While traditional, pure henna does not contain paraphenylenediamine (PPD), it is often added to henna to create a temporary black tattoo known as "black henna."
Understanding the Difference
It's crucial to distinguish between natural henna and so-called "black henna."
Natural Henna
- Is derived from the Lawsonia inermis plant.
- Produces a reddish-brown stain on the skin.
- Is generally safe when used pure.
"Black Henna"
- Is often traditional henna mixed with PPD.
- Is used to create a dark black temporary tattoo.
- Contains paraphenylenediamine (PPD) which is not a natural component of henna.
- PPD is an allergenic chemical that causes hypersensitivity reactions. The addition of PPD into henna dyes and the potential for this allergenic chemical to cause hypersensitivity reactions is a public health issue.
- PPD is an oxidative chemical used in many home and salon permanent hair coloring products.
- PPD is not a natural ingredient of henna.
Dangers of PPD in "Black Henna"
The main danger lies in the addition of PPD to henna, especially in so-called "black henna," leading to serious health risks. PPD is a known skin irritant and allergen. Reactions can range from mild itching and redness to severe blistering, permanent scarring, and even life-threatening allergic reactions.
Key Takeaway
| Feature | Natural Henna | "Black Henna" |
|---|---|---|
| Color | Reddish-brown | Dark black |
| PPD Content | None | Contains PPD |
| Health Risks | Minimal | Significant; allergic reactions |
| Origin | Lawsonia inermis plant | Mixture of henna and PPD |
Conclusion
Therefore, while pure henna does not contain PPD, the additive PPD is found in "black henna," posing significant health risks due to its allergenic properties.
