Black henna is composed of a chemical dye called Para-phenylenediamine — also known as PPD — which is extremely toxic and can cause severe health problems, on a short and long term basis. PPD is most often found in hair dyes and body art products. It is usually added to henna powder to produce a black stain instead of the reddish brown pigmentation found in natural henna. | |

Sometimes, only one exposure to PPD can cause a series of long term health problems. So keep your health safe by using only natural henna. Here are a few questions you need to ask the artist when thinking of getting a henna design: |
|
| • What kind of henna do you use? | ||
| • Is there PPD in your henna? | ||
| • Do you mix your own paste? | ||
| • What ingredients do you use | ||
| • What colour will the stain be? | ||
|
Remember
that natural henna never produces a black stain and is a very safe product
to use for body art.
