Henna (Lawsonia inermis, also known as hina, the henna tree, the mignonette tree, and the Egyptian privet)[1][2] is a flowering plant and the sole species of the Lawsonia genus. The English name "henna" comes from the Arabic حِنَّاء (ALA-LC: ḥinnāʾ; pronounced [ħɪnˈnæːʔ]) or, colloquially حنا, loosely pronounced as /ħinna/.
The name henna also refers to the dye prepared from the plant and the art of temporary tattooing based on those dyes. Henna has been used since antiquity to dye skin, hair, and fingernails, as well as fabrics including silk, wool, and leather. The name is mistakenly used in other skin and hair dyes, such as black henna and neutral henna, neither of which are derived from the henna plant.[3][4]

Description
Henna is a tall shrub or small tree, standing 1.8 to 7.6 m (5 ft 10 in to 24 ft 10 in) tall. It is glabrous and multi-branched, with spine-tipped branchlets. The leaves grow opposite each other on the stem and are glabrous, sub-sessile, elliptical, and lanceolate (long and wider in the middle; average dimensions are 1.5–5.0 cm x 0.5–2 cm or 0.6–2 in x 0.2–0.8 in), acuminate (tapering to a long point), and have depressed veins on the dorsal surface.[2] Henna flowers have four sepals and a 2 mm (0.079 in) calyx tube with 3 mm (0.12 in) spread lobes. Its petals are obvate, with white or red stamens found in pairs on the rim of the calyx tube. The ovary is four-celled, 5 mm (0.20 in) long, and erect. Henna fruits are small, brownish capsules, 4–8 mm (0.16–0.31 in) in diameter, with 32–49 seeds per fruit, and open irregularly into four splits.[5]
Cultivation
The henna plant is native to northern Africa, western and southern Asia, and northern Australasia in semi-arid zones and tropical.[2][6] It produces the most dye when grown in temperatures between 35 and 45 °C (95 and 113 °F).[7] During the onset of precipitation intervals, the plant grows rapidly; putting out new shoots, then growth slows. The leaves gradually yellow and fall during prolonged dry or cool intervals. It does not thrive where minimum temperatures are below 11 °C. Temperatures below 5 °C will kill the henna plant.
Uses
Small Henna plant
Henna has been used since the Bronze Age to dye skin (including body art), hair, fingernails, leather, silk and wool. In several parts of the world it is traditionally used in various festivals and celebrations. There is mention of henna as a hair dye in Indian court records around 400 CE,[8] in Rome during the Roman Empire, and in Spain during Convivencia.[9] It was listed in the medical texts of the Ebers Papyrus (16th-century BCE Egypt)[10] and by Ibn Qayyim al-Jawziyya (14th century CE, Syria and Egypt) as a medicinal herb.[11] In Morocco, wool is dyed and ornamented with henna, as are drumheads and other leather goods.
Lawsone, an active compound in Henna
Use of henna for body art has enjoyed a recent renaissance due to improvements in cultivation, processing, and the emigration of people from traditional henna-using regions.[12]
For skin dyeing, a paste of ground henna (either prepared from a dried powder or from fresh ground leaves) is placed in contact with the skin from a few hours to overnight. Henna stains can last a few days to a month depending on the quality of the paste, individual skin type, and how long the paste is allowed to stay on the skin.
Henna also acts as an anti-fungal[13] and a preservative for leather and cloth.
Henna flowers have been used to create perfume since ancient times, and henna perfume is experiencing a resurgence. Henna repels some insect pests and mildew.
Henna's coloring properties are due to lawsone, a burgundy organic compound that has an affinity for bonding with protein. Lawsone is primarily concentrated in the leaves, especially in the petioles of the leaf. Lawsone content in leaves is negatively correlated with the number of seeds in the fruits.[14]

Whole, unbroken henna leaves will not stain the skin. Henna will not stain skin until the lawsone molecules are made available (released) from the henna leaf. Fresh henna leaves will stain the skin if they are smashed with a mildly acidic liquid. 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 fast stain.
Since it is difficult to form intricate patterns from coarse crushed leaves, henna is commonly traded as a powder made by drying, milling and sifting the leaves. The dry powder is mixed with lemon juice, strong tea, or other mildly acidic liquids to make a preparation with toothpaste-like consistency, which can be used to make finely detailed body art. The henna mix must rest for 6 to 24 hours before use, to release the lawsone from the leaf matter. Essential oils with high levels of monoterpene alcohols such as tea tree, eucalyptus, cajeput, or lavender will improve skin stain characteristics.
The paste can be applied with many traditional and innovative tools, including resist, a cone, syringe, Jac bottle or fingers. A light stain may be achieved within minutes, the longer the paste is left on the skin, the stronger the stain will be, and should be left for several hours. 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 simply adding some form of sugar to the paste. It is debatable whether this adds to the color of the end result; some believe it increases the intensity of the shade. After time the dry paste is simply brushed or scraped away.
Henna stains are orange soon after application, but darken over the following three days to a reddish brown. 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. 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. Chlorinated water and soaps may spoil the darkening process: alkaline products may hasten the darkening process. After the stain reaches its peak color it will appear to fade, as the stained dead cells exfoliate.

History
Henna has been used as a cosmetic hair dye for 6,000 years. In Ancient Egypt, henna was known to have been used. It was commonly used for many centuries in areas of India, the Middle East, and Africa.
In Ancient Egypt, Ahmose-Henuttamehu (17th Dynasty, 1574 BCE): Henuttamehu 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.[15]
In Europe, henna was popular among women connected to the aesthetic movement and the Pre-Raphaelite artists of England in the 1800s. The fashion for Orientalism led young women with a bohemian inclination to begin tinting their hair with henna.[16] 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.[17] 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 1800s. Parisian courtesan Cora Pearl was often referred to as La Lune Rousse (the red moon) for dying her hair red. In her memoirs, she relates an incident when she dyed her pet dog's fur to match her own hair.[18] By the 1950s, Lucille Ball popularized "henna rinse" as her character, Lucy Ricardo, called it on the television show I Love Lucy. It gained popularity among young people in the 1960s through growing interest in Eastern cultures.[19]
Muslim men may use henna as a dye for hair and most particularly their beards. This is considered a sunnah, a commendable tradition of the Prophet Muhammad. Furthermore, a hadith (narration of the Prophet) holds that he encouraged Muslim women to dye their nails with henna to demonstrate femininity and distinguish their hands from the hands of men; thus some Muslim women in the Middle East apply henna to their finger and toenails as well as their hands.
