to join in on this aspect of the ritual, although traditionally it was only for the bride. During the party, guests eat, sing, and dance. Initially, the singing and dancing were to ward off the Jinn with loud noises, but today these elements are associated with the mitzvah of entertaining the bride and groom on their wedding day.

In the middle of the party, the bride returns to her home to be painted in henna mixed by her mother. The mixture consists of rose water, eggs, cognac, salt, and shadab, believed to be a magical herb that repels evil. The bride changes into a less elaborate outfit and incense is burned while she is painted with henna. Then, another zavfa (procession) occurs as the bride returns to her party.

Back at the henna party, the bride sits on stage while family members and friends come up to her to have their palms marked with blots of henna. These marks represent the long-lasting marriage as henna remains for many days. It also represents the blood from breaking the hymen upon consummating the marriage on the wedding night. Others add that the red stain on the hands of the guests is to mislead the evil spirits of the Jinn who are looking for the bride. After the painting, the party ends after lasting about 4 or 5 hours.

Health effects

Henna is known to be dangerous to people with glucose-6-phosphate dehydrogenase deficiency (G6PD deficiency), which is more common in males than females. Infants and children of particular ethnic groups, mainly from the Middle East and North Africa, are especially vulnerable.{{cite journal |last1=de Groot |first1=Anton C. |title=Side-effects of henna and semi-permanent 'black henna' tattoos: a full review |journal=Contact Dermatitis |date=July 2013 |volume=69 |issue=1 |pages=1–25 |doi=10.1111/cod.12074 |pmid=23782354 |s2cid=140100016 |doi-access=free }}

Though user accounts cite few other negative effects of natural henna paste, save for occasional mild allergic reactions (often associated with lemon juice or essential oils in a paste and not the henna itself), pre-mixed commercial henna body art pastes may have undisclosed ingredients added to darken stain or to alter the stain color. The health risks involved in pre-mixed paste can be significant. The United States Food and Drug Administration (FDA) does consider these risks to be adulterants and therefore illegal for use on skin. Some commercial pastes have been noted to include: p-Phenylenediamine, sodium picramate, amaranth (red dye #2 banned in the US in 1976), silver nitrate, carmine, pyrogallol, disperse orange dye, and chromium.{{cite journal |last1=Kang |first1=Ik-Joon |last2=Lee |first2=Mu-Hyoung |title=Quantification of para-phenylenediamine and heavy metals in henna dye |journal=Contact Dermatitis |date=July 2006 |volume=55 |issue=1 |pages=26–29 |doi=10.1111/j.0105-1873.2006.00845.x |pmid=16842550 |s2cid=22176978 }} These have been found to cause allergic reactions, chronic inflammatory reactions, or late-onset allergic reactions to hairdressing products and textile dyes.{{cite journal |last1=Dron |first1=P |last2=Lafourcade |first2=MP |last3=Leprince |first3=F |last4=Nonotte-Varly |first4=C |last5=Van Der Brempt |first5=X |last6=Banoun |first6=L |last7=Sullerot |first7=I |last8=This-Vaissette |first8=C |last9=Parisot |first9=L |last10=Moneret-Vautrin |first10=DA |title=Allergies associated with body piercing and tattoos: a report of the Allergy Vigilance Network |journal=European Annals of Allergy and Clinical Immunology |date=June 2007 |volume=39 |issue=6 |pages=189–192 |pmid=17713170 |s2cid=7903601 }}{{cite journal |last1=Raupp |first1=P |last2=Hassan |first2=JA |last3=Varughese |first3=M |last4=Kristiansson |first4=B |title=Henna causes life threatening haemolysis in glucose-6-phosphate dehydrogenase deficiency |journal=Archives of Disease in Childhood |date=1 November 2001 |volume=85 |issue=5 |pages=411–412 |doi=10.1136/adc.85.5.411 |pmid=11668106 |pmc=1718961 }}

Black henna

Natural henna produces a rich red-brown stain, which can darken in the days after it is first applied and last for several weeks. It is sometimes referred to as "red henna" to differentiate it from products sold as "black henna" or "neutral henna," which may not actually contain henna, but are instead made from other plants or dyes.{{Cite web |date=26 April 2018 |title=Dangers of black henna |url=https://www.nhs.uk/live-well/healthy-body/black-henna-neutral-henna-ppd-dangers/ |url-status=dead |archive-url=https://web.archive.org/web/20200808235748/https://www.nhs.uk/live-well/healthy-body/black-henna-neutral-henna-ppd-dangers/ |archive-date=8 August 2020 |access-date=8 August 2020 |website=nhs.uk |language=en }}

Partly fermented, dried indigo was called black henna because it could be used in combination with henna to dye hair black. This gave rise to the belief that there was such a thing as black henna which could dye skin black. Indigo will not dye skin black. Pictures of indigenous people with black body art (either alkalized henna or from some other source) also fed the belief that there was such a thing as black henna.{{citation needed|date=July 2020}}

A neutral henna does not change the colour of hair. This is not henna powder; it is usually the powder of the plant Senna italica (often referred to by the synonym Cassia obovata) or closely related Cassia and Senna species.{{citation needed|date=July 2020}}

In the 1990s, henna artists in Africa, India, Bali, the Arabian Peninsula and the West began to experiment with PPD-based black hair dye, applying it as a thick paste as they would apply henna, in an effort to find something that would quickly make jet-black temporary body art.
