The first ever Black henna tattoo It is a plant that is native to the tropical regions of Africa, South Asia to Australia, and leaves produce a pigment called lawsone, a red-orange color, which is well thus binding proteins, and is used to dye skin, hair, nails and silk. Pure henna should not irritate the skin, although some people can develop allergies, henna may actually be a good conditioner for the skin. Traditional henna tattoos are a caramel-colored or reddish brown, but not black.
To do this, Black henna tattoo true leaves are dried and ground into a powder that is mixed with lemon juice, or other liquids slightly strong acids to form a tea paste. It is left to “rest” for 6-12 hours for the cellulose in the leaves can dissolve and release the lawsone. Once on the skin of lawsone molecules migrate from the henna paste into the surface layers of the skin. Cracks and paste falls but dabbing sugar or lemon mixture over the dry paste can seal in. When you remove the dough the stain will be orange but darkens to a reddish brown. It can be reduced by addition of steam, heating or with alkaline solutions but chlorinated water and soap can spoil the stain. The stain should disappear as your skin exfoliates and sheds the outer layer of colored skin cells.
The concept of Black henna tattoo may come from tribal people seen with black tattoos that can be alkaline with henna or other sources. Indigo plant may be partially fermented and dried and then mixed with henna and used to dye black hair, but can not dye the skin.

This chemical is used in hair dyes, but only 6% or less, can not come into direct contact with the scalp and should be rinsed immediately. Otherwise the henna “black” tattoos that typically represents 10% -60% and is left on the skin for half an hour.
PPD is used because it is a cheap substitute for henna and staining the skin in half an hour, while the henna can last up to 8 hours before coloring is complete. PPD can be mixed with peroxide or peroxide can be scanned on the tattoo to bring out the color and dries quickly. However, the PPD is much more abrasive henna and a number of adverse effects:
Severe allergic reactions can cause permanent sensitivity so the use of PPD in hair dye base is life threatening.
