What's the difference between Henna tattoos and Temporary tattoos?

Hennas are painted on; Temporary tattoos use a transfer process.

Temporary tattoos usually consist of five main elements: the front of the sheet of paper, the back of the sheet of paper, ink, glue and a protective plastic sheet. The front of the sheet is covered with a special coating upon which the tattoo image is printed with special inks. A layer of glue is then applied on top of the image. A thin, transparent plastic sheet is placed over the front of the sheet to protect the image and glue layer. The back of the sheet is left untreated and has a list of ingredients and instructions printed on it.

Transfer temporary tattoos are usually applied by removing the plastic sheet, placing the image face down against the skin and moistening the backing by wetting it thoroughly. The backing can then be carefully removed, leaving the image in place. Among the largest suppliers of temporary tattoos include California Tattoo, Artpro Printing

Henna tattoos use a paste made from powdered leaves of the Henna plant. Its active dye binds with the keratin in skin, fingernails, and hair. Traditional henna is drawn in delicate patterns on the hands and feet, but modern henna is applied in all sorts of designs anywhere on the body. Unlike other forms of temporary tattoos, henna does not allow for a full range of colors but only shades of reds, browns, and near-blacks. The paste is applied and left on the skin for several hours to stain. The stain will gradually fade away as the skin sheds. Henna tattoos can last days to over a month depending on application and aftercare.

Other types of temporary tattoos include temporary airbrush tattoos and ballpoint pen tattoos.

Tattoo Skin Art

Tattoos are popular in many parts of the world, owing much to custom and traditional use. Similar to piercing, tribal and religious tattoos can be found on many devout members of a faith, including crosses, ankhs, stars of David, and other religious iconography. Typically tattooing—sometimes referred to as “skin art” by those who are interested in it—is done at a tattoo parlor, by experienced artists. Usually a tattoo artist will have to apprentice under another, more skilled artist before they can work on their own. Women in particular have embraced the current popularity of tattoos, with many choosing to get tattoos across their lower back.
